Bearing Material Overview: Ceramic

by | Jul 24, 2014 | Bearing Solutions

You’ve already heard about why you might choose steel bearings, so now let’s talk about the ceramic option.

CERAMIC BEARINGS

Bearings made with ceramic materials are usually classified as a hybrid because they commonly have a steel ring (outer race, inner race, and cage) with ceramic balls.

ADVANTAGES OF CERAMIC BEARINGS

Ceramic bearings are:

  • Able to operate faster than conventional bearings

  • More corrosion resistant

  • Rigid

  • Lighter weight (than most steel bearings)

  • Able to operate in high temperatures (Up to 1,800° F)

  • Nonconductive (can be used in electrical applications)

  • Effective in environments where lubrication may not be available (such as space applications)

DISADVANTAGES OF CERAMIC BEARINGS

  • Cost

Ceramic bearings are expensive, so many will seek out an alternative that we will discuss in our next post: plastic ball bearings.
