U-shaped spring for elevator safety gear also be known as "U-shaped spring", "safety gear spring", "elevator safety gear leaf spring", mainly be used for progressive elevator safety gear. Safety gear is the most important safety component in an elevator, the safety of the elevator just can be guaranteed with safe and effective safety gear. And the HEGONG safety gear spring is the core component of safety gear, it is the last barrier of elevator safety. When the elevator falls out of control and exceeds the limited speed, the U-shaped spring CHINA starts to work, which stops the lift car in emergency and clamps it on the guide rail, ensure the safety of the elevator passengers. We have been working closely with a number of well-known elevator manufacturers, and developed U-spring for a number of progressive safety gears successfully. If you have any questions, please contact us (Tech@DiscSpringsMFG.com), our technical engineers will work closely with you to design, develop the proper spring according to your requirements.

Wave springs also are known as "wave spring washers" are round elastic parts with several sine waves on the metal foil ring. There are several structures as the table, including "Single-turn wave springs with partially overlapping", "Single-turn wave springs with gap", "Closed Single-turn wave springs", "Multi- turn (Peak to Peak) wave springs", "Multi-turn (Peak to Peak) wave springs with Shim Ends", "Nested wave springs". Wave spring China is a precise elastic element, which is suitable for mounting in the parts with limited installation space and stiffness requirements that other elastic elements cannot meet. Due to its unique structural form, the total height and working height of the wave spring are lower than traditional elastic elements, so it can reduce the space size of the parts and the overall cost of the product, and has an excellent cost performance.

Serrated Safety Washers is a kind of Belleville Disc Spring with trapezoid cross section and serrations on both sides. Serrated Safety Washers is connected with bolt or screw, it can prevent bolt relaxation after vibration by increasing the friction resistance. Serrated safety washers China are available in two different types: S type is suitable for normal duty, available for screw sizes: M1.6 to M36. VS type is thicker and therefore achieves higher pretensioning loads, be used with high strength bolts, available for screw sizes:M5 to M36. m10 washer dimensions supplier surface Condition And Corrosion Protection: Polish Phosphating and oil Mechanical Zinc Plating Chemical Nickel Plating Docromet / Geomet Coating Electrophoresis If you require an item with different dimensions, material or surface treatment, please contact us (Tech@DiscSpringsMFG.com), our technical engineers will work closely with you to specify or design, and then manufacture the proper serrated safety washer for your application.

Flange Washers also be known as "Flange Bolting Washers", "Spring Washers", be used for the connection between flange and bolt. Its application equipment includes: Reactor, stirrer and heat exchanger flange bolts; Pumps, Fans, Centrifuge Flanges and Anchor Bolts; Power bus and copper alloy bolts;Pipe flange and valve flange bolt. Flange Washers are widely used in industries such as Petrochemical, Power, Metallurgy, Paper, Pharmaceuticals, Food Processing, etc. Bolt flange joints are widely used in pressure vessel and pipe connections, and Leakage is the main failure mode of bolt flange connections. The main causes of leakage includes: differential thermal expansion/contraction, vibration, bolt creep and vibration. By installing flange washers in bolt flange joints, the elastic potential energy stored in the China Flange Bolting Washers can be converted into mechanical energy, to compensate the deformation of gasket and bolt, to ensure the bolt preload meets the sealing requirements, prevent leakage. How do we choose the right flange washers? Firstly, choose size of wholesale flange washers according to the bolt model & required load value. Then select the suitable raw material further according to the application environment. Material such as H13, 17-7PH, Inconel 718 (see the material document for details) are available in case of high temperature, cryogenic (low temperature) and anti-corrosion environment.

PRODUCT DESCRIPTION Standard:F436 Description: F436 washers are commonly used in automobile manufacturing due to their strength and durability. These washers are specifically designed to meet ASTM specifications for mechanical, chemical, and dimensional requirements. They are hardened or carburized for extra strength and are smaller in size compared to standard F844 washers. Zinc plating is a popular choice for F436 washers used in automobile manufacturing. Zinc plating provides corrosion resistance, which is crucial for automotive applications where exposure to moisture, chemicals, and other harsh conditions is common. The zinc plating helps protect the washers from rust and corrosion, ensuring their longevity and performance in automotive assemblies. F436 washers with zinc plating are often used in structural work in conjunction with A325 and A490 bolts. These washers provide the necessary hardness and strength required for automotive applications, ensuring reliable and long-lasting performance.

The local manufacturer who has cooperated for 5 years can't meet the precision requirements of the hydraulic cartridge pressure control valve spool, and the defective rate is up to 70%. They gave up 2 weeks after receiving the order. After AAK took over, 3 targeted processing skills were used. The roundness of the hydraulic cartridge pressure control valve spool accuracy could be less than 0.0005, the finish less than Ra0.02, and the percent of pass was more than 95%. Nabulung was completely relaxed after receiving AAK samples of hydraulic cartridge pressure control valves. Nabulung is from Egypt. In the first half of this year, their engineer asked him to purchase 8 hydraulic cartridge pressure control valve samples for the development of new equipment. The roundness of the hydraulic cartridge pressure control valve spool shall be less than 0.0005 and the finish shall be less than Ra0.02. Nabulung realized that the spool was very difficult. He chose a local hydraulic cartridge valve manufacturer who had cooperated with him for 5 years to make samples. The manufacturer started to try samples. 2 weeks later, the manufacturer gave up. The defective rate of the spool was as high as 70%, and the accuracy was not stable. Nabulung found AAK and sent us an email: I noticed the advantages and characteristic processing technology of AAK in the production of valve spools. Can AAK sample the roundness of valve spool less than 0.0005 and the finish less than Ra0.02? After communication, we learned the high defective rate of the original manufacturer of the hydraulic cartridge pressure control valve. According to the drawings provided by Nabulung, the requirements for this spool are indeed very individual, and the conventional production process does not work, but AAK has some experience in spool production and can adjust the process accordingly. After 36 days, AAK sent 8 samples of hydraulic cartridge pressure control valves. 37 days later, Nabulung emailed us that their engineer was very satisfied with AAK hydraulic cartridge pressure control valve samples, especially the stable accuracy of the valve spool. He was worried for nearly 2 months, and finally he could put it down. The roundness of AAK hydraulic cartridge pressure control valve spool accuracy can be less than 0.0005, and the smoothness is less than Ra0.02, which mainly comes from 3 unique processing methods: 1. Roughly turn the profile of the valve spool, leaving a margin of 0.15mm, slotting, drilling, and straightening with deflection instrument to make the bending less than 0.02N/m. 2. The valve spool shall be subject to heat treatment and rough grinding after the hardness reaches HRC65. The center hole is used for high-precision cone hole positioning, and then the ejector pin holes at both ends of the valve spool are honed to make the roundness of the ejector pin hole less than 0.0005, the finish is less than Ra0.02. 3. Cryogenic treatment, freezing treatment at - 65°C - 75°C for 2 - 2.5 hours, the residual austenite in the valve spool will be transformed into martensite, and the toughness and wear resistance of the valve spool will be improved by at least 2 times. Most manufacturers of hydraulic cartridge pressure control valves ignore this link. AAK hydraulic cartridge pressure control valve, has unique skills to process the valve spool, you can also try a small order! https://www.aakindustry.com/info-det , ail/pressure-control-valves-aak463

AAK hydraulic valve block, from a five axis CNC machining center, is milled with a thread milling cutter, completely replacing the traditional radial drilling machine processed with a formed tap, and the thread surface roughness value is Ra1.6μm. The traditional Ra is at 12.5μm. Ra alone has increased sevenfold. Archie purchased AAK hydraulic valve blocks, which not only stopped losing more than 30,000 dollars, but also made an additional profit of more than 10%. For the hydraulic valve block with conical pipe thread, the pipe thread cannot completely seal oil, which is an industry problem. The vast majority of hydraulic valve block manufacturers use traditional radial drilling machines and formed taps for processing. The surface roughness of their threads is a "mine", especially the processing of offset holes, which is a hot potato. Archie, from Australia, purchased most of his hydraulic valve blocks from India, but these hydraulic valve block manufacturers use radial drilling machines for processing. Archie did not know that this traditional process cannot afford to process tapered pipe threads. The order of more than 30,000 dollars in his hand had been involved for 4 months, but the sample of the hydraulic valve block had not passed the standard. The customer was not satisfied. Archie wanted to give up the order, but he was very depressed because of his high profit and unwilling to lose the customer. Archie occasionally noticed many customer cases of AAK hydraulic valve blocks through B2B. He sent an email to ask if it is possible to produce a special hydraulic valve block for him. After AAK technical team refined the drawings, the whole processing process was implemented and had a foundation. I told him that the bottom diameter of the oil hole and valve hole of this hydraulic valve block is large, and most of them are offset holes. At the same time, the taper pipe thread of the oil hole is large, and the oil pressure under working conditions is large, so if accuracy can not be guaranteed, all efforts will be wasted. Archie may realize that when come to the point, and asked us to make samples. After 25 days, 5 hydraulic valve block samples were sent out. 3 weeks later, Archie informed us that the customer had approved the manufacturing quality of AAK hydraulic valve blocks, and that there was no tooth breakage on the thread, especially the thread surface roughness value is Ra1.6μm, the customer was amazed, and the whole sealing performance of the hydraulic valve block was also recognized after the pressure test. 6 years ago, AAK hydraulic valve block was processed with a five axis CNC machining center, instead of the traditional radial drilling machine. A thread milling cutter is used to program for milling. At the same time, according to the pipe thread size, the spiral interpolation milling can obtain stable thread quality, and the thread surface roughness can reach Ra1.6μm. The hidden trouble that the pipe thread cannot seal oil is completely solved. A few days ago, Archie told me privately that AAK hydraulic valve blocks not only saved the customer for him, but also increased his extra profit by more than 10%. The boss was very happy and his authority was also great. AAK hydraulic valve blocks, good at high precision, you are welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-valve-blocks-aak397

HIGINSON company plans to develop a new plunger hydraulic cylinder, which needs to purchase the supporting hydraulic directional control valves. Helen, who had just joined the company, stumbled when purchasing the hydraulic directional control valves. Helen has no hydraulic valve supplier and can only purchase from the original hydraulic valve manufacturer of the company. Half a month later, the engineer and technician of the company installed the hydraulic directional control valves purchased by Helen for commissioning, and the plunger hydraulic cylinder dropped intermittently with vibration and noise. The technician pointed out that the hydraulic directional control valves needed to be replaced. Helen contacted the original manufacturer of hydraulic directional control valve. Per the manufacturer, the delivered hydraulic directional control valves met the requirements of Helen's parameters, and the accuracy also fully met the standard. As a novice, Helen was helpless, and the technician did not specifically say why to replace the hydraulic direction control valves. She tried to contact the new hydraulic directional control valve manufacturer to solve the problem. Helen left a message on AAK website: why is the plunger hydraulic cylinder equipped with hydraulic directional control valve noisy? At this moment, we can't tell the reason. After communicating with Helen, I learned the process of purchasing this hydraulic directional control valve and the judgment of technician in their company. AAK engineers are not 100% sure that where the problem is according to the hydraulic directional control valve drawings sent by Helen, the shipment sample of the original manufacturer and the video of their technician's machine test. We are thinking if Helen, as a novice, has mistaken the type of hydraulic directional control valve? The hydraulic directional control valves can be divided into internal leakage type and external leakage type. Combined with the working conditions, this plunger hydraulic cylinder just reverses the oil outlet chamber, and the back pressure is high. If the internal leakage hydraulic directional control valve is used, there will be abnormal phenomena such as vibration or noise. We told Helen our thinking. She really did not note to the original manufacturer that the hydraulic directional control valve is internal leakage or external leakage. I told her that AAK has ready-made samples of the external leakage hydraulic directional control valve. It is recommended to test the machine with AAK hydraulic directional control valve to see if there is still vibration or abnormal noise. A week later, Helen sent an email saying that AAK hydraulic directional control valve was installed and there was no abnormality in the test run. Helen said privately that she contacted many manufacturers of hydraulic directional control valves. AAK was the first hydraulic valve manufacturer willing to help solve the problem in time. With the help of AAK, she passed the probation period smoothly. AAK is her first trusted Chinese hydraulic valve manufacturer. AAK hydraulic directional control valves, do something you trust, welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-directional-control-valves- 187

Cannan is from Israel. Recently, they developed a hydraulic unit, which requires high-precision hydraulic screw-in cartridge flow control valves. The service life needs to be no less than 1 million times. Cannan received a hydraulic screw-in cartridge flow control valve recommended by their original supplier. It was a valve equivalent to HydraForce standard part and all parameters met his hydraulic unit operating conditions. Cannan greatly appreciated the recommendation of this hydraulic cartridge valve supplier, because this standard part can be used instead of customizing the hydraulic cartridge flow control valve specially. What Cannan didn't expect was that after the hydraulic unit had been running for about 6 months, they received customer complaints about several hydraulic cartridge flow control valves leaking. At the beginning, Cannan thought that it was just an isolated case. With more and more complaints at a later time, Cannan realized that the original supplier's hydraulic cartridge flow control valves only had a service life of less than 1 million times. The manufacturer of the original hydraulic cartridge low control valve stated that the high operating frequency of the equipment caused damage to the hydraulic cartridge flow control valve. The only solution is to replace with new ones. Cannan was very helpless. Cannan found AAK hydraulic cartridge valve website on Google. He noticed that AAK has multiple cases regarding the service life of hydraulic cartridge flow control valves. He left us a message: Can AAK guarantee the service life of each hydraulic screw-in cartridge flow control valve over 1 million times? At the same time, he listed us the HydraForce model code of the hydraulic screw-in cartridge flow control valve. I told him that the service life of this hydraulic cartridge flow control valve is not only determined by the selection of materials, the precision of processing, but also the durability testing. AAK controls quality from these 3 aspects. Cannan requested me to send him 30 samples from our inventory. I delivered them within 1 week, and also sent him a video of AAK testing the durability of hydraulic cartridge flow control valves. The key to the service life of AAK hydraulic cartridge flow control valve over 1 million times lies in the selection of materials, precision processing, and durability testing. Let's not talk about the first two aspects, but mainly about the durability testing equipment independently developed by AAK, which is the last eagle eye in the service life of AAK hydraulic cartridge flow control valves. For each batch of hydraulic cartridge flow control valves, we randomly select 20% of the quantity and test the durability of the valves. Set the pressure and flow rate within the required range, set the number of tests, and start testing. During the testing process, the equipment can automatically control the hydraulic cartridge flow control valve to open and close. During testing, if there are any abnormalities, the device will automatically give a reminder. AAK hydraulic cartridge flow control valve, is controlled from 3 aspects, to get a guaranteed service life of 1 million times. You can also give it a try!

Cyrano, an experienced buyer of hydraulic cartridge valves from Greece, encountered difficulties with a batch of hydraulic cartridge relief valves. At the beginning of the year, they developed a hydraulic power unit and used a hydraulic cartridge relief valve purchased from a hydraulic cartridge valve manufacturer in Ningbo. During the commissioning of the hydraulic power unit, the operation was not stable. Their engineer found that when the overflow flow rate changes greatly, it is easy to cause a large change in the pressure at the inlet of the hydraulic cartridge relief valve. The original manufacturer reported that this hydraulic direct-acting relief valve is a standard part benchmarking HydraForce, they should have their engineer to control the system's overflow flow fluctuations, which embarrassed Cyrano. Cyrano found AAK on Google and noticed that AAK has had multiple cases of solving difficult and complex problems for customers. He emailed us to ask, "How to improve the stability of HydraForce's standard hydraulic direct-acting relief valve?". This question is too big to answer. After communication, it was learned that he had encountered a problem matching the standard part of the hydraulic cartridge relief valve with his equipment. The direction is clear, but whether to choose to optimize A to match B or optimize B to match A, there are only these 2 options. AAK engineer asked if it is possible to replace the hydraulic direct acting relief valve with a pilot operated relief valve? AAK can design according to the working conditions. He paid the development fee the next day, and 40 days later, AAK sent samples of the hydraulic cartridge relief valve. Last week, Cyrano informed that after AAK hydraulic cartridge relief valve was installed in the system, when the overflow flow changed significantly, the pressure at the inlet of the hydraulic relief valve did not change much. Their engineers were very happy and there would be no need to change the system. AAK hydraulic pilot operated relief valve can replace HydraForce hydraulic direct acting relief valve, which is actually very simple. The pilot valve and the main valve are combined to form a whole. The pilot valve controls and regulates the overflow pressure, and the main valve functions as an overflow valve. The two ends of the main valve plug are subjected to oil pressure. The main valve pressure spring is made of small stiffness material. When the overflow flow rate changes greatly, the compression amount of the pressure spring does not increase, and the pressure at the oil inlet is stable. 1. AAK hydraulic pilot operated relief valve is equipped with a first liquid chamber and a cavity for installing the valve spool. The first liquid chamber and the cavity are connected through a through hole. One end of the valve spool is located in the through hole, and the other end is connected to a pressure regulating device, which is fixed on the valve body. 2. The main valve seat is provided with an oil inlet and a return port, which are connected to the oil return port. The plug plugs the oil inlet and return ports through their ends and sides, respectively. The plug connects to the valve body through a pressure spring, and the plug has a damping hole. 3. The pressure regulating device consists of a pressure regulating screw and a spring. One end of the pressure regulating screw is connected to the spring, and the other end of the pressure regulating screw is connected to the valve body. The end face of the plug plugged into the oil inlet is a conical surface. AAK hydraulic cartridge pilot operated relief valve, high stability, you can also try it! https://www.aakindustry.com/info-detail , /cartridge-relief-valves-aak539

Last week, the video I sent to Frank about how hydraulic cartridge valve manufacturer AAK processes the valve spool of hydraulic cartridge flow control valves using a centerless grinder was not approved by him, which made me very disappointed and also helped me understand the requirements of German customers for automated production. Frank from Germany needs to develop a hydraulic flow control valve, but there is a requirement for the accuracy of the valve spool, which requires centerless grinding equipment for precision machining. Frank learned that hydraulic cartridge valve manufacturer AAK has this equipment, so he asked me to take a video of the work for his reference. The next day, Frank said, "Why does it still need a person to assist in completing it?"? I realized that Frank rejected the hydraulic cartridge valve manufacturer AAK because of this. But I'm not too worried, because the automated production process is a strong point of hydraulic cartridge valve manufacturer AAK. Although there is no chance for the hydraulic flow control valve this time, Frank, a customer who is meticulous, will definitely return to AAK. 3 days later, I said to Frank, ‘thank you for your reminder. The mechanical arm plan for automatic material retrieval and feeding equipped for the centerless grinder is already in place. It is expected that in 3 months, I will provide a video of the fully automatic centerless grinder processing the hydraulic flow control valve spool. At the same time, I will also send you some previously unmanned fully automatic processing processes’. Let's go back to last week's video to Frank that using a centerless grinder to process the spool of a hydraulic flow control valve. This CNC centerless grinder is equipped with an automatic conveyor belt. The operator only needs to place the rough machined valve spool on the conveyor belt, and the valve spool is sequentially fed into the grinding area. After one machining is completed, it is automatically placed in the next one. The grinding wheel adopts diamond grinding wheel, which provides a basis for the stable accuracy of the valve spool due to its hardness and wear resistance. The control system of the centerless grinder is stable, with no faults during long-term processing, and the stability of grinding provides assurance for the accuracy and stability of the valve spool. Thanks to Frank's advice again. In fact, the more requirements customers have for you, the more they hope you will grow until you meet the qualifications of their preferred supplier. I like this type of customers. AAK hydraulic cartridge flow control valve, German customer's suggestion, AAK landing, you can also give it a try!

Patrick and I know each other at the PTC exhibition in Shanghai. He has worked in HAENCHEN hydraulic equipment company in Germany for a long time. The first thing he said when he saw me was that “I was attracted by the slogan "Hydraulic valve manufacturer of the world's top 500 companies" on your AAK booth”. We talked about the hydraulic threaded cartridge valves for more than half an hour, especially introduced the difference of AAK hydraulic threaded cartridge valves on the specific details. He was surprised that the details of AAK had caught up with his local hydraulic valve manufacturers in Germany. Shortly after the exhibition, Patrick emailed us a hydraulic threaded cartridge valve with high parameter requirements. In particular, the durability of the hydraulic threaded cartridge valve should be more than 2 million times. All quality details should be compared with their local suppliers in Germany. The drawings attached to the email indicate the detailed data and working condition requirements. AAK is required to send 12 hydraulic threaded cartridge valve samples within 4 weeks. After analysis and comparison, AAK engineers found that this hydraulic threaded cartridge valve is not only durable for more than 2 million times, but also has high accuracy requirements. In particular, the internal leakage requirement of hydraulic threaded cartridge valve is 2drops / min, which is 60% higher than the international general standard. Although the requirements are high, we are still confident. 4 weeks later, AAK sent 12 hydraulic threaded cartridge valve samples. A month after the hydraulic threaded cartridge valve samples were sent, Patrick emailed that AAK did make him realize that it was different from other hydraulic valve manufacturers. At that time, he emailed to 4 Chinese hydraulic threaded cartridge valve manufacturers and a local manufacturer in Germany. Two of the 4 Chinese hydraulic valve manufacturers gave up directly. Only AAK and another hydraulic thread cartridge valve manufacturer confirmed to make samples. They tested and compared the sample parameters of the three factories. AAK's accuracy and durability are not only much higher than those of its Chinese counterparts, but also benchmarked with their local manufacturer in Germany. Although the quotation of AAK hydraulic threaded cartridge valve is much higher than that of its Chinese counterparts, it still has advantages over the hydraulic threaded cartridge valve purchased locally in Germany. Purchasing from AAK is the best embodiment of cost performance. AAK hydraulic threaded cartridge valve has three absolute advantages and has already surpassed its domestic counterparts.   1.  AAK has a high-precision CNC machining center imported from Switzerland and various independent fixtures upgraded and refitted by itself, which eliminates human errors and ensures the first step of accuracy.   2.  AAK engineer team with more than 10 years of technical experience, independent professional research and development, combined with unique research and development technology, to select the raw materials and components according to the working conditions of customers' actual needs, realizing the personalized customization demand of hydraulic threaded cartridge valves, which can not be achieved by 95% of domestic peers.   3. AAK has been OEM for 3 Fortune 500 companies for 10 years. The quality control process is strict, and it is stricter than the ISO certification system. It never relax their requirements, stick to the details and increase R & D. Ensure that the valve spool and valve sleeve of each hydraulic threaded cartridge valve have low friction, anti-fatigue, long service life and high precision. AAK hydraulic threaded cartridge valve has surpassed its domestic counterparts and benchmarked the local manufacturer in Germany.
