Rollers

Rollers are the components bored with loads in bearing operation. They are also the weakest component whose quality will directly affect the bearing’s performance like rotating speed, vibration level and flexibility. It’s also the key element for service life of bearings. Based on different categories, rollers can be divided into spherical, tapered, cylindrical rollers. According to different precision level, they are divided into grade I, II and III. 


ZWA’s precision spherical roller bearings are with least grade II and raw materials are with European standard. The production capacity of ZWA is 80,000 to 100,000 piece monthly.

ZWA Bearing Recommendations
  • Thrust Spherical Roller Bearings

    Thrust Spherical Roller Bearings

    Spherical thrust roller bearings is a kind of thrust rolling bearing. They allow low friction rotation and angular deviation and are designed to bear radial load and one-way axial load.
  • Split 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.
  • Double Row Cylindrical Roller Bearing

    Double Row Cylindrical Roller Bearing

    The rollers of double row cylindrical roller bearing are crossing arranged. While rotating, the wave ratio is one time higher than single-row cylindrical roller bearings.
