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

Tolerance Design of Logarithmic Roller Profiles in Cylindrical Roller Bearings
Transactions of the Japan Society of Mechanical Engineers Series C, 2009 A logarithmic profile is essentially optimal crowning geometry for rolling machine elements such as bearing rollers and raceways. Although some design methods of the profile have been proposed, they do not refer to the tolerance of the geometry required in engineering applications and in production.
