Detailed Product Description:Hybrid construction ceramic bearing

Ceramic ball bearing especially Si3N4 have the following performance as low density, high strength, low friction coefficient, electrical and magnetism resistance, wear resistance, well rigidity, lubrication and maintenance free when working, it's the best choice for rollers (inner ring and outer ring are made by metal) of the hybrid construction which are used in high-speed, high accuracy and long life environments.

Detailed Product Description: Full ceramic bearing of material Si3N4

  • Full 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 could endure heavier load and could be used in higher temperature environment. Also we could offer precision which generally used in high-speed and high-rigidity spindle.the manufactured clearance could be P4 TO UP grade.
