RunRight® RT SS tensioners are for use in the food and pharmaceutical industries. They are manufactured with cast stainless steel housings, arms and inner square. They 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 

  • 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).
