Product Specification

Self-lubricating Bearings made to order from china,Compared with normal Plain bearings

 
VIIPLUS CHINA self-lubricating bearings are superior in wear resistance, seizure resistance and friction properties, and realize performance enhancement and maintenance-free.
 

Introduction to Material

 
It consists of polytetrafluoroethylene. is a perfluoropolymer prepared by free radical polymerization of tetrafluoroethylene. Its English name is .
PTPE has high impact strength, low friction coefficient and high oxygen index.
Because of its low friction, it is widely used in sliding parts: bearings and bushes.

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 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. is designed for complete dry friction and a variety of materials are developed for lubrication, friction coefficient and durability.VIIPLUS's metal composite delivers the best performance over the widest range of loads, speeds and temperatures with or without external lubrication.

The product application

Agricultural machinery: tractors, combine harvesters, crop sprayers, bulldozers, grader, etc.
Automobile industry: power steering pump, steering gear thrust gasket, disc brake, shock absorber, door hinge, wiper, chair horn, air valve and solenoid valve;
Office and business machines: copier, fax machine, printer, mail processor, etc.
Hydraulic components and valves: gear pump, plunger pump, vane pump, ball valve, butterfly valve, cylinder, cylinder and other hydraulic components;
Home appliances: refrigerators, air conditioners, vacuum cleaners, sewing machines, cleaning machines, microwave ovens and fitness equipment, etc.
And other logistics machinery, packaging machinery, textile machinery, port machinery, mining machinery and forest machinery and so on.
In actual use, according to the different environment, working conditions and environmental protection requirements, low-carbon steel plate can be changed into copper plate or stainless steel plate, the inner surface of the plastic layer can choose lead or lead-free materials and other polymer filler, the appearance can be tin or copper plating.

Description

 
Rolled dry sliding bearings ()

• 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. /Fibre mixture thickness 0.01~0.03mm. It is the contact surface for the rotating shaft. Minute partides of the 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 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.
