Anti Corrosion Mold Bushings , Copper Sleeve Bearing Long Service Life

Copper Based Sleeve Mold Bushings Linear Roller Bearings FZ Ball Bearing Cage

1. Product Description

Copper Based Sleeve Mold Bushings Linear Roller Bearings FZ Ball Bearing Cage are consist of three materials,as copper,or aluminium, pom based.They are machined some regular holes and embedded the steel-ball into. The new craft will prevent the ball getting out of as old,as the ball diameter is larger than the retainer thickness,so it will face to face directly with 90°guide bushing that will bring high precision match now the ball retainer series item are disigned to rotate on the post,as well as maintain it vertical motion.We believe this will give you the benefit of increasing accijracy.

3. Application

Copper Based Sleeve Mold Bushings Linear Roller Bearings FZ Ball Bearing Cage are widely applied in die-set,precision machine tool,engineering machinery , automobile etc.​

4. Advantages

Traditional has the relative motion of the hole and the shaft is a certain gap, and movement between hole and shaft friction coefficient is bigger, use the ball to keep, and the shaft and hole does not directly contact, but by the middle of trace interference ball, and movement precision, rolling friction instead of friction, the flexible rolling friction coefficient is small, long service life, in the case of both rotation, and with no oil sleeve to match the shaft, although can satisfy, but the movement precision is low, with rolling bearings, can only meet the relative rotation of the shaft, and steel ring, the above two conditions are satisfied.
