Needle roller bearings are a type of roller bearings and are classified as either radial or thrust depending on the direction of the load they support. Needle roller bearings include bearings whose rollers slightly exceed the size range of needle rollers as stipulated by ISO. Needle roller bearings include drawn cup, solid radial bearings, and thrust needle bearings. Needle Roller bearings are available in two types: caged and full complement. Drawn cup outer rings are made of carefully selected alloy steel sheet. They are surface-hardened alter precise pressing, giving them a unique structure. The cage of the needle bearing accurately guides the rollers at the pitch diameter of the rollers. The surface of the cage is hardened to reduce frictional torque and increase rigidity and wear resistance.
