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.
