The double metal axle sleeve is a cold steel base, and the surface sintered copper lead alloy, aluminum tin alloy bimetallic shaft sleeve.The work surface of axle sleeve is designed with oil sump to accommodate lubrication under oil conditions. Because it is a kind of roll forming thin-walled shaft sleeve, it can reduce the radial size of the bearing, reduce the volume of the machine and reduce the cost.Dual metal bushings are mainly used in the automotive industry, such as: engine main bearing, connecting rod bushing, rocker arm bushing, transmission gear bushing, spring plate lining of the chassis system, brake shoe bushing and so on.
