Martin Sprocket & Gear, Inc. E-2-3/16-QD Bushing

Martin Sprocket & Gear, Inc. E-2-3/16-QD Bushing is a Quick-Detach (QD) style bushing sized for a 2-3/16 in interface, designed to fit sprocket or gear hubs in power transmission assemblies. The E-2-3/16-QD designation identifies the exact bore/shaft size within Martin's QD bushing family, enabling a standardized, interchangeable component for drive trains that use QD mounting. This 2-3/16 in bushing acts as the hub-to-shaft connector in systems where a removable, serviceable connection between a shaft and a sprocket or gear is required, allowing removal for maintenance without swapping entire hubs. Manufactured by Martin Sprocket & Gear, this bushing provides a precise fit for compatible hubs and shafts that specify the E-2-3/16 size, supporting proper alignment and consistent performance in industrial drive systems that rely on QD mounting specifications.
