The ball bearing is composed of an inner ring, balls, and an outer ring. The outer ring consists of several segments, which are connected by a beam force, acting like a flexible body. The geometries are created from user input parameters. Contact between balls and an Inner/outer ring is a Sphere In Torus Contact.
