Gate ,Globe ,Check Valve Sleeve Steel Bushes Ball Valve Washer Butterfly Valve Spilt shaft Bushings supplier China Cheap Wholesale Bushing-There are various self-lubricating bearings available for choice. - POLYMER PLAIN BEARINGS Manufacturer for many years.
Valves bearings are used for trunnion bearings, stem guide bearings and thrust washers.
VIIPLUS VALVE SPLIT SLEEVE BUSHINGS bearings are used extensively by manufacturers due to the material’s ability to maintain low friction under heavy loads. VIIPLUS VALVE SPLIT SLEEVE BUSHINGS bearings have a metal backing and a composite self lubricating liner, which gives the combination of high strength, excellent chemical resistance and a low coefficient of friction.
Slide oilless Boundary-Lubrication bearing Lead free Composite bushings
Self‐lubricated Sliding bearings are exhibiting the ability to transfer a microscopic amount of lubrication film to the mating surface to enhance the machine performance & to reduce friction throughout its operating life, without any added grease or oils and ensuring clean, maintenance free operation in the most challenging environments.

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
