Description:
 
THRUST ROLLER BEARINGS DESCRIPTION:
 
Thrust roller bearings can accommodate heavy axial loads. Bearings of some structural groups can additionally accommodate slight radial load. They allow much lower rotational speeds as it is compared with other types of bearings.
 
Cylindrical Roller Thrust Bearing
 
1) single direction bearings with cylindrical rollers and a solid cage.
 
 
2) single direction double-row bearings with cylindrical rollers and a solid cage.
 
Two short rollers of varying lengths are installed into the pocket of the cage instead of one long roller in order to reduce the slippage occurring between the rollers and ring raceways due to the diffrence of linear velocities.

 
Competitive Advantage:
 
1. Quality level: reach the same level as the Japanese and European bearings
2. Tolerance level: ABEC-1 (P0), ABEC-3 (P6)
3. Less coefficient of friction
4. High limiting speed
5. Large size range
6. variations of structure
