SXM 6214 Wire Pulley Ceramic Deep Groove Bearing , High Speed Bearings
Ceramic Bearings are made entirely of ceramic material and are superior to common steel bearings in many ways. Ceramic is the perfect material for any application seeking to achieve higher RPM’s, reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present. Ceramic materials commonly used for bearings are Silicon Nitride (Si3N4), Zirconia Oxide (ZrO2), or Silicon Carbide (SiC.) Features: special electrical and magnetism resistance, wear and corrosion resistance, lubrication and maintenance free when working, high and low- temperature resistance etc. So they are suitable to be used in awful environment and special condition. Applications: cryopumps, medical devices, semiconductors, machine tools, turbine flow meters, food processing equipment, robotics and optics.
