690 Series Miniature Ceramic Deep Groove Balls Bearings Of ZrO2/Si3N4/SSiC
Description of Miniature Ceramic Deep Groove Balls Bearings:
Our company can produce many kinds of ceramic bearings. Now we are mostly speciallizing in the automatic production of 608 ceramic bearings and other models of miniature ceramic deep groove ball bearings. The material of races and balls can be chosen among Si3N4 (silicon nitride), SSiC (silicon carbide) or ZrO2 (zirconia) and fitted with cage in material of PEEK, , Nylon or PFA. Welcome your inquiry.
