The A 6A51M021DF0304 is a 21-tooth, 2 mm pitch GT®2 timing belt pulley with a 4 mm bore, double flange, and hub, machined from aluminum alloy and finished with clear anodizing. It is designed for use with 3 mm wide GT®2, GT®3, or FHT®-2 timing belts and features one set screw for shaft locking. The pulley has a pitch diameter of 13.4 mm, an outside diameter of 18 mm, an overall length of 12.3 mm, and a hub projection of 9.9 mm. The set screw is M2.5. The body diameter is 12.1 mm, and the flange height is 2.8 mm.
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.
