We have 2 types of ceramic bearing, hybrid ceramic bearing and full ceramic bearing, the hybrid ceramic bearing has steel inner and outer rings with ceramic balls, as for the full ceramic bearing; the inner, outer rings and the balls are made of ceramic. There are many kinds of ceramic materials, the most common ceramic materials are Si3N4 that stands for the silicon nitride ceramic material and is black colored, SiC stands for the silicon carbide material and also is black colored. and the ZrO2 that stands for the zirconium dioxide, also known as zirconia or zirconium oxide, they are white colored, a ZrO2 ball looks exactly like a pearl. the ceramic material is not stronger than steel, but ceramic bearing are lighter and have lower friction than steel, that makes ceramic bearing go faster with lower heat generated.
Ceramic bearings, stainless steel bearings, hybrid bearingsDemension: 15X24X5mmFull ceramic (All -ceramic) bearing of ZrO2 materialFull 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 materialFull 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) bearings fo full complement ballsFull 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 cageCeramic 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 bearingCeramic 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.Stainless bearingsThe high performance stainless steel bearings can provides not only with the cleanliness and corrosion resistance characteristic also with the high accuracy and excellent wear resistance compare to the high carbon chrome steel bearings. The rings and balls are made of the material as a standard structure of stainless steel bearing. The rings and balls are made of the material AISI440C(9Cr18Mo or 9Cr18), the cage and the framework of seal adoption the AI304 or AI316, production accuracy couldreach ISO standard ABEC-1 and above, and the vibration level reach Z1 grade and above.We also can offer non-standard stainless steel bearings to meet some special type needs in engineering. Compare to high carbon chrome martensite stainless steel bearing. Austenite stainless steel bearings have even more excellent corrosion and wear resistance, magnetism resistance. The whole Austenite stainless steel bearings are made of AISI SUS316L(316) or SUS304(including inside and outside rings, balls and cage). Austenite stainless steel bearings can not harden completely by heat treatment, so it should not choose for heaver load or higher speed.
