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

The optimum angle of pretension is 20Âș the maximum angle is 30Âș.
At 20Âș the tensioner has maximum capability to absorb vibrations and shock loads, and still have enough arc motion to automatically take up belt or chain stretch.
