CSB-22 PVDF Composite Metal Polymer Plain Bearings with Tin Plating offer a unique combination of properties that make them suitable for various demanding applications. PVDF, or polyvinylidene fluoride, is a highly resistant polymer that provides excellent chemical stability and corrosion resistance. The composite metal structure adds strength and durability, while the tin plating enhances the bearings' surface properties, improving wear resistance and friction behavior.
These bearings are designed to perform reliably in environments with high loads, temperatures, and chemical exposure. The tin plating not only improves wear resistance but also provides a smooth surface for improved lubrication, reducing friction and heat generation. This results in longer bearing life, reduced maintenance requirements, and improved overall system performance.
Wh used in industrial machinery, automotive components, or other critical applications, CSB-22 PVDF Composite Metal Polymer Plain Bearings with Tin Plating are a reliable choice for those seeking high-performance bearings with excellent wear resistance and corrosion protection.

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.
