Ceramic ball bearings possess low density, high hardness and low friction coefficient especially for Si3N4 ceramic ball bearing with self-lubricating and good stiffness.

It is specifically made for rollers of high speed, precision and long life mixed ceramic ball bearing. Generally inner and outer rings are adopted with bearing steel(GCr15) or stainless steel(AISI440C) and we may choose ZrO2, Si3N4 or SiC material.

Miniature Bearing Description
FreeRun is a specialized manufacturer of Hybrid Ceramic Bearing. Full Complement ceramicbearings, Ceramic Balls.

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. )
