POM Coated Self Lubricating Thrust Washer

Product Details

1.Product Introduction:

POM based thrust washers

STRUCTURE:

1. POM thickness 0.30 to 0.50 mm. It provides high wear resistance and low friction. Even if there is only a small amount of lubricant supplied, the bearing surface has a circular indentation pattern and the bearing assembly should be greased.

2. The thickness of sintered bronze powder is 0.20-0.35mm. A special powdered copper composition is heat fused to the steel backing. This contact layer acts as an anchor for the PTFE layer and performs heat accumulation away from the bearing surface.

3. Low carbon steel, the base of the bushing, steel back provides excellent stability, load bearing and heat dissipation characteristics.

COMPOSITION: Steel Back + Porous Bronze Sinter + POM with Lubrication Indents
