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:40X52X7mm

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

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.
