SKF
Take-Up Ball Bearing Units
Take-up ball bearing units feature a Y-bearing in a housing designed to slide within a frame rail, allowing adjustment of shaft centre distance for belt or chain tensioning. SKF offers these in cast iron and composite, with open or closed housing ends. They are essential in belt conveyor head, tail, and tension stations, as well as bucket elevators and screw conveyors. The unit slides along guide rails; tensioning is applied via a screw mechanism. Sealed and pre-greased, these bearings operate reliably in dusty, dirty environments. SKF take-up units simplify maintenance by allowing fast belt changes and re-tensioning without component disassembly. They are globally interchangeable, reducing inventory requirements.

Integrated Slide
Housing edges fit standard frame rails for smooth positioning.
Easy Belt Tensioning
Screw adjustment moves the unit to maintain optimal tension.
Sealed and Protected
Y-bearing insert resists conveyor dust and moisture.
Robust Frame Compatibility
Cast iron frame slides handle harsh tensioning forces.
Regreasable Options
Extended service under contamination via grease nipple.
Open and Closed Housing Ends
Closed end blocks dust ingress on one side.
Take-Up Bearings in Belt Conveyor Tensioning
Proper belt tension prevents slippage and tracking errors. SKF take-up units allow operators to quickly adjust bearing position, extending belt and bearing life. In mining conveyors, these units endure heavy shock loads and abrasive dust; regreasable variants with labyrinth seals ensure longevity.
Selecting the Correct Take-Up Unit Size
The unit’s width across the slide rails, travel length, and load capacity must match the frame and tension requirement. SKF catalogues list all dimensions and load ratings, enabling straightforward selection during conveyor design or retrofit.
