PM POM Lined Slide Bush

PM POM lined steel backing Multi-layer slide bearing 

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.


PM pom lined steel backing boundary lubricating bearing is in steel backing with bronze sintered middle layer, surface sintered POM plastic with oil pockets.It is suggesting using after greased.

Also it can be in material of stianless steel(PMSS) and bronze (PMB).Shapes in cylinder (PM-S) and flanged (PM-F)
