The Unmarked 3-5V10.9-SF sheave pulley is a 3-groove, 5V belt pulley with a 10.9 in pitch diameter, designed for bushing-mounted installation using a SF taper-lock bushing. It transfers rotational power between shafts in industrial power transmission systems via V-belt drives and complies with ARPM/RMA V-belt standards for reliable torque transmission. Common applications include conveyors, HVAC equipment, air compressors, centrifugal pumps, and other manufacturing machinery where precise speed control and dependable belt drive performance are essential. The pulley can be manufactured from cast iron or steel depending on the application.
