Ceramic Bearings

Ritbearing provides businesses with quality ceramic bearings for applications where standard materials pose problems.

Ceramic bearings offer several benefits such as increased stiffness and reduced friction. Ceramic is also advantageous for applications that can operate in corrosive, magnetic, and lubrication-free environments. Ceramic bearings are available in a variety of styles, including hybrid bearings with steel rings and ceramic balls to parts made with ceramic rings, balls, and retainers.

Ritbearing’s selection of ceramic bearings include:

  • Si3N4 Silicon Nitride
  • Al2O3 99.50% Alumina (Alumina Oxide)
  • ZrO2 Zirconium Oxide
  • Radial ball bearings (6000, 6200, and 6300 series)
  • Single row angular contact ball bearings (balls for 7000, 7200, and 7300 series)
  • Double row ball bearings (balls for 5200 series)
  • Thin section ball bearings


We’ve developed a network of manufacturers around the globe to provide our customers with a range of standard and custom bearing solutions. We work with the following manufacturers to help you invest in the quality ceramic bearings for your applications.

Features & Specs


Ceramic bearings come with many beneficial features:

  • Able to operate faster than conventional bearings
