I currently have an issue dealing with two cam plates separated by three ball bearings. We use grease as a lubricant however we are interested in using a coating lubricant. The total pressure between the plates is around 100,000psi. Xylan was tried, and was impressive,however did not quite meet the requirements we are looking for. Erdemir is another coating which we are looking into. Another possible solution to this, however, is changing the materials. We have tried carbide balls, chrome balls, ceramic balls, titanium balls, nickel coated plates and many other various possible fixes. I am wondering if perhaps anyone has a recommendation on this matter; a coating or different material combination that will withstand adhesive wear under extremely high loads. The current cam plates are D2 steel. The balls are 52100. The best possible solution involves only changing the ball bearings. The material selection for the cam plates is not very flexible.
