A 6A 3-25NF03708 is an aluminum alloy timing pulley with 25 teeth, a 0.250 inch bore, and a 0.375 inch wide belt compatibility, featuring a clear anodized finish and no flange. It has a pitch diameter of 1.592 inches, an outside diameter of 1.572 inches, a hub length of 0.250 inches, and a hub projection of 3/8 inch. The pulley has two set screws at 90 degrees and uses an #8-32 screw. The O.D. tolerance for 25 grooves is +.003/-.000.
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.
