Bushing Bearings

The basic structure of the self-lubricating bearing is made by sintering three-layer composite materials, and the outermost layer is SPCC elastic steel plated, which can withstand an applied force of 300kgf per square centimeter.

The middle layer is a lead bronze sintered layer, whose function is to roughen the surface of the SPCC steel and make the PTFE+ additives stronger. Therefore, the heat transfer characteristics of the copper layer are used to transmit heat to the machine wall through the outer layer.

The innermost layer is PTFE (and Teflon) + lead (mixture), whose purpose is to reduce the friction coefficient and reduce the amount of friction.

bush bearing can reduce the number of oil supply or the amount of oil, or the bearings without oil supply, used in the difficult to oil and maintain, reduce the number of maintenance, reduce the volume, and save space. Also,bush bearing can reduce costs, reduce mechanical volume, avoid shaft biting, and reduce mechanical noise.
