Our Advantages for PVC bush
2.Minimum wall thickness, minimum space requirements
3.Accommodation of heavy loads
4.Wide range of temperatures
5.Good sliding properties
6.High wear resistance
7.No machining required.
It has a certain gap between the hole and the shaft having a
traditionalrelative motion, and the motion coefficient of friction
between the large hole and shaft, ball retainer after use, so no
direct contact with the shaft and thehole, but through the middle
trace interferencethe contact with theball, so high precision.
Rolling friction instead of sliding friction, the rolling flexible,
low friction, long service life.In both the rotation, another
movement of the occasion, with no oil or refuel thesleeve and the
shaft to match, although they would meet the requirements, but to a
lesser movement precision rolling bearing, can only meet the
relative rotation of the occasion, andthe use of ball holdingafter
the circle, the above two conditions are satisfied, this product
has been widely used in Die frame, high-precision machine tools,
machine tool accessories and high accuracy is required axial or
neckto move simultaneously occasions. Be moredifferent occasions,
respectively copper-elect linear bearings, linear bearings and
plasticbase aluminum linear bearings.
