An Optimum Design of Crowned Cylindrical Roller Bearings

Apr 15, 2009· The long fatigue life is the one of the most important criterion for the design of rolling bearings, however, due to complex and diverse internal geometries, each type of rolling bearings require a different design formulation. To increase the life of cylindrical roller bearings, the profile (or the crowning) of the roller plays an important role.

All about Cylindrical Roller Bearings

Jan 29, 2015· All about Cylindrical Roller Bearings. Rolling element bearings are perhaps the most common form of bearing and operate by carrying a load by placing rolling elements, such as balls or rollers, in between two rings, known as races. A common type of rolling bearing is the cylindrical roller bearing, which, as their name implies, uses cylinders
