BB4-Series / Heavy Duty Tensioners

The Brewer Heavy Duty Universal Drive Tensioners are specifically designed to support drives that utilize heavy engineering class chains and belts. This model is easily mounted to a machine frame with two bolts and thereby is adaptable for use with many different types of heavy conveying equipment. This heavy duty chain tensioner is vertically adjusted through the use of slots, which provides flexible and precision tensioning, as well as constant tensioning at all times. A two inch diameter shaft is set screwed into the hub. The stock length of the shaft is 13" and is also available in made-to-order lengths. On the "BB4," the adjusting slots are parallel to one another.
