Lovejoy 68514477392 Flexible Clamp Hub Anodized Aluminum

Product Description

The LOVEJOY 68514477392 is a clamp-style flexible coupling hub designed for light-duty power transmission applications. Machined from anodized aluminum, this hub accepts a minimum bore diameter of 1/8 inch and measures 0.75 inches in outside diameter with an overall length of 0.9 inches. It belongs to the MOL series and is rated at 5 in/lb of torque. The clamp hub design allows for quick shaft engagement and secure clamping without requiring a keyway, making installation straightforward for maintenance technicians and mechanical contractors working on small motor, pump, or actuator assemblies.

This hub is suited for residential and light commercial mechanical systems where compact, low-torque flexible couplings are required. Typical applications include small HVAC actuators, damper drives, pump shafts, and similar equipment where shaft misalignment compensation is needed. The EC075 coupling size code identifies the hub as part of a matched coupling set within the MOL series lineup.

Key Features

• Clamp-style hub design for tool-accessible shaft attachment without a keyway
• Anodized aluminum construction for corrosion resistance and reduced rotating mass
• Compact 0.9-inch overall length fits tight shaft-to-shaft clearances
• Rated at 5 in/lb torque for light-duty power transmission
• EC075 coupling size code for matched MOL series pairing
• Minimum bore diameter of 1/8 inch for small-diameter shafts

Compatibility

Designed as an OEM-style replacement or new-installation hub within the LOVEJOY MOL series flexible coupling system, coupling size code EC075. Consult the MOL series selection guide to confirm mating spider and opposing hub compatibility for your specific bore and torque requirements.

Installation Notes

Installation should be performed by a qualified mechanical technician. De-energize all connected motors and actuators and lockout/tagout the circuit before handling any coupling components. Ensure the shaft and bore surfaces are clean and free of burrs before seating the hub, then tighten the clamp fastener to secure. Do not exceed the rated torque capacity of 5 in/lb to avoid hub slippage or damage to the coupling spider.
