OEM Valve PAP bushings, particularly those lined with
(Polytetrafluoroethylene), are designed for maintenance-free
applications. These bushings are known for their durability,
chemical resistance, and low friction properties, making them ideal
for various valve and industrial applications where long-lasting
and reliable performance is crucial.
The lining of these bushings provides exceptional lubrication,
allowing for smooth movement of valve components while minimizing
wear and tear. This helps to eliminate the need for regular
maintenance and replacement, saving time and money.
OEM Valve PAP bushings with linings are suitable for a wide range
of fluids, including chemicals, acids, and other corrosive
materials. They can withstand high temperatures and pressures,
ensuring reliable performance in demanding environments.
In summary, OEM Valve PAP bushings with linings offer
maintenance-free, long-lasting solutions for various valve and
industrial applications. Their durability, chemical resistance, and
low friction properties make them an excellent choice for
applications where reliability and performance are paramount.

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.

Bushing With
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.

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. /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.
