High Quality Roller Bearings
Roller bearing rotates the bearing parts by rolling contact of its major
components. Different cheap roller bearings are able to bear different axial
and radial loads.

Compared with ball bearings, the major components of roller bearings are linear
contact each other which enables the bearing with less deformation after high
load.

Choosing proper shaft roller bearings should be based on the detailed working
condition. ZWA, a local China roller bearing factory that has its own roller
bearing factory, provides the service and technical advice on the bearing
selection. Please contact us for optimized your equipment performance by the
most suitable bearings.

Spherical Roller Bearings
Spherical roller bearings are designed to adapt to severe misalignment caused
by mounting or deflection on the shaft & housing. Not every type of bearing has
the ability to face the challenge of misalignment. Meanwhile, due to its two
row of rollers, spherical roller bearings are able to bear high radial loads
and some axial loads. They adopt a spherical or crowned rollers as rolling
elements and raceway of the outer ring is also in spherical shape. For shock
loads, their feature of self-aligning helps to absorb but has limited
capabilities to high speed. As one of the widely used bearings, spherical
roller bearings do you a favor in obtaining lower maintenance cost, increasing
the productivity and prolong the service life.

Cylindrical Roller Bearings
Cylindrical roller bearings ( also called CRB in short) are a kind of radial
rolling bearings with cylindrical rollers. The rollers are lined in parallel
shapes, in between the rollers are cages that are able to avoid the leaning of
roller or friction between rollers. In consequence, the rotating torque is also
avoided. The contact between the cylindrical rollers and the raceways is linear
contact. In general, cylindrical roller bearings adopt pressed steel cages or
machined brass cages.

Tapered Roller Bearings
Tapered roller bearings, also known as TRB bearing, are also a kind of bearing
that can be separated, a tapered raceway featured the inner and outer rings.
Tapered roller bearings can bear large axial forces and function like thrust
bearings. They can also manage large radial loads. Tapered bearings are an
improvement on journal bearings. Tapered roller bearings don't need to add
frequent lubrication to avoid overheating and failure.

Toroidal Roller Bearing
Toroidal roller bearings are kind of new single-row radial bearing. It has
crowned symmetrical rollers and circular ring raceways.The rollers of the
toroidal bearings are self-guiding, that's to say they adjust the position in
which the loads are averagely distributed over the length of the rollers no
matter the inner ring is axial displaced or not. The raceways of the inner
rings and outer rings are concave and arranged symmetrically about the center
of the bearings.

Split Bearings
Split roller bearings are specially designed based on the original spherical
roller bearings and cylindrical bearings. The aim of split bearings is to solve
the problem of quick replacement of bearings at unattainable positions or
points. They are suitable for the application of lower rotating speed, higher
load, shock loads, harsh working conditions and those positions where it is
hard to access. ZWA's split bearings include split spherical and split
cylindrical roller bearings.

Major Process Equipment Maintenance and Repair
Bearing maintenance process and initial diagnosis on performance

Bearing maintenance can be divided into five steps:

Firstly, dismount the bearing and take record for the visual appearance.

Secondly, confirm the remaining lubricant amount.

Thirdly, rough wash the bearing's lubricant or cohesion with brush. In this
step, the bearings must be soaked in oil.

Fourthly, fine wash the bearing by rotating the bearing in the oil.

Lastly, re-lubricate the bearing with oil or grease.

Initial diagnosis on bearing performance after maintenance

Check the dimension, tolerance, precision of rotation, interior clearance,
appearance of raceways, cages and seals etc.
