Lovejoy 68514436058 Flexible Coupling Hub 5/8 in Bore

Product Description

The LOVEJOY 68514436058 is a flexible coupling hub designed for power transmission applications requiring reliable shaft-to-shaft connection with some tolerance for misalignment. Built from cast iron, this hub features a maximum bore diameter of 5/8 inches and a keyway measuring 3/16 inches wide by 3/32 inches deep. The outside diameter is 3-1/4 inches with an overall length of 2.88 inches. It is rated to a maximum of 7,600 RPM, making it suitable for moderate- to high-speed drive applications. Licensed mechanics and millwrights typically install these components in pump, blower, compressor, and HVAC equipment drive trains.

This flexible coupling hub fits into a wide range of industrial and commercial mechanical drive systems. It is well-suited for use in pump drives, fan assemblies, and compressor couplings where a keyed shaft connection is required. The cast iron construction handles the demands of continuous-duty rotating equipment. This hub corresponds to Lovejoy coupling size code 5J and is sold as a single unit.

Installation Notes

Installation should be performed by a qualified mechanic or millwright. Disconnect and lock out all power to the drive system before removing or installing any coupling component. Ensure the mating shaft, keyway, and spider element are inspected and in good condition before assembly. Consult applicable ANSI or equipment manufacturer alignment specifications to verify shaft alignment before returning the drive to service.
