SKF
Take-Up Roller Bearing Units
Take-up roller bearing units combine a heavy-duty spherical or tapered roller bearing with a slide-frame housing for belt or chain tensioning in large conveyors, bucket elevators, and material handling systems. Housings are fabricated steel or robust cast iron with machined slide rails. SKF’s take-up roller bearing units are built for high-load tensioning in mining, quarrying, and cement plants, where belt tension is measured in tonnes. The bearing is often regreasable and protected by multiple sealing stages against abrasive dust and water. Their robust construction resists the frame deflection that occurs under extreme tension forces. SKF provides guidance on maximum tension loads and slide travel for proper sizing.

Heavy-Duty Slide Rails
Machined for smooth movement under extreme belt tension.
Spherical Roller or Tapered Roller Bearings
High dynamic loads and shock resistance.
Multiple Seal Stages
Labyrinth plus lip seals exclude abrasive bulk material fines.
Regreasable for Extended Life
Purgeable cavities eject contaminants.
Robust Steel Housings
Welded and machined for strength and precision.
Standard Rail Widths
Drop-in compatibility with common conveyor frame sections.
Take-Up Roller Units in Longwall Mining Conveyors
Underground mining conveyors experience extreme tension changes during start-up. SKF’s take-up units accommodate dynamic belt stretch while maintaining bearing seal integrity under falling coal and rock dust. Their reliability is critical for continuous production.
Tension Mechanism Integration
Tensioning screws or hydraulic cylinders attach to the take-up frame. SKF’s housing strength data ensures that the unit can withstand the full tensioning force without deformation, preserving alignment and seal function.
