Product Description

 Polymer Plain Bearings & Sleeve Bearing | PTFE lined wrapped bearings

 

 

PTFE lined wrapped bearings

 

Carbon Steel self-lubricating bearings used high quality low-carbon steel plate as base, sintered porous bronze as its interlayer and the Compound of PTFE and Lead as its surface.

 

Our PTFE lined wrapped bearings have been developed for high duty, oil lubricate applications. Such applications include, but are not limited to:

  • Automotive suspension struts
  • Shock absorbers
  • Hydraulic cylinders
  • Gear pumps and motors
  • Axial and radial piston pumps and motors

Our VIIPLUS range of PTFE lined wrapped bearings is suitable for dry running, low friction, low wear applications. These wrapped bearings have excellent sliding characteristics forming a transfer film that can protect the mating metal surface.

 

We are able to offer PTFE lined wrapped bearings in metric plain, imperial plain, metric flanged, metric washers, imperial washers, metric strip and imperial strip. Special sizes can be produced to customer requirements,

CHARACTERISTICS


Metal-Polymer Low Friction Plain Bearings


Steel + Bronze Powder + PTFE/Fibre(DP4)

 

Self Lubricating Bearings Low-Carbon Steel + Porous Bronze + Red PTFE

 

 

 

 


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.
