ceramic bearing can be used in the most inclemency environments as corrosive,low temperature, high vacuum. The normal used ceramic materials with ZrO2

Full ceramic bearing made with Si3N4 have some better performance than ZrO2, the rings and balls made by full ceramic material: Si3N4,

Ceramic ball bearings, stainless steel ball bearings, hybrid ball bearings

Demension:8X24X8mm

Full ceramic (All -ceramic) ball bearing of ZrO2 material

Full ceramic bearing have excellence performance as special electrical and magnetism resistance, wear and

corrosion resistance, lubrication and maintenance free when working, especially high and low-temperature

application,etc.Could be used in awful environment and specially condition. The rings and balls made by

full ceramic material: ZrO2, as a standard constructure, the cage made by PTFE, generally we also could

make the cage with GRPA66-25, PEEK, PI, AISI SUS304,SUS316,Cu,etc.

Full ceramic (All -ceramic) bearing of Si3N4 material

Ceramic ball bearings, stainless steel ball bearings, hybrid ball bearings

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 load and could be used in higher temperature environment.

Also we could offer precision ceramic bearing which generally used in high-speed and high-rigidity spindle,

the manufactured clearance could be P4 to up grade.

Full ceramic (All-ceramic) ball bearings fo full complement balls

Full ceramic bearing of full complement balls has an add-ball gap on its side. Because using no cage

design, the bearing able to install more ceramic balls than the standard construction, so the heavier

radial load ability increased more.resistance and high temperature application. This series of bearing is

not for high speed choice, it should be to install on the unforced.

Full ceramic (All-ceramic) bearing of ceramic cage

Ceramic cage has excellence performance as wear and corrosion resistance, high strength, lubrication and

maintenance free when working. Adopting the ceramic cage, ceramic bearing can be used in the most

inclemency environments as corrosive,low temperature, high vacuum. The normal used ceramic materials with

ZrO2.

Hybrid construction ceramic ball bearing

Ceramic ball 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 is the best choice for rollers(inner ring and outer ring are made by

metal) of the hybird construction ceramic ball bearing which are used in high-speed,high accuracy and long

life environments. Normally, GCr15 or AISI44C, 316 ,304 makes inner ring and outer ring; The ceramic ball

can adopt ZrO2, Si3N4 or Sic.
