The A 6A 3-18NF03708 is an aluminum alloy timing belt pulley with 18 teeth, a 0.250-inch bore, and a 0.375-inch wide belt compatibility, featuring a hub and no flange. It has a pitch diameter of 1.146 inches, an outer diameter of 1.126 inches, and a hub length of 0.250 inches. The pulley uses two 90-degree set screws, each sized at #8-32, and is clear anodized. Its outer diameter tolerance is +.003/-.000. The part is designed for XL timing belt systems with a 1/5-inch pitch.
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.
