ZrO2 Or Si3N4 Or SSiC 608 Ceramic Ball Bearings With High Precision
Why choose us:
Zhongxing Shiqiang Technology (Tianjin) Co., Ltd. mainly produces ceramic rolling bearings and ceramic balls. At present, the company has a production line for automatic grinding and assembly of ceramic bearings, and designs an annual output of 3 million sets of 608-2PS, 608-2TS, 608-2RS and 608-2Z all-ceramic bearings and mixed ceramic bearings whose precision grades can reach P5 and P4. Our design annual output is 150000000 sets.
Description of All Ceramic Ball Bearing 608 :
1. Races and balls: The material of races and balls can be chosen among HIP-ZrO2 (Hot isostatic pressure sintered zirconia), HIP-Si3N4 (Hot isostatic pressure sintered silicon nitride) or SSiC (Pressureless sintered silicon carbide)
4. Cage and seals: The material of cage can be chosen among PEEK,Teflon and Nylon, the material of seals can be chosen among PEEK, Teflon, Rubbers and stainless steel. PEEK and Teflon material has similar corrosion resistance to ceramic materials, and has a good resistance to radiation, self-lubricating properties, a high degree of wear resistance and other characteristics, which are our recommended materials.
