JF型双金属合金的技术标准 Specifications for JF Bronze Alloys

该产品以优质低碳钢为基体，表面烧结铜粉，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。

JF Bimetallic self-lubricating bearing used high quality low-carbon

steel plate as base, sintered porous bronze as its surface, suitable

for rotatory oscillating, reciprocating movements on the conditions

of high load.low speed, low friction, well wear resistance, long

lifetime and better prevent from holding-on.The bronze layer

surface can be machined with various of grooves, oil pockets in

terms of different work condition.The product is widely used in

mining machinery, automobile, building machinery,agriculture

equipment, rolling steel industry etc.
