A 6H 3M42SF09508 is a 42-tooth, 5.08 mm pitch timing belt pulley with an 8 mm bore, designed for use with 9.5 mm wide belts. The pulley is molded from polycarbonate with fiberglass reinforcement and features an overmolded aluminum alloy Fairloc hub with a single flange. The bore tolerance is H9, and the hub screw insertion depth projects 20.6 mm with a 6.3 mm diameter screw hole for an M2.5 screw. The pulley has no webs due to having more than 21 grooves and measures 74 mm in length and 67.9 mm in pitch diameter.
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.
