    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.

    Description


    VIIPLUS bushes are produced in a lightweight, compact material with minimum bulk, simplifying shaft assembly. Featuring high-level chemical resistance, shafts can be covered or plated with materials resistant against chemically aggressive liquids, gas or solids, through the application of an additional galvanic layer. This type of bush does not require lubrication and its operating temperature is between -195°C and +280°C.

    Rolled Dry Sliding Bearings (PTFE)


    Steel + Bronze Powder + PTFE/Fibre(DU)

    Characteristics


    VSB-10 Self-Lubricating Multilayer Composite Bushing

    • 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.

    Strusture


    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.
