Ball bearing take-up units are used where shaft adjustment and belt-tightening devices are required, as on conveyor applications. Both types of take-up units incorporate self-aligning B type wide inner ring ball bearings with self-locking collars.
The RTU uses a G-KRRB (R-Seal) type wide inner ring bearing.
These units provide very compact, efficient supports for adjustable shafts and conveyor take-up pulleys.
These units are factory lubricated, but a grease fitting is provided for relubrication if required.
