Tin-Bronze CuSn8P Wrapped Bearings
Tin-Bronze CuSn8P Wrapped Bearings is made of Tin-bronze CuSn8P with its surface punched with diamond or ball shape oil sockets which are preserved for oil saving. Tin-Bronze CuSn8P Wrapped Bearings has good anti-fatigue and load, anti-erosion and abrasion capacity. Tin-Bronze CuSn8P Wrapped Bearings are widely applied in conditions of heavier load but low running velocity, such as on agricultural, building and engineering machines, etc.
Tin-Bronze CuSn8P Wrapped Bearings is made of high density copper alloy with special formulations, rolled it is made of high quality low-carbon steel strip, rolled and sintered with lozenge or spherical oil indentations on surface. Tin-Bronze CuSn8P Wrapped Bearings is with high density, good load capacity and wear-resistance. It is used in lifting machinery, construction machinery and mining machinery etc.
