A technique for measuring roller speeds in cylindrical roller bearings using a modified laser anemometer has been developed. The technique described does not require any mechanical interference with the roller and cage geometries, and is suitable for high speed testing. The method has been used to measure roller speeds exceeding 15,000 rpm, in a standard 50 mm nominal bore, flanged inner track cylindrical roller bearing, under the conditions of light loads and lubricant starvation. Considerable cage and roller slip is detected only at radial loads less than 100 N, and the degree of slip present is found to be virtually independent of the low lubricant flow rates used in the investigation.
