Belt & Chain Tensioners (Beta Catalog)

The Lovejoy ROSTA tensioner is a universal product for use as an elastic spring device. Other applications beyond just belt and chain tensioning include pressing, cushioning, hold-down, guide rollers, belt scrapers, brake bars, cleaning brushes, limit stops, conveyor shock absorbers and much more. The actual idler sprocket, roller or pulley attached to the arm is not included. The Lovejoy ROSTA tensioner does include the idler bolt and nuts.

The arm has two holes which provide additional flexibility to generate two levels of force, “normal” and “hard,” through the arm. Most applications will be best suited to use the tensioner with the idler sprocket or pulley attached to the “normal” hole. However, if space restrictions cause the use of a smaller tensioner body, the “hard” setting can be utilized for approximately 25% more force.
