Tensioner Arm For Chain and Belt Tensioner

• Idler sprockets tensioner arms work to ensure Chain Belt drives run under consistent and uniform tension, negating Chain Belt stretch.

All About The Elastomeric Tensioner's Benefits

• A one nut mounting system, which allows for 360° rotation.
• Can be pre-tensioned by up to 30°, this means that as the chain or belt stretches, the tensioner automatically takes up the slack as the elastomeric elements automatically adjust the tension of the drive.
• Chain and Belt life is increased by as much as 30%.
• Elastomeric parts absorb vibrations and shock loading.
• Maintenance Free - no metal on metal parts, lubrication-free.
• Impervious to dust and dirt, temperature -40° to +80°.
• Two holes are provided on the arm, allowing two different levels of force to be generated: "normal" and "hard".
• The "hard" setting deploys approximately 25% more force.
