The thrust bearing consists of a thrust retainer assembly with a needle or cylindrical roller or ball and a thrust washer.
The needle roller and cylindrical roller are held and guided by the thrust cage.
Because the high precision cylindrical roller (needle roller) increases the contact length, the bearing can obtain high load capacity and high stiffness in a small space.
Another advantage is that if adjacent parts surface suitable for raceway surface can be eliminated gasket, can make the design compact, DF thrust needle roller bearings and thrust cylindrical roller bearings using needle roller and cylindrical roller surface for modification, can reduce the edge stress, improve the service life.
