T-Series & MSL / Automatic Tensioning



T-Series/Spring Loaded

 
The Universal Drive Tensioner Spring loaded T-series incorporates an adjusting slot for control tensioning and a serrated arm, permitting tensioning at any point on a 360º arc.
The "T" Series tensioner has a spring for a constant tension which is more practical for pulsating loads. The base is more practical for pulsating loads. The base is made of high-grade semi-steel casting, incorporating a needle bearing and ball bearing to eliminate binding on over-hung loads. A precision cut gear and rack combined with a spring enables the arm to work 90º in either direction.

The standard model will support a 22# load at the idler shaft center. If more capacity is desired, a heavier spring is available to support up to 44# which pivots 45º in either direction.

MSL / Spring Loaded

The MSL Tensioner, with a compression spring located in the base casting, is designed for drives with shock and pulsating loads. For every 28 pounds of force applied the spring will compress 1 inch. The tensioner will "cushion" and protect the drive from the damage caused by shock and pulsation. The idler head casting rotates 360 degrees and vertical adjustment is accomplished through 4 slots.
