Zirconia ceramic bearings for shaft sizes from 0.125” up to 1.0”

Our imperial ZrO2 full ceramic ball bearings are manufactured from zirconium dioxide. These ZrO2 bearings are available as full complement or with a PEEK, PTFE or 316 stainless steel retainer. Zirconia bearings are non magnetic, non-conductive and are not affected by most chemicals although prolonged contact with hot water or steam can weaken the material. They can also withstand extreme temperatures depending on cage material. The full complement versions of these bearings can be used up to 400°C while those with a PEEK cage should be limited to 250°C. The standard radial play for these bearings is C3. See Bearing Material in our technical section for more information or contact us.

Imperial ZrO2 ceramic ball bearings are available open or with PEEK seals from stock in the UK. Some sizes are also available flanged. These ceramic bearings are generally used in specialist applications.
