Silicon Nitride Bearings
Gongtao company specilize in making various ceramic bearing made of ZrO2,Si3N4 ect.Full ceramic bearing have excellence performance as special electrical and magfuteism resistance, wear and corrosion resistance,lubrication and maintenance free when working,especially high and low- temperature application .etc. could be used in awful environment and specially condition. The rings and balls made by full ceramic material:ZrO2, as a standard constructure,the cage made by PTFE, generally we also could make the cage
The purpose of a radial bearing is to reduce rotational friction and support loads. This is achieved by using two races to hold the balls and to spread the load through the balls. As the bearing race rotates it causes the balls to rotate. The ball provides for substantially less rolling resistance and coefficient of friction than if two flat surfaces were rotating.
