The LOVEJOY 68514476852 is a flexible clamp hub designed for use in flexible shaft coupling assemblies. Part of the ADB series, this hub accepts a minimum bore diameter of 3/8 inches and features a 1.5-inch outside diameter with an overall length of 2.63 inches. Constructed from anodized aluminum, it provides corrosion resistance with reduced rotating mass. The clamp-style design secures the hub to the shaft without requiring keyways, making installation and removal straightforward. It is rated for up to 88 inch-pounds of torque, suited to light-to-medium duty motion control and mechanical power transmission applications.
This clamp hub is used wherever flexible couplings are needed to transmit torque between misaligned or offset shafts. Typical installation scenarios include HVAC fan and blower drives, pump drives, and general mechanical power transmission setups in both commercial and light industrial environments. Licensed mechanical technicians and millwrights commonly specify ADB-series hubs when servicing or replacing flexible coupling components in rotating equipment.
Designed as an OEM-style replacement hub for flexible shaft couplings in the LOVEJOY ADB series, coupling size code MADB7. Verify bore diameter, outside diameter, and overall length against the existing coupling before installation.
Installation is typically performed by a licensed millwright or mechanical technician. Disconnect and lock out all power to the drive system before removing or installing any coupling component. Ensure the shaft surface is clean and free of burrs before inserting into the bore. Tighten clamp fasteners evenly and confirm alignment of mating coupling halves before returning the system to service.
