Sintered PTFE and Bronze Powder on Bronze Backing (Maintenance-free Material)
PTFE / Fibre Layer + Bronze Layer + Bronze Backing
Composite material CM1
This is a composite material consisting of three layers: a bronze backing strip and a sintered interlock matrix, impregnated and overlaid with a PTFE / lead mixture. The material shall conform to the characteristics listed in table below. In addition, the condition of the material and its surface finish shall be checked visually. |
|
Structures
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 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.
