Product Details

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

Chain and belt life is increased as much as 30% by eliminating slap and vibration, while minimizing drive bearing and shaft wear
Self-adjusting
no periodic adjustments are necessary
Because of the elastomeric elements, the tensioner has the capacity to absorb shock loads and vibrations in the drive
Simple to mount, with only one bolt required to do so, and has 360° positioning flexibility
Maintenance-free
since the tensioner uses no metal-to-metal connections, no lubrication is required
provides silent operation
Dirt and grime will not affect operation, so it can be used indoors or out from -40 °F to 180 °F (-40 °C to 80 °C)

Check to be certain that the idler sprocket or pulley will still clear the space available between the base housing and the mounting hole
