1, no oil lubrication or less oil lubrication, can not be used for refueling or difficult to refuel the place, can be used in the maintenance or less maintenance.
2, there is the right amount of elastic-plastic, can stress distribution in a wide contact surface, improve the bearing bearing capacity.
3, wear resistance, friction coefficient, long service life.
4, in the course of operation can form a transfer film, play a role in protecting the grinding shaft, no bite-axis phenomenon.
5, static and dynamic friction coefficient is similar to the crawl at low speed to eliminate, so as to ensure the accuracy of mechanical work.
6, can reduce mechanical vibration, reduce noise, prevent pollution, improve working conditions.
7, thin-walled structure, light weight, can reduce the mechanical volume.
8, for the grinding shaft hardness requirements are low, no quenched and tempered shaft can be used, thereby reducing the processing of the relevant parts difficult.
9, the back of a variety of metal plating can be used in corrosive media.
