Bronze + Bronze Powder + PTFE/Fibre(DU-B)
Dry Maintenance Free Bronze Base DU-B Self Lubricating Bush SF-1B
· Very good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions
· Suitable for lubricated applications
· Suitable for linear, oscillating and rotating movements
· Bronze back offers improved corrosion resistance in humid/saline environments
· Suitable for dry running, low coefficient of friction, lower wear, good sliding characteristics, the transfer film created can protect the mating metal surface, suitable for rotary and oscillating movement. Very high chemical resistance, low absorption of water and swelling, also performs very good lubrication feature, the bronze backing provides the improved corrosion resistance comparing with VSB-10.
1. PTFE/fibre mixture thickness 0.01~0.03mm, 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/Fibre mixture.
3. Bronze backing, provides exceptionally high load carrying capacity, excellent heat dissipation and very good corrosion resistance.
