Swbtec Slewing Bearing & Slewing Ring

In the process of slewing bearing use, it will endure 3 different direction
force, including the axial force Fa, the radial force Fr and the overturning
moment M. The combination of the three loads will change as a result of
different working ways and different structural types in different practical
applications, sometimes it may be bear two loads, sometimes there is just one
load. This requires the slewing bearings to have high stability of quality,
SWBTEC slew bearing, from raceway hardening to gear hard treatment, we strive
to excellence.

Tips For Slew Bearing Selection
For slew rotary table bearing selection, we only talk horizontal installation,
if is vertical installation, please contact with our engineer before design.

There are single row type slew bearing, crossed roller slew bearing, double row
slew bearing and triple row slew bearing, Based on our experience, here is our
advice:
when the raceway center diameter is smaller than 1.8 meter, then the single row
type slewing bearing is the preferred alternative, when the raceway center
diameter is bigger than 1.8 meter, the triple row slew bearing is preferred
one. Single row type ball bearing swing has bigger load capacity than crossed
roller type and double row with different diameter ball type slew bearing when
there is the same size structure. so we strongly advise to prefer our Q type
single row four point contact ball slewing bearing.

How Does A Slew Ring Work
Change the way of moving from sliding to rolling, reducing frictional
resistance, this is how turntable bearing working.
The turntable bearing mainly depend on lubrication and friction to achieve the
moving. In the interior, it relies on the mutual friction between the ball and
the ring for the purpose of moving. Externally, it relies on the friction
between the turntable bearing and other components, like pinion to start to
move, It can be used to load large objects, and its own centripetal force
requirement is high, which is determined by its working principle, so it need
good quality forging steel material that can guarantee the work.

Lubrication is also required as the other indispensable factor, or it will
affect the normal operation of the turntable bearing after a long time if there
is huge friction force. Therefore, after a period of time, it is very important
to greased the bearing which can increase the service life.

SWBTEC's Slewing Bearing Application
SWBTEC slewing ring bearings quality has been proved with standard quality and
much longer service life by overseas customer, our slewing ring bearings have
been installed on many kinds of machines, including welding machine, precision
turntable, mooring equipment, snow breaker or shifter, transport, handling,
BMU-building maintenance units etc.

As one of turntable bearing suppliers, we can offer kinds of turntable bearing
for sale, if you have needs to buy any industrial turntable bearing , please
contact us.
