Bearing needle rollers

Precision needle rollers have multiple uses in a variety of applications. Needle rollers are mainly used as bearing rolling elements to transmit torque and reduce friction. They can also serve as precision shafts or as precision locating pins.

 The hardness of the bearing steel is the steel of the rolling bearing, the roller and the sleeve. The bearing is subjected to great pressure and friction during operation, so the bearing steel is required to have high and uniform hardness and wear resistance, and high elasticity.
