Multi-objective optimization of spherical roller bearings based on fatigue and wear using evolutionary algorithm

Journal of King Saud University: Engineering Sciences, 2018
In Spherical Roller Bearings (SRBs) design the fatigue and wear lives are the most important factors. The fatigue life of bearing is connected to dynamic capacity (Cd) and wear life of bearing is linked with the elasto-hydrodynamic minimum film thickness

Finite Element Analysis for Cylindrical and Balling Bearings Under Static and Dynamic Loads A-review paper [PDF]

SVU-International Journal of Engineering Sciences and Applications
The ball bearing is a mechanical gearbox's most important component. It connects the roller to the inner and outer rings and hangs from the rotator to support the revolving parts. This technique allows for the transmission of both electricity and motion.
