Lovejoy 68514410216 Flexible Coupling Hub L050 Sintered Iron

Product Description

The LOVEJOY 68514410216 is a flexible coupling hub in the L050 series, designed to connect rotating shafts in mechanical drive systems. Made from sintered iron, this hub accepts a minimum bore of 0.25 inches and a maximum bore of 0.3937 inches (10.00 mm), with an outside diameter of 1.08 inches and an overall length of 1.72 inches. It is rated for 26.30 in/lb (3.00 N/m) of torque. Coupling hubs like this one are installed by millwrights, maintenance mechanics, and industrial technicians working on pump, motor, and shaft alignment applications.

This hub is used in light-duty industrial and mechanical drive applications where a flexible jaw-type coupling is needed to transmit torque between two shafts while accommodating minor misalignment. The L050 series hub pairs with a matching hub and a spider insert to form a complete coupling assembly. Note that a complete coupling requires two hubs and one spider, sold separately. Typical installation environments include pumps, small motors, conveyors, and similar rotating equipment in commercial and light industrial settings.

Key Features

• Sintered iron construction for durability in mechanical drive applications
• Accepts bore diameters from 0.25 inches up to 0.3937 inches (10.00 mm)
• Outside diameter of 1.08 inches with an overall length of 1.72 inches
• Torque rating of 26.30 in/lb (3.00 N/m)

Compatibility

Designed for use in the LOVEJOY L050 series flexible jaw coupling system. A complete coupling assembly requires two L050 series hubs and one compatible L050 spider insert. Compatible spider and hub combinations should be verified against the L050 series coupling specifications.

Installation Notes

Installation is typically performed by a qualified millwright or maintenance mechanic. Before installation, de-energize and lock out the motor or drive equipment per OSHA lockout/tagout procedures. Ensure shaft alignment meets the tolerance requirements of the L050 series before final assembly. Do not overtighten set screws or fasteners beyond the coupling manufacturer specifications; refer to the LOVEJOY L050 installation sheet supplied with the product.
