This is copper or aluminum or plastice
bastics based material, on which the rollers are
aranged oderly 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
frane of cold impact moulds, high precision machine
tools and their accessories.
