MG-800 Bimetal Wrapped Bushings Specication & Tolerance MG-800 Bimetal Wrapped Bushings Specication & Tolerance

◆ Introduction:

MG-800 Bimetallic self-lubricating bearing uses high quality low-carbon steel plate as backing, sintered porous bronze as its liner, suitable for rotatory oscillating, reciprocating movements in the conditions of high load, low speed, low friction, wear resistance, a long working life span on preventing the mating parts from holding-on. The bronze layer surface can be machined with various of grooves, oil pockets in terms of different working conditions. The product is widely used in mining machinery, automobile, building machinery, agriculture equipment, rolling steel industry etc.
