Experimental Study on the Skidding Damage of a Cylindrical Roller Bearing [PDF]

open access: yesMaterials, 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.

Dynamic Modeling and Behavior of Cylindrical Roller Bearings Considering Roller Skew and the Influence of Eccentric Load

open access: yesLubricants
At high speeds, skew and skid may frequently occur for the rollers in cylindrical roller bearings, especially when under eccentric load, as the uneven load distribution along the generatrix of the roller further aggravates this phenomenon. In this paper,

Design of an energy efficient cylindrical roller bearing

open access: yesMechanics 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.
