Product Description

Plain bearing Strips hydraulic special Sliding bush PAS Strips Material information in detail DP4 Strip Metric | VSB-40

 

 

Cosidering the wortking principal of oil pump and damper. Hydraulic bearing, Its peformance is same as DP4 and can be is substitute of DP4 abroad.it shows its priority when work under high frequence reciprocating motion with a big side force.covers a wide application in automobile,motor damper and oil cylinder etc.

 

SF-1D hydraulic special material is a material designed in combination with the working principle of oil cylinder and shock absorber. It is more wear-resistant under oil-free conditions. In addition to the advantages of SF-1P, this product is especially suitable for large reciprocating Tendency to the occasion.

 

VSB-40 Metal-Polymer Low Friction Plain Bearings

 

  • Metal-polymer-composite material
  • Seel + porous bronze sinter + RED PTFE modified
  • self lubricating low-maintenance

 

 

Metal-polymer-composite material Steel + porous bronze sinter + PTFE modified

 

Lubricated bearing material with good wear and friction performance over a wide range of load, speed and temperature conditions Particularly suitable for intermittent operation (reciprocating or oscillating movements)

 

 

 

APPLICATION

 

Automotive:


shock absorbers, door,
bonnet and tailgate hinges, steering columns,
clutches, gearbox selector fork guides, wiper
arms, power steering pumps, pedal bushes,
ABS equipment, etc.

 

Industrial:

 

Lifting equipment, hydraulic pumps and motors, pneumatic equipment, medical equipment, textile machinery, agricultural equipment, scientific equipment, drying ovens, office equipment, etc.

Availability

 


Ex stock: To order:
Cylindrical bushes, flanged bushes, t Non-standard parts hrust
washers, flanged washers and strip

 

Hydraulic special bearing especially suitable for reciprocating frequent occasions large lateral force.

Its performance is similar to that of DP4

Which can be used in automotive, motorcycle shock absorbers and various hydraulic cylinders.

 

 

 


improved the friction and much good wear resistance over the common VSB-10 range under lubricated operation, for dry running, low coefficient of friction, lower wear, good sliding characteristics


VSB-40 DP4 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.

5. Steel + Bronze Powder + PTFE/Fibre(DP4)
