  • Conveyor Belt Tensioners McMaster-Carr

    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. For technical drawings and 3-D models, click on a part number.

  • Conveyor Belt Tensioning Techniques

    Use only the lowest tension needed to engage the drive sprockets properly. All conveyor circuits should have provision for adjusting belt tension and to facilitate installation of the belt. If excess belt length accumulates loosely on the return path the belt may slip or jump off the drive sprockets. Take-up of slack can be done in several ways:
