Ceramic bearings in ZrO2 for shaft sizes from 3mm up to 50mm
The ZrO2 full ceramic ball bearings listed below are available as full complement (no cage) or with cages made from PEEK, PTFE or 316 stainless steel. These are non-magnetic, non-conductive and highly corrosion resistant to most chemicals although ZrO2 bearings are not recommended for prolonged contact with steam. Full complement bearings or those with a 316 stainless cage can be used up to 400°C while bearings with a PEEK or PTFE cage are rated up to 250°C. For temperatures below -70°C, PTFE or 316 stainless steel cages are preferred. See our ceramic bearing selection guide HERE
