The material has good wear resistance and it is suitable for middle to high load applications under the work conditions of impact load and dusty environment. A pre-lubricating is necessary before assembling. The applications of this material include the commercial vehicle axel, brake system,suspension system, air compressors, hydraulic piston pumps, motors, as well as agriculture machinery, forest machinery and material handling machinery.

Application of PVDF in High Temperature Bearings

Because the PVDF high temperature bearing seat should not only meet the requirements of high-precision stamping bearing seat, but also meet the requirements of high temperature stamping bearing seat, the following two points need to be taken into account when considering the fit and clearance of PVDF high temperature bearing seat:

1. Size change and hardness change from room temperature to high temperature;

2. Force system change and shape change caused by centrifugal force at high speed.

PVDF high temperature bearing pedestal mounted for shaft and hole punching parts of the bearing should be higher than the general requirements of dimensional accuracy, form and position accuracy, especially the alignment of the hole or shaft neck and shoulder vertical degree, it is important to note that when considering these problems, must pay attention to the PVDF high speed and high temperature factors in the operation of high temperature bearing seat.

The PVDF high temperature bearing seat is required to have the best clearance under the working condition, that is, at the working temperature, and this clearance is formed under the precise alignment of the center of the inner and outer ring ball groove.At the same time, because the PVDF high temperature bearing seat strives to reduce the relative sliding and internal friction, it is best not to adjust the clearance of the PVDF high temperature bearing seat by the method of relative dislocation of the inner and outer rings along the axial direction.
