MG-800系列双金属轴套、轴瓦、止推垫片，以优质低碳钢为基体，表面烧结青铜粉，适用于高载低速下的旋转，摇摆运动。具有摩擦系数低、耐磨性能好、使用寿命长、抗咬合性能好等特点，铜合金层可根据要求加工出各种类型的油穴、油槽。产品被广泛应用于矿山机械、汽机车、建筑机械、农用机械、轧钢机械等。
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 diuerent working conditions. The product is widely used in mining machinery, automobile, building machinery, agriculture equipment, rolling steel industry etc.
