A comparative numerical quasi-static analysis has been made between an angular steel ball bearing and an angular hybrid ball bearing, having the same external and internal geometry (7007C series). Though a quasi-static program offers only a solution independent of time regarding the contact forces, it is useful to appreciate the load distribution and the fatigue life …

Rolling - Wikipedia

Rolling is a type of motion that coines rotation (commonly, of an axially symmetric object) and translation of that object with respect to a surface (either one or the other moves), such that, if ideal conditions exist, the two are in contact with each other without sliding. Rolling where there is no sliding is referred to as pure rolling
