Product Description

 

Automotive shock absorber DU  and Sleeve Bearings Metal-Polymer Low Friction Boccole DP4 CYLINDRICAL RED PTFE | VSB-40

Description

 

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

Shock absorbers self - lubricating bearings

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.

 

Self-lubricating bearing bearing solution

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.

STRUSTURE


 

1. PTFE/Polymer fibres mixture thickness 0.01~0.03mm. Lead-free bearing layer provides an excellent initial transfer film, which effectively coats the mating surfaces of the bearing assembly, forming an oxide type solid lubricant film.
2. Sintered bronze powder thickness 0.20-0.35mm, provides max. thermal conductivity away from the bearing surface, also serves as a reservoir for the PTFE mixture.
3. Steel backing, provides high load carrying capacity, excellent heat dissipation.
4. Copper/Tin plating thickness 0.002mm, provides good corrosion resistance.
