Key Facts
- Poor lubrication (thin films/dilution): these bearings can withstand poor lubrication conditions, such as very thin oil films or non-standard lubricants (e.g., refrigerant in chillers). Their silicon nitride rolling elements help maintain performance and extend bearing life even when lubrication is suboptimal, with tests showing up to four times longer life compared to all steel bearings.
- Electric erosion: The silicon nitride rolling elements in SKF Hybrid ceramic bearings provide electrical insulation, preventing electrical currents from passing through the bearing. This eliminates the risk of electrical erosion, which can damage bearings in electric motors and generators, leading to improved reliability and reduced unplanned maintenance.
- Grease life: SKF Hybrid ceramic bearings minimize friction and wear, which extends grease life by up to eight times when used with high-performance lubricants. This results in fewer maintenance interruptions, lower lubricant consumption, and more environmentally responsible operations.

Product information
SKF Hybrid ceramic bearings combine steel rings with silicon nitride (ceramic) rolling elements. This advanced design provides electrical insulation, high speed capability, improved machine accuracy, extended service life, and superior wear resistance.
These bearings are engineered to meet the demands of modern industrial applications, especially in environments facing electrification, automation, and sustainability challenges.
They are dimensionally interchangeable with standard all-steel bearings and offer a more sustainable, energy-efficient solution with reduced maintenance needs.
