Conveyor Belt Tensioners
A tensioner extends or retracts the conveyor pulley to adjust the tension on the conveyor belt. Mount to the sides of the conveyor and attach to the bearings that hold the pulley.
Stainless steel tensioners are corrosion resistant.
Note: Two tensioners and two bearings (sold separately) are required.
