Request Information

RunRight® RT F tensioners are designed for front mounting applications where access to back side or rear mounting surfaces is not possible. A single threaded hole is required to mount these tensioners. These tensioners include a special mounting screw and spacer bushing. They are manufactured with powder metal or cast iron housings, cast iron arms and inner square, come with the standard Tensys™ 10 rubber inserts, and can be used for applications operating within a -40° to 180°F (-40° to 80°C) temperature range.

Notes

Notes 

 N/A
  • The recommended angle of pretension is 20°. This provides the tensioner a maximum capability to absorb vibrations and shock loads, while also maintaining a range of motion to address the system’s belt or chain stretch.
  • Mounting accessories into the “Hard” Position results in approximately 25% higher tensioning force over the “normal” position.
  • Metric standard tensioner units all come with a mounting screw, but do not come with the sprocket idler bolt (which is supplied instead with RunRight metric idler sprockets).
