The A 6AS9M3724021S is a single-action chain tensioner with a 21-tooth steel sprocket and a high-tensile die-cast aluminum alloy arm, designed to maintain constant tension for 3/8" pitch roller chains. It has a maximum operating temperature of 100°C (212°F). Dimensions include an overall length of 119 mm (4.69 in), a mount hole diameter of 10 mm (M10), and a sprocket pitch diameter of 5.20 mm. The tensioner features anti-rotation holes and a ball bearing sprocket, with a minimum chain load capacity of 80 N (18 lbf) and a maximum of 180 N (40 lbf).
Chain and sprocket drives are often used where positive synchronization between shafts and transmission of substantial torque are required. They are one of the more frequently used methods of power transmission, providing greater power than belts. Highly efficient, a single chain can drive several shafts and is used for both long and short distances. Adverse conditions, such as temperature and environment, do not affect their running. Other advantages include compact size and low maintenance costs. Chain drives are found in a wide range of power transmission applications, including bicycles, agricultural machinery, machine tools, conveyors, business machines, electronic or electro-mechanical devices, etc.
