Metal-Polymer Low Friction Plain Bearings
Steel + Bronze Powder + PTFE/Fibre
Self Lubricating Bearings Low-Carbon Steel + Porous Bronze + PTFE
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.
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.
