Abstract
Very often, the service life of grease lubricated rolling bearings is determined by the so called “grease life”. This can be tested on R0F test rigs, which have been available for this since more than 40 years. Recently, this technology has been updated and is now called R0F+. The R0F+ can be used as a reference for grease life/relubrication intervals or as a research tool. In this paper a description of the test rig and the test methodology will be given. Also the reliability of the rig will be described by means of a comparison of six test rigs. The test philosophy will be illustrated using the so-called “traffic light” and the “grease performance factor” concepts. The R0F+ goes beyond “standard grease life testing”. The rig is a most valuable tool in grease lubrication research due to its flexibility in varying load, speed, temperature and bearing type. This will be illustrated with some examples.
