Martin Sprocket Gear M 3-15/16 QD Bushing Type M is a Quick-Disconnect (QD) bushing used to mount sprockets or pulleys to a shaft in power transmission systems. It features a 3-15/16 in bore and is part of Martin's M-series QD bushings, designed to fit compatible hubs and sprockets that accept the Type M sizing. This Type M bushing supports removable, on-shaft mounting in industrial drive assemblies that rely on a standard M-series interface.
