Gate, globe, and check valves are critical components in various industrial fluid systems, controlling the flow of liquids and gases. The performance and durability of these valves depend heavily on the quality of their internal components, particularly the steel shaft bushes and plain bearings.

Steel shaft bushes play a vital role in guiding and supporting the movement of the valve stem. They must withstand high loads and frequent operation while maintaining a tight seal to prevent leakage. Metal polymer composites are increasingly being used in the manufacture of these bushes due to their exceptional mechanical properties.

These composites offer a unique combination of strength, stiffness, and wear resistance. They can also be tailored to specific application requirements, providing optimized performance in a range of environments. In ball valve plain bearings, metal polymer composites offer superior durability and reduced friction, enhancing the overall performance of the valve.

Our company specializes in the production of gate, globe, and check valve sleeve steel shaft bushes and ball valve plain bearings using metal polymer composites. We employ advanced manufacturing techniques and rigorous quality control procedures to ensure the highest levels of performance and reliability.

Whether you're upgrading an existing system or designing a new one, we can provide the right solution for your valve bush and bearing needs. Contact us today to learn more about our products and how we can help you achieve superior performance in your fluid system applications.

8 . Suitable for rotating , oscillating , reciprocating and sliding movement .

1.PEEK/PTFE 0.30~0.50mm. It has high wear resistance and low friction even only minute of lubricant are supplied. The bearing surface carries a pattern of circular indents which will be filled with grease on assembly of the bearing.

2.Bronze layer 0.20~0.35mm. A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the PTFE layer and conducts the thermal build up away from the bearing surfaces.

3.Steel backing.Setting the foundation of the bushings, the steel back provides exceptional stability, load carrying and heat dissipation  Characteristics.
