High-temperature applications demand bearings that can withstand extreme heat without sacrificing performance, durability or reliability, we carry inch and metric size high-temperature bearings that maintain exceptional performance at temperatures to 2372 F (degrees fahrenheit) = 1300 C (degrees Celsius). ♦Zirconia bearings (ZrO2) full ceramic bearingConstant working in high temperature till 450 Centigrade ! Application: chemical [...]

Full ceramic bearing made with Si3N4 have some better performance than ZrO2, the rings and balls made by full ceramic material:Si3N4, as a standard constructure,the cage made by PTFE, generally we also could make the cage with GFRPA66-25,PEEK,PI, Phonemic Textiles Tube ,etc. Compares than the material of ZrO2 ,The SiN4 ceramics bearings could endure heavier [...]
