Take-up ball bearing units for 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. Typically mounted in take-up frames, the unit has an inner ring extended on both sides and is locked by tightening a set screw on the inner ring, which makes it easy to mount.
