  • Full ceramic bearings made from silicon nitride - SMB

    Our silicon nitride bearings are supplied with a C3 loose radial play as standard. For temperatures below -70°C it is worth considering PTFE or 316 stainless steel cages due to their better low temperature performance. For an overview of the pros and cons of silicon nitride bearings, you can click HERE to see our ceramic bearing selection guide.
