CeramicSpeed SlipCoat - When Only the Cleanest Is Good Enough

We have received the question more than once – and in recent times more and more often: Can you make a bearing run without lubrication? This inquiry has become increasingly frequent, reflecting a growing interest in lubrication-free solutions. So far, our answer has been consistent: “All bearings can run without lubricant - but not for a very long time.”

The underlying demand has sparked our imagination and innovation. How can we provide a solution for applications where even the tiniest drop of oil could ruin products, disrupt processes, or contaminate sensitive environments?

One of our long-standing customers recently presented us with a specific challenge: to develop a completely “lubrication-free” bearing. In this case, absolutely no dripping or splattering of lubricant was acceptable, and the bearing needed to achieve a runtime of more than 3,000 hours of operation. Recognizing the importance and potential impact of such a solution, we immediately assigned this task to our team of in-house specialists.

Solution tested:

Ball bearing size 6202 
Stainless steel rings (AISI440C) 
Silicon Nitride rolling elements 
CeramicSpeed SlipCoat treatment

CeramicSpeed SlipCoat is available in any ball bearing configuration with short lead time!
