Bi-metal Steel Backed Bronze PTFE/Fibre Bearing Bushing


Suitable for use under dry operation, with low coefficient of friction and lower wear ratio. Provides good lubricating characteristics through the transfer a film to protect the mating metal surface. Application that require rotary and oscillating movements. Very high chemical resistance, low absorption of water and swelling. Has very good lubrication features, and is enhanced by the bronze backing that improves corrosion resistance comparing with CSB-50.

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.

Typical Applications

This bearing bushing material meets the demanding criteria for long life and trouble-free performance with or without lubricant, of high safety factor even.
The bronze backing provides a high corrosion resistance, anti magnetic properties and a good thermal conductivity, The bearings are particularly appropriate for high temperature environment where no oil is efficient and the machine must be under successive long period working condition. The typical applications covered steel metallurgy industry such as bushes for roller grooves of successive casting machines, cement grouting pumps and screw conveyers for cement and so on.
