High Speed 608 Ceramic Bearings For Roller Skates Skateboard ZrO2 Si3N4 SSiC
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, and Nylon, the material of seals can be chosen among PEEK, , Rubbers and stainless steel. PEEK and 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.
