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.

Enclosed Conveyor Belt Tensioners
Prevent debris buildup, and thread damage—these tensioners have a totally enclosed adjusting screw. Tensioners mount to the sides of the conveyor and attach to the bearings that hold the pulley. Note: Two tensioners and two base-mount bearings (not included) are required.
Stainless steel tensioners are corrosion resistant.
