The Brief Introduction of Ceramic Ball Bearings:
Compared to steel, Ceramic ball Bearings have many specific
advantages. They offer superior corrosion and heat resistance,
higher dimensional stability, and lower density, which facilitate
high speed. Ceramics are superior to steel in heat and corrosion
resistance, and are lightweight and extremely hard as well.
Consequently, ceramic rolling bearings can be used in environments
where conventional steel bearings cannot. That is to say, the
superiority of these bearings makes it possible that they can be
applied in some special environments.
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
We are special in making Silicone Nitride Balls (Si3N4
Balls,Zicronia Balls (ZrO2 Balls),Sic Ceramic Balls , Aluminum
Oxside Valve (AI203) ceramic balls.
Compared with steel, ceramic materials are noted for their better
or particular characters, such as wear-resistance, corrosion
resistance, high temperature resistance, electrical insulation
(except SiC), non-magnetic, high strength, high rigidity, and low
specific gravity. These properties qualify them for replacing steel
to make bearings serve in conditions of higher speed, harsh
environment and less lube, and decrease wear, noise, vibration and
maintenance time of bearings, and eventually increase performance,
reliability and life of bearings.
