INW-10W Dry bushing with Tin outside SF-1W DX DU Bushing without Pb Steel + Bronze Powder + PTFE/Fibre
Features:
INW–10W 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 CSB-40 improved the friction and much good wear resistance over the common CSB-50 range under lubricated operation.

Structure:
1. PTFE/Fibre mixture thickness 0.01~0.03mm. It is thecontact surface for the rotating shaft. Minute partides of the PTFE layer and the sintered bronze material combine to create a solid lubricant film, which coats the shaft.
2. Sintered bronze powder thickness 0.20*0.35mm,A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the PTFE layer and conducts the thermal build up away from the bearing surfaces.
3. Low-carbon steel backing. Setting the foundation of the
bushings, the steel back provides exceptional stability, load
carrying and heat dissipation characteristics.
Typical Applications:
1. This material meets the demanding criteria for long life and
maintenance free performance with or without lubrication.

graders and other construction, auto machines, specific uses in
power steering cylinders, steering gear thrust washers, disc
brakes, calipers and pistons, shock absorbers, governor linkage,
windshield wiper motor, tilt gear assemblies...
2. Business machines: photocopy machines, typewriters, mail
sorters, postage meter systems, computer terminalprinters and
peripheral equipment,automaticprinting devices, mail processing
