This Bryant 51004 conveyor take-up tensioner has a 6" take-up stroke and a maximum holding force of 700 lb. It is suitable for use on conveyor belt systems and accommodates pillow block bearings with bores from 1/2 to 1". Its spring compression system compensates for expansion or contraction of the conveyor belt due to changes in temperature, shock caused by startup loads or sudden application of heavy loads, and slack caused by belt wear. The tensioner is constructed of powder-coated mild steel for strength, durability, and resistance to corrosion and has a retracted length of 10.375" and an expanded length of 16.375". It has a 0.625-11 Unified National Coarse (UNC) threaded Class 2A adjusting rod that allows for precise tension adjustment. The foot mounts for the tensioner have four 0.563" bolt holes spaced 2.625" apart vertically and 7.063" horizontally for a secure mount on the conveyor. This conveyor take-up tensioner is suitable for use on conveyor belt systems in a range of industrial settings.
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.
