6812 6812CE Full Ceramic Bearing Si3N4 Material All Silicon Nitride Ceramic 6812 Ball Bearings 60 * 78 * 10 mm

BearingsBearing1 Properties of full ceramic materialsCeramic Bearings, including components made from ceramic, have the special properties that steel bearings do not have, such as being non-magnetic or insulating. They can be used in new applications where conventional bearings have not been practical.Ceramic Bearings are highly heat resistant, enabling a rolling bearing to be practical in a high temperature environment. The low density of ceramic decreases the centrifugal force induced by rolling elements (balls or rollers), contributing to an increased speed of the apparatus. 2 Structure of full ceramic BearingsFull ceramic (All-ceramic) bearing of Si3N4 materialFull ceramic bearing made with Si3N4 have some better performance than ZrO2, the rings and balls made by full ceramic material:Si3N4, as a standard construction, the cage made by PTFE, Compares than the material of ZrO2 ,The SiN4 ceramics bearings could endure heavier load and could be used in higher temperature environment.Item: 6812CEBore Dia (d): 60 mmOuter Dia (D): 78 mmWidth (B): 10 mmCage Material: PEFTBearing Material: Silicon NitrideDynamic Load Rating (Cr) (N): 8050Static Load Rating (Cor) (N): 7420Max Speed (X1000 RPM): 14Ball Qty: 21Weight (g): 72.8Widely used in household appliances, garden machinery, outdoor vehicles, industrial production, etc. Suitable for skateboards, longboards, inline skates, scooters, robots, ship rudder axles, etc.Features: small friction, fast speed, smooth, low noise.
