The standard range of composite bearings is very comprehensive and covers almost every standard size. This range comprises bushing and flanged bushings, thrust washers and strips.

Product Details

Materials: bronze or iron powder

sintered oil iron bearing is made by bronze or iron / stainless steel powder, mold pressed under high pressure and then sintered under high temperature, and oil is soaked into the spreaded tiny pores of the metal under vacuum. Sintered bushing is widely used for domestic electric equipments, electirc tools, woven machines, chemical engineering machines, automobiles industry,etc.
