Ceramic Miniature Deep Groove Balls Bearings Of 600 Series Models
Why choose us:
Now we are mostly speciallizing in the automatic production of 608 ceramic bearings. The material of races and rollers can be chosen among Si3N4 (silicon nitride), SSiC (silicon carbide) or ZrO2 (zirconia) and fitted with cage in material of PEEK, or PFA and seals in material of PEEK, and Rubber. Besides the above mass production model 608 our company can produce other models of miniature ceramic deep groove ball bearings too.
