The A 6A 4-21DF05016 is a double-flanged aluminum alloy timing belt pulley with 21 teeth, designed for use with 0.5-inch wide, 3/8-inch pitch timing belts. It has a 0.5-inch bore, a pitch diameter of 2.507 inches, an outer diameter of 2.507 inches, and a face width of 0.500 inch. The pulley features a hub length of 2.0 inches and includes two set screws for shaft attachment. All units are clear anodized and supplied with set screws at 90 degrees.
For power transmission applications, a belt and pulley drive system are one of the most common and cost-effective methods used to transfer motion in a drive system. synchronous timing belts, with their defined pattern and evenly spaced teeth, mate with matching timing belt pulleys and idlers to drive motion in precision equipment. When synchronization between shafts is not a priority, V- belts are an excellent alternative. V-belts ride in the groove of compatible V-belt pulleys and idlers. Flat belts find considerable usage in applications requiring small pulley diameters, high belt surface speeds, low noise levels, low weight, and inertia. Round belts or O-Rings are used with grooved pulleys. A cable drive system is another means of transmitting synchronous motion. Consisting of an extremely flexible cable and uniquely grooved pulleys, the Synchromesh Drive system offers design possibilities previously not achievable. Timing belt and cable accessories, belt tensioners and tension testers assist in the maintenance and operation of a belt drive system.
