The use of semi-solid lubricants is integral in the effort to protect against the frictional wear and scuffing between contacting surfaces in relative motion. The wide range of lubricating grease properties and their respective applications necessitates the diversification of existing screening methods. Established test methods and standards for lubricants can serve as the basis for screening greases based on their chemical properties, but has limited carry over to determining the behavior of greases in real-life operating conditions. The Translatory Oscillation Tribometer (SRV®) is a newly developed instrument that can conduct tests according to established test methods and standards, as well as application-oriented testing procedures, which can be used for evaluating friction, wear, and extreme pressure properties of lubricating greases. This poster will highlight application-oriented friction and wear tests through test scenarios involving the effect of wear particles on the lubricity of a lubricating grease, high temperature fretting behavior of industrial greases, and the simplified examination of rolling/sliding friction of high performance greases that can be used as a FE8/FE9 rolling bearing pre-screening test.
