Measurement of Roller Speed in a Cylindrical Roller Bearing Using a Laser Anemometer [PDF]
, 1978 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 ...

Squealing of cylindrical roller bearings.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1990 Large-sized cylindrical roller bearings often emit high level squealing in grease lubrication. There are many studies on the squealing sound of the cylindrical roller bearing, however, comprehension of this sound is far from complete. We have measured sound pressure, acceleration of outer race, the roller/race slip behavior, and sound intensity. A main
