Full Complement Balls Of ZrO2 Ceramic Bearings, Full Ceramic Bearings

Full Ceramic Bearings of full complement balls of ZrO2 material has an add-ball gap on its side. Because using no cage design, Full Complement Balls Of ZrO2 Ceramic Bearings is able to install more ceramic balls than the standard construction, so the heavier radial load ability could be increased more. In addition, to avoid the limited of the cage material, Full Complement Balls Of ZrO2 Ceramic Bearings has more corrosion resistance and higher temperature application than the full ceramic bearing of ceramic cage. This series of Full Complement Balls Of ZrO2 Ceramic Bearings is not for high-speed circumgyration, so the side with gap shouldn’t be installed on enduring axial load side. As there are add-balls gaps in the inner and outer rings, Full Complement Balls Of ZrO2 Ceramic Bearings couldn’t be used in more axial load application. The highest temperature of recommendation is 500℃.
