FZH Brass Cage Ball Retainer Bush

FZH Ball Retainer
Structure: Copper Retainer + Steel Ball

This is copper based material, on which the rollers are arranged orderly in certain angle and intervals. Moreover, the retaining technique is improved that dropping of the rollers can be thoroughly prevented. The friction is low and can move freely both in redial and in axial directions, and the bearing is in high precision. This is a young generation of the roller bearing which can roll in high speed, and is used in rolling frame of cold impact molds, high precision machine tools and their accessories.

The steel ball array is mainly divided into two categories: spiral array and straight line array.

►Application:
FZH Ball Retainer Bearing & Bush is a new generation replacement of guide pin bush. With high speed movement, this is mainly used in high precision punching tool, high precision machine tool, etc.
