Sliding bearings The material in a wide variety of designs is produced by bearings with steel support or bearings with bronze support, PTFE layer, POM layer, composite material, plain bearing strips in the cutting, molding and shaping processes. Standard designs for plain bearings are cylindrical bushes,
Collar bushings, thrust washers, strips
Dry sliding bearings is a composite bearing material comprising 3 layers: Steel support strip, Sintered bronze layer, PTFE layer.
Suitable for dry running
Low friction, high wear resistance
Extremely good performance, as self-lubricating parts materials
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.
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.Lubrication required
Lifetime lubrication possible
Low sensitivity to edge loading
Good damping characteristics
Insensitive to impacts
Good chemical resistance
