693 Si3N4 Full Ceramic Bearing 3x8x3 mm 3mm/8mm/3mm Si3N4 Ceramic Ball Bearing

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.3 DementionsItem: 693CEBore Dia (d): 3 mmOuter Dia (D): 8 mmWidth (B): 3 mmCage Material: PEFTBearing Material: Silicon NitrideDynamic Load Rating (Cr) (N): 332Static Load Rating (Cor) (N): 101Max Speed (X1000 RPM): 101Ball Qty: 6Weight (g): 0.42Widely 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.
