1, no oil lubrication or less oil lubrication, can not be refueling or difficult to refuel the place, can not be used in the maintenance or less maintenance.
2, wear resistance, the friction coefficient is small, long service life.
3, the amount of elastic and plastic, can be distributed in a wide contact with the stress surface, improve bearing capacity.
4, static friction coefficient is similar, can eliminate the crawl at low speed, so as to ensure the accuracy of mechanical work.
5, can make the machine to reduce vibration, reduce noise, prevent pollution, improve working conditions.
6, in the course of the operation can form a transfer film, play a role in the protection of the grinding shaft, no bite axis phenomenon.
7, for the hardness of the grinding shaft requirements are low, not the quenching and tempering of the shaft can be used, thereby reducing the processing of the relevant parts of the difficulty.
8, thin-walled structure, light weight, can reduce the mechanical volume.
9, steel can be plated on the back of a variety of metal, can be used in corrosive media; has been widely used in a variety of mechanical sliding parts, such as: printing presses, textile machines, tobacco machinery, micro-motor, automobiles, motorcycles and agriculture and forestry machinery and many more.
