Abstract
Computer simulations of a high-speed cylindrical roller bearing, as obtained by the computer code ADORE, are used to correlate bearing performance to the frictional behavior at the roller/race and cage contacts. It is shown that an optimum traction-slip relation at the roller/race contacts may be determined to produce minimum race wear and heat generation in the bearing. Unlike the well defined circular cage mass center whirl orbits commonly seen in ball bearings, no significant cage whirl was found in a lightly loaded cylindrical roller bearing over the range of frictional parameters considered.
