Adjust-Screw Tensioner, 1-B

Adjusto-Screw Tensioner


The Murray Adjusto-Screw, which is “slack-side” mounted, uses a screw to provide precise, easily-adjustable tension. The screw adjustment enables the user to set the precise tension necessary to provide maximum life for the sprocket and chain or belt. This is especially advantageous with heavy chains where slack is normally taken up by hand while making the adjustment. With the Adjusto-Screw, chain take-up and tension settings are both controlled with the screw. Adjusto-screw tensioners are useful on vertical drives, preventing lower sprocket disengagement. Constructed of structural steel (many competitive brands use cast iron), this patented tensioner is available in a wide range of capacities capable of handling up to RC 240 roller chain.

Many drive systems are enclosed, for safety reasons. With conventional tensioners, the enclosure must be removed for drive adjustment. With Adjusto-Screw tensioner, tension adjustments can often be made through a hole in the enclosure adjacent the head of the screw, substantially reducing costly maintenance and drive down-time. The screw is adjustable from either end of the tensioner.

All Murray tensioners improve drive performance by eliminating whipping and slipping of loose drive chains and belts. They reduce vibration, noise and maintenance and provide additional life to drive components.
