Si3N4 ceramic bearings for shaft sizes from 3mm up to 50mmSMB ceramic bearing in Si3N4

The ceramic ball bearings shown in the dimension table below have rings and balls made from silicon nitride (Si3N4). These silicon nitride bearings are available from stock in the UK without a cage (full complement) or with cages made from PEEK. We can also offer our ceramic bearings with PTFE or 316 stainless steel cages. These are non magnetic, non-conductive and extremely corrosion resistant to most chemicals although not suitable for shock/impact loads due to the more brittle nature of the material. They can also withstand extreme temperatures. Silicon nitride full complement bearings can be used up to 800°C while bearings with a PEEK cage can cope with temperatures of up to 250°C. PTFE and 316 stainless steel cages are used for temperatures down to approximately -200°C. There is more information on silicon nitride in our technical section or you can contact us.


Our silicon nitride ceramic bearings are available open or with PEEK seals. Some sizes may also be available flanged. Si3N4 ceramic bearings are generally used in specialist applications for their high temperature capabilities, excellent corrosion resistance or non-magnetic properties. Other sizes are available on request.
