The Brewer Heavy Duty Universal Drive Tensioners are specifically designed to support drives which utilize heavy engineering class chains and belts. All four models are easily mounted to a machine frame with two bolts and thereby are adaptable for use with many different types of heavy conveying equipment. They are vertically adjusted through the use of slots. This vertical adjustment feature 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. The shaft on the "BB1" model is aligned to the centerline of the adjusting slots, while the shaft on the "BB2" model is at a 90º angle to the centerline of the adjusting slots. The adjusting slots are on either side of the shaft on the "BB3". On the "BB4", the adjusting slots are parallel to one another.
