Application Features

●Oil-free lubrication or low-oil lubrication is suitable for places where it is impossible or difficult to refuel. It can be used without maintenance or with little maintenance.
●Good wear resistance, low friction coefficient and long service life.
●With appropriate elasticity and plasticity, it can distribute stress on a wider contact surface and improve the bearing capacity of the bearing.
●The static and dynamic friction coefficients are similar, which can eliminate creeping at low speed, thereby ensuring the working accuracy of the machine.
●It can reduce vibration, reduce noise, prevent pollution and improve working conditions.
●During operation, a transfer film can be formed to protect the grinding shaft without biting the shaft.
●The hardness requirement for the grinding shaft is low, and shafts that have not been quenched and tempered can be used, thereby reducing the processing difficulty of related parts.
●Thin-walled structure and light weight can reduce the size of the machine.
●The back of the steel can be electroplated with a variety of metals and can be used in corrosive media; it has been widely used in the sliding parts of various machines, such as printing machines, textile machines, tobacco machinery, micromotors, automobiles, motorcycles and agricultural and forestry machinery, etc.
