Industrial Dodge 2-Groove QD Sheave, model 2A5.0B5.4-SDS, is a two-groove pulley designed for mounting on a compatible shaft with a QD bore. The two grooves accommodate two belts on a single sheave, enabling dual-belt drives in a compact footprint. It is identified by Dodge part numbers 455586 and 2A50B54SDS, reflecting its SDS-series designation. This QD sheave is used in belt-drive systems to transfer power between shafts in industrial equipment, providing straightforward belt alignment and replacement while distributing load across both belts when used with the appropriate hubs and belts.
