Silicon Carbide Bearings

Share This Page

Silicon carbide bearings offer many of the same benefits to their more readily available silicon nitride counterparts, including huge weight savings. However, silicon carbide delivers incredibly high corrosion-resistance, making it suitable for the world’s most toxic and chemically corrosive environments.


Similar to other ceramic materials, silicon carbide has a high hardness, low torque, and its bearings can run lubrication-free. However, this material is also electrically conductive, which can be used as a benefit in some applications.


These bearings are not as available as many of their other ceramic counterparts, however UNASIS-brand bearings can be readily supplied in popular metric and imperial sizes of deep groove and angular-contact ball bearings.
