Take-up ball bearing units for the SKF Food Line, consisting of an insert bearing based on a sealed deep groove ball bearing mounted in a composite housing. They are strong, yet lightweight, and chemically resistant to detergents and contaminants. This variant is intended for use in applications where the direction of rotation is alternating. It has an inner ring extended on one side and is locked by tightening a set screw on the inner ring, which makes it easy to mount.
