Self Lubricating Plain Bushing

The composite ptfe or pom bushings bearings in metal housings is excellent due to the high material self-lubricating and metal steel backed. The bronze backed bearings are adequate for composite bearings in most cases. In general, composite ptfe or pom bushings bearings can be directly mounted in housings designed for bronze bearings. The bearing will close in by an amount equal to the measure of interference with the housing. This close-in must be considered when calculating the installed bore and corresponding shaft diameter.

Modified PEEK with self lubricating additives for applications where chemicals where chemicals may be utilized.Excellent wear in both wet or dry applications. Available with a bronze substrate for use as chemical pump or valve bushings. Extra thick liner allows for slight modifications for shaft misalignment.

The Bushing Valve is a check valve with a standard bushing housing. The bushing is adaptable to many types of service valve applications.Buy Online Today!

VIIPLUS MADE TO ORDER FORM CHINA Steel Metal with PTFE Liner is a proprietary self lubricating bearing material of woven polytetrafluoroethylene (PTFE) fibers applied to a rigid backing. Also available is our innovative fabric-free backing with special low friction coating. Self-lubricating bearings are available with different metal backings in a wide variety of standard configurations, as well as an almost unlimited range of special sizes and configurations. Stainless steel (PTFE) bearings and glide strips offer high compressive strength, high temperature resistance, and have excellent chemical resistance.

VALVE BUSHING  bearings are completely selflubricating, maintenance free and normally run dry. However, they can also be used where lubricating or other fluids are present.

Application

Self-lubricating bearings are typically used in high load applications, including valves, hydro power equipment, lifting equipment, hydraulic pumps and have a long proven history of providing outstanding performance in extreme applications from Ariane rockets to deep sea valves.

VIIPLUS Self-Lubricating Bearings Material provides high-end casting to our valve divisions including materials like (low temperature) carbon steel/ stainless steel/ PTFE Bushing POM Bushes and high bronze alloy steels bearings.All analyses regarding the mold and pattern designs are being performed in our own premises in order to guarantee a constant casting level and quality.

The structural characteristics

VIIPLUS metal composite self-lubricating materials for high quality low carbon steel substrate, sintering porous spherical copper powder layer, the surface of copper is given priority to with PTFE wear-resistant lubricating materials as bearing layer, the material has excellent mechanical bearing capacity, the middle copper powder layer can not only transfer the heat generated by the bearing during operation in time, but also increased the strength of the combination of the plastic layer and substrate.PTFE is designed for complete dry friction and a variety of materials are developed for lubrication, friction coefficient and durability.VIIPLUS's PTFE metal composite delivers the best performance over the widest range of loads, speeds and temperatures with or without external lubrication.

Description

Rolled Dry Sliding Bearings (PTFE)

•  Bushing material suitable for lubricated applications

•  self-lubricating bushings offer very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions

•  Anti-friction bearing suitable for linear, oscillating and rotating movements

• As they do not absorb oil and water, bushes have a low expansion and high conductivity rate, as well as good thermal stability. Furthermore, by using this type of bush, vibrations, noise and pollution are significantly reduced.

Material is designed to operate without supplemental lubrication and will perform excellent when lubrication is present. Low friction, low wear rate, good sliding characteristics and very low absorption are a few of the features of this material. VSB-10 bushings will support rotary, linear and oscillating motion.
 

1. PTFE/Fibre mixture thickness 0.01~0.03mm. It is the contact surface for the rotating shaft. Minute partides of the PTFE layer and the sintered bronze material combine to create a solid lubricant film, which coats the shaft.
 
2. Sintered bronze powder thickness 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. Low-carbon steel backing. Setting the foundation of the bushings, the steel back provides exceptional stability, load carrying and heat dissipation characteristics.
