Belt and chain tensioners reduce belt or chain slack that occurs in power transmission drive systems through normal operation. Slack reduces drive efficiency and decreases the life of drive components. Belt and chain tensioners help to maintain the correct drive belt or chain tension in a system by reducing this slack and transmitting drive torque uniformly, resulting in reduced noise and vibration and decreased sprocket, pulley, belt, or chain wear. They also reduce the risk of over-tensioning that exists with manual retensioning operations. Tensioners are available in three categories: fixed, adjustable, and automatic. Fixed tensioners must be remounted in order to alter the tension of a drive system. Manual tensioners require operators to adjust screws or reposition parts as belt or chain slack increases. Automatic tensioners apply tension as needed through the use of weight, springs, elastomers, or compressed air. Factors to consider in selecting a proper tensioner include drive power, speed, torque, load, operating cycles, and available mounting space. Belt and chain tensioners are used in industrial machinery, conveyor belts, automobiles, and other applications.

Brewer Machine & Gear manufactures tensioners, positioners, and idlers for the power transmission industry.  The company, founded in 1944, is headquartered in St. Louis, MO.
