The A 6A 2-28XL08 is an aluminum alloy timing pulley with an 8-inch usable length and a 1/5 inch (5.08 mm) pitch, designed for synchronous belt drive systems. It has 28 teeth, a bore diameter of 1/2 inch (12.7 mm), and an outer diameter of 1.783 inches (45.3 mm). The pulley's outer diameter tolerance is +.004/-.000 inch (+0.10/0 mm), as specified for 32 to 62 grooves, though it applies to this part with 28 teeth based on the table's grouping and tolerance structure.
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.
