WXZX Full Ceramic Bearing Zirconia Bearing, Deep Groove Ball Bearing, 6006 30x55x13mm, 6005 25x47x12mm, Full Ceramic Bearings 1 Piece (Color : 6006 30x55x13mm)

♥ Since the elastic modulus of ceramics is higher than that of steel, it is not easy to deform when subjected to stress. So it is advantageous to increase the working speed and achieve higher accuracy. ♥ Because of the unique ceramic materials,vacuum oil-free self-lubricating property,in ultra-high vacuum environment, zirconia ceramic bearings can overcome the plain bearing can not realize the problems of lubrication. ♥ The advantages of zirconia ceramic bearings: smooth rotation, corrosion resistance, no rust, oil-free self-lubricating, non-magnetic, insulation, high temperature. ♥ Electrically insulated bearings: Due to the high electrical resistivity, the bearings can be protected from arcing. ♥Package Included: 1 piece Ceramic Bearing
