a. oil lubricated bearings or less oil-lubricated bearings, apply to the oil or difficult to refuel the place, you can not use maintenance or less maintenance.
b. better abrasio n resistance, low coefficient of friction, long life.bearing factory in china
c. has the right amount of elastic-plastic, can stress distribution in a wide contact surface to improve the carrying capacity of the bearing.
d. static and dynamic coefficient of friction similar to eliminate low-speed crawling, so as to ensure the accuracy of the mechanical work.
e. enable machinery to reduce vibration and reduce noise, prevent pollution, and improve working conditions.
f. during operation to form a lubricating film, play a role to protect the shaft, no bite shaft phenomenon.
g. lower for the hardness requirements of the grinding shaft, without conditioning of the shaft can be used, thereby reducing the difficulty of the relevant parts of the processing.
h thin-walled structures, light weight, can reduce the mechanical volume.
i. the bush material as brass, can be used in corrosive media.bearings high speed
