A 6A61-20NF03110 is a 120-tooth timing belt pulley with a 0.3125-inch bore, designed for use with 0.3125-inch wide 40 D.P. belts. It is made of aluminum alloy with a clear anodized finish and features two set screws at 90 degrees for shaft retention. The pulley has a hub length of 0.3125 inches and a bore diameter of 0.3125 inches with a tolerance of +0.000 to -0.003 inch. Its pitch diameter is 3.120 inches, and outer diameter is 3.120 inches. The pulley has no flange and includes a hub for mounting.
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.
