Ceramic Bearings

Increasingly at the forefront of specialist bearing technology, ceramic bearings provide a practical, high-performance option to meet the demands of new developments. With high-temperature performance and corrosion-resistance, these bearings can operate without lubrication with some of the lowest possible torque values. This helps to increase performance and reduce manufacturing costs.

Available in popular metric and imperial sizes, our ceramic bearings can also be manufactured to custom sizes, with a fully tailored design to meet your specific requirements. From custom cage design and manufacture in a range of exotic materials, to ball selection with a selection of internal clearance options (C3-C5), we have the expertise needed to ensure that every aspect of your bearing is perfect for its application.

Explore just some of our options below and find out the advantages each material offers. To discuss any of these in more detail, including tailored solutions and technical support, please contact our bearing engineers today.
 

Advantages

Lubrication Free

As ceramic is a non-ferrous material, individual components do not micro-weld together, allowing the bearing to run without lubrication.

Corrosion Resistance

Unlike bearing steel, ceramic does not corrode upon exposure to water or other hazardous chemicals. Instead, they exhibit an extraordinary resistance to corrosion, allowing them to work more effectively in otherwise difficult environments.

Electrical Insulators

With a distinct lack of free electrons, the atomic makeup of most ceramics make it an incredible electrical insulator, and resistant to electric flow. 

High Hardness

The majority of ceramics score between 70 and 90 on the Rockwell hardness scale (HRC).

Extreme Temperatures

The energy needed to impact the bond length in ceramics is much higher than traditional bearing steel. This low thermal expansion means they are typically more stable at higher temperatures, enabling them to perform in temperatures of both extremes. 

High Elastic Modulus

The high relative elastic modulus of ceramic bearings make them resistant to shape change with applied loads, improving the wear-resistance characteristics.

Low Density

While zirconia has a similar mass to stainless steel, silicon nitride and silicon carbide are among the lightest ceramic materials. This low density can significantly reduce assembly weight, making them ideal for more demanding applications.

Non-Magnetic

Ceramics are both non-metallic and non-ferrous, eliminating any magnetism in their system.
