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

    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.
  • Toroidal Roller Bearing

    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.
  • Single Row Tapered Roller Bearing

    Single Row Tapered Roller Bearing

    It can bear simultaneously radial load and single row axial load. According to contact angle, it is classified into 3 types: small, medial and big cone angle.
