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.
