W-PM Metal Backing POM Composite Thrust Washer

is made of triple layer composites: carbon steel as base, porous bronze intermediate layer, POM & Pb (or non-Pb mixture) inner surface layer. The POM inner layer pressed with many oil pockets to store enough grease. Also it called SF-2 in China and DX , PAP P20 overseas.

The products are widely used in machinery industry, such as auto machines, punch machine, forging and pressing machine, vehicle chassis, lifting equipment, mining machinery, steel industry, etc.
