Description fo ceramic bearings:
Full ceramic bearing have excellence performance as special electrical.
Magnetism resistance, wear and corrosion resistance, lubrication and maintenance free when working.
Especially high and low-temperature application. etc..
It could be used in awful environment and specially condition.
Hybrid Ceramic Bearing:
Ceramic bearings offer a significant performance improvement from those made from traditional steel. Our ceramic bearings are manufactured from silicon nitride (Si3N4), an exceptionally hard non-metallic material rated for speeds to 2 million dN, offering a wide selection of benefits.
Hybrid Bearings have steel rings and ceramic balls. Si3N4 Ball is the most popular for the balls as it has only 40 percent of the density of bearing steel but is much harder giving greater wear resistance. Zirconia is heavier with 75 percent of the density of steel so is less suitable for hybrid bearings...
Full Ceramic Bearing:
Full Ceramic Bearings are made entirely of ceramic material and are superior to common steel bearings in many ways. Ceramic is the perfect material for any application seeking to achieve higher RPM's, reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present. Applications such as cryopumps, medical devices, semiconductors, machine tools, turbine flow meters, food processing equipment, robotics and optics. Ceramic materials commonly used for bearings are Silicon Nitride (Si3N4), Zirconia Oxide (ZrO2), or Silicon Carbide (SiC. )
Race material | Si3N4, ZrO2, SiC, POM, PP etc |
| Ball material | Si3N4, ZrO2, SiC |
| Cage | No cage/ Si3N4, ZrO2, SiC/PEEK,PTFE etc |
| Bearing type | Deep groove ball bearing, insert bearing, self-aligning bearing etc |
Features of ceramic ball bearing:
1.anti-corrosion
2.high temperature
3.light weight ,low noise
4.high speed than steel ball
Ceramic ball bearing have so many advantage:
1.Because ceramic almost afraid of corrosion, so the ceramic rolling bearing is suitable for the corrosive fluids in harsh conditions
2.Due to the density of ceramic rolling ball is lower than steel, more much lighter weight, so the external ring spinning the centrifugal effect can reduce 40%, thus greatly extend the service life.
3.Ceramic is affected by heat bilges cold shrink is smaller than steel, therefore, when bearing clearance must be allowed bearing in more severe working environment temperature change.
4.Due to the elastic modulus of the ceramic is higher than steel, when the stress is not easy to deformation, thus to improve work speed, and achieve higher precision
We proceed in 3 business lines:
