Rexnord 50RN-HUB-HQD Hub

Rexnord 50RN-HUB-HQD is a 50-series Quick Disconnect Bushing (HQD) hub, steel construction, designed to accept Rexnord HQD elastomeric couplings. It is bored for an E-size bushing and has an outside barrel diameter of 8.130 inches, aligning with the HQD interface used on Rexnord drives. Built for inch hardware configurations, this hub pairs with E-bushing components to form HQD assemblies for power transmission in industrial equipment. The 50RN-HUB-HQD hub is intended to be used with the corresponding E bushing to connect shafts in conveyors, pumps, and other industrial drive trains, enabling straightforward replacement of bushings without removing the entire coupling set and preserving shaft alignment.
