Experimental Study on the Skidding Damage of a Cylindrical Roller Bearing [PDF]
Materials, 2020 As large-scale rotating machines develop toward high rotating speed and high power–weight ratio, skidding damage has become one of the major initial failure modes of cylindrical roller bearings. Therefore, understanding the skidding damage law is an effective way to ensure the safety of machines supported by cylindrical roller bearings.

Design of an energy efficient cylindrical roller bearing
Mechanics Based Design of Structures and Machines, 2022 In this study, the roller and ring raceway profiles of a cylindrical roller bearing (CRB) are designed. Starting from an initial design (i.e., an existing CRB, named NJ 309 EP4), it is intended to minimize the friction moment without sacrificing the fatigue life to have an energy efficient roller bearing.
