- 18 in Size
- Chain/Belt Tensioner Type
description
- 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.
applications
- Belt and chain tensioning
- Pressing
- Cushioning
- Hold-down
- Guide rollers
- Belt scrapers
- Brake bars
- Cleaning brushes
- Conveyor shock absorbers
- Limit stops
features
- 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
- Note: Idlers, sprockets and pulley accessories are available online
