Full ceramic bearings

These full ceramic bearings, not to be confused with hybrid ceramic bearings, can be made from Zirconium Dioxide (ZrO2) or Silicon Nitride (Si3N4) and can perform in temperatures ranging from -200 degrees Celsius to 800 degrees Celsius. This means businesses operating in harsh environments can now use bearings that are fit for purpose.

"As these bearings can face extreme environments both in terms of temperature and pH level, they have positive implications for a range of industries," said Chris Johnson, managing director at SMB Bearings. "An order has even come in for use in a vehicle on Mars, a planet that can face temperatures as low as 125˚C. The pharmaceutical industry is another good example of where these bearings can be used. With strong acids and alkalis used regularly, there is a great need for highly corrosion resistant bearings.

SMB Bearings' ceramic bearings are available as full complement (no cage) or with a cage made from PEEK or PTFE. The company also provides a bespoke relubrication service.
