The thrust washer valve bushing composite material is a unique material combination that offers exceptional performance in various industrial applications. It consists of a (Polytetrafluoroethylene) thrust washer, valve bushing, and a steel backing. The component provides excellent chemical resistance, low friction, and high temperature tolerance, making it suitable for demanding environments.
The steel backing adds strength and durability to the composite, ensuring it can withstand high pressure and loads. The WC08 and WC60 grades refer to the specific tungsten carbide (WC) content in the composite, which further enhances its hardness and wear resistance.
This composite material is often used in valves, pumps, and other fluid handling equipment where high performance and long-term reliability are crucial. Its ability to withstand corrosion, abrasion, and extreme operating conditions makes it a popular choice in various industries, including petrochemical, chemical processing, and power generation.

CHARACTERISTICS
Metal-Polymer Low Friction Plain Bearings
Steel + Bronze Powder + /Fibre(Metal-Polymer Low Friction Plain Bearings)
Self Lubricating Bearings Low-Carbon Steel + Porous Bronze + Red
VSB-40 low friction bushings offer good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions
· Very good performance in lubricated applications
· Good performance in greased applications
· Suitable for linear, oscillating and rotating movements
Suitable for dry running, low coefficient of friction, lower wear, good sliding characteristics, the transfer film created can protect the mating metal surfaces, suitable for rotating and oscillating movement, high chemical resistance, low absorption of water and swelling. The VSV-40 improved the friction and much good wear resistance over the common CSB-10 range under lubricated operation.
1. /Polymer fibres mixture thickness 0.01~0.03mm. Lead-free bearing layer provides an excellent initial transfer film, which effectively coats the mating surfaces of the bearing assembly, forming an oxide type solid lubricant film.
2. Sintered bronze powder thickness 0.20-0.35mm, provides max. thermal conductivity away from the bearing surface, also serves as a reservoir for the mixture.
3. Steel backing, provides high load carrying capacity, excellent heat dissipation.
4. Copper/Tin plating thickness 0.002mm, provides good corrosion resistance.
