38.3. Roller Bearing

A roller bearing is composed of an inner ring, rollers, and an outer ring. The outer ring consists of several segments that are connected by beam forces, acting like a flexible body. The geometries is created from users input parameters. The roller bearing group has two kinds of contacts. One contact between balls and an inner ring is a Cylinder ToCCylinder Contact. The other contact between balls and an outer ring is a Cylinder In Cylinder Contact.
