Idler Shafts must be ordered seperately. Click here for shaft selection.

single adjusting tensioner (shaft mount)

 

The Single Adjusting Tensioner can be mounted on any point of a shaft or stud. This tensioner permits controlled tensioning at any point of the 360 arc. The split at the base of the arm allows for fast adjustment and tight clamping on the shaft. The SAT series tensioner should be used when a frame member is not present and a bolt-on tensioner is not an option.

spring loaded tensioner

The SLT Tensioner Series uses a compression spring for automatic tensioning, the spring will compress 1 inch for every 28 pounds of force with a max. travel of 3 inches. This tensioner will provide constant tension that will protect the drive from damage caused by shock and pulsation. The head rotates 360 and the base has additional vertical adjusting slots.
