Abstract
This paper examines surface roughness effects and the inaccuracy introduced by changes in roughness resulting from normal run-in. While factors such as the ‘Oil Film Thickness to Composite Surface Roughness ratio’, Lambda, are being used, their reliability is dependent on the accuracy of the input data. Studies were conducted on cylindrical roller bearings (40 mm bore) at two calculated Lambda levels, 1.5 and 0.04, to evaluate changes in surface texture during short running time increments. The conclusion of the study offers recommendations for improving the methods used to predict bearing fatigue life.
