Metal-Polymer Bushings are made of Steel bronze powder with red PTFE/fiber layers dry bushings
Bushings Composite Self-Lubricating Bushings
Steel Bronze with PTFE Fibre Bushes us in automotive suspension struts, shock absorbers guide
bushing, hydraulic cylinders, gear pumps and motors and axial and
radial piston pumps and motors
Automotive Shock Absorber Du Seres Sleeve Bearings Cylindrical Red
Ptfe Dp4
Composed of steel back, sintered porous copper powder interlayer and ptfe sliding layer (red).The product has low friction coefficient, good wear resistance and self-lubrication performance;Corrosion resistance can be improved by coating the steel back with tin, zinc or copper.Widely used in printing machinery, textile machinery, tobacco machinery, fitness and shock absorber,Dependable quality Sintered parts for automotive shock absorber link bushing
These key self-lubricating bearings help:
Smooth and comfortable riding
Steering and passenger safety, especially at high speeds.
Shock absorbers and struts play an important role in driving
quality and performance of vehicles.
Because shocks and struts have so much to do with the handling of a
car, they can be considered critical safety features.
The structure of the self-lubricating bearing consists of a strong
steel backing with a porous bronze sintered intermediate layer and
a wear-resistant PTFE bearing layer.
Sliding bearings are mounted on high performance shock absorbers and struts to provide higher load, faster speed and longer service life under harsh operating
conditions.
The unique coverage formula of metal polymer composite bushing
makes them ideal prop bearings because they have the following
performance advantages:
Use high-quality wear-resistant bearing coating for longer service
life
Because PTFE (polytetrafluoroethylene) is added to bearing cladding, friction
and energy loss between bearing and shaft are reduced, and damping
response is better.
Improved reliability, excellent resistance to flow erosion and oil
erosion during rapid and repeated shrinkage and expansion of the
buffer or pillar
Reduced weight and more compact design, because can shorten the
length of the bearing, without adversely affecting the service life
of the shock absorber or pillar.
Lead-free metal polymer self-lubricated bearings also provide
performance in heavy oil, oil lubricated applications such as
hydraulic gear pumps and motors, vane centrifugal pumps and
compressors.

VSB-40 low friction bushings offer good wear and low friction performance
over a wide range of loads, speeds and temperatures in dry running
conditions
· Very good performance in lubricated applications
· Good performance in greased applications
· Suitable for linear, oscillating and rotating movements
Suitable for dry running, low coefficient of friction, lower wear,
good sliding characteristics, the transfer film created can protect
the mating metal surfaces, suitable for rotating and oscillating
movement, high chemical resistance, low absorption of water and
swelling. The VSV-40 improved the friction and much good wear
resistance over the common CSB-10 range under lubricated operation.
