ZrO2 ceramic bearings for shaft sizes from 3mm up to 50mmSMB ceramic bearing in ZrO2

The full ceramic ball bearings listed below are supplied with rings and balls made from zirconium dioxide (ZrO2). These zirconia bearings 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 can cope with temperatures of up to 250°C. For temperatures below -70°C, PTFE or 316 stainless steel cages are preferred. Standard radial play for full ceramic bearings is C3 but other clearances can be supplied to order.

SMB ceramic bearings are available from stock in the UK open or with PEEK seals. Some sizes may also be available flanged. ZrO2 ceramic bearings are generally used for their extreme temperature capabilities, excellent corrosion resistance or non-magnetic properties. Other sizes can be supplied on request.
