Sleeve Plain Bearings and Sleeve Bearings Hydro - Cylinder Plain Sleeve Bearing , Bronze Graphite Bushings For Rotating Movement
Sleeve bearings steel bronze bushings, journal bearings or plain bearings facilitate linear movement between two parts. DP4 CYLINDRICAL RED PTFE | VSB-40
PTFE Bushes Manufacturers, Suppliers & We are a well-established firm that has made its presence in the industry, by supplying PTFEBush . PTFE is a self-lubricating material, provides low friction coefficient. It is ideally suited for the Hydraulic Cylinder
TECHNICAL DATA
STRUCTURE & COMPOSITION
· Metal-Polymer Composite Bushing Material
· Steel back + Porous Bronze Sinter +
· PTFE + Fillers
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 VSB-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.
