Composite Bearing INW-10 S SF-11S Stainless Steel Backing Bronze PTFE Metric Size


Features:

INW–10S 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.

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. Stainless steel SUS304, 314, 440... gives strong acid and alkali situation.

Typical Applications
SBU-S bearings are of oil resistant, acid resistant and seawater resistant. More over, there is no lead in the PTFE surface layer and is particularly suitable for application in the food machinery, alkali flow meters, pumps motion elements in pharmaceutical machines, printing machines, chemical engineering machines and other ocean industry.

Other Standard SBU-S Shapes

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.
