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

Tapered Roller Thrust Bearing

This bearing can form a compact assembling in axial direction. The bearing is stiff and can bear heave axial loads but is insensitive to radial loads.

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.

Thrust Ball Bearings

Thrust ball bearing, also known as tbb bearing, is one of the rotary ball bearings. It owns the same features of other ball bearings, i.e permitting rotation among the parts.Thrust ball bearing is composed by housing ring, shaft ring, cage and balls. ZWA Bearings manufacture tbb bearings for different applications, especially in steel making, mining and cement industry.
