Lovejoy 68514410420 Flexible Coupling Hub L050 Sintered Iron

Product Description

The LOVEJOY 68514410420 is a flexible coupling hub in the L050 series, machined from sintered iron for reliable torque transmission in light-duty mechanical drive applications. The hub accepts a minimum bore diameter of 0.25 inches (1/4 inch) and measures 1.36 inches in outside diameter with an overall length of 2 inches. Rated at 43.20 in-lb of torque, it is designed to mate with a corresponding spider element to form a complete jaw-style flexible coupling. Mechanical technicians and millwrights install this hub when aligning motor-to-pump, motor-to-gearbox, or similar shaft couplings in HVAC equipment, pumps, and light industrial machinery.

The L050 series hub is suited for residential and commercial mechanical systems where vibration dampening and minor misalignment correction are required between a driver and driven shaft. A complete coupling assembly requires two hubs and one spider element ordered separately. This hub is appropriate for applications where sintered iron construction provides adequate strength and the compact L050 size fits space-constrained drive arrangements.

Key Features

• Sintered iron construction provides consistent dimensional tolerances and adequate strength for light-duty torque loads
• Rated torque of 43.20 in-lb suitable for small motor and pump drive applications
• Minimum bore diameter of 0.25 inches accommodates 1/4 inch shafts
• 1.36 inch outside diameter and 2 inch overall length fit compact drive arrangements
• L050 series sizing for straightforward hub-to-spider compatibility within the same product family
• Sold individually — two hubs and one spider required to complete the coupling assembly

Compatibility

Designed as an OEM-style replacement or new-installation hub for jaw-style flexible coupling assemblies requiring L050 series components. A complete coupling requires two LOVEJOY L050 series hubs and one L050 spider element.

Installation Notes

Installation is performed by a qualified millwright or mechanical technician. Disconnect and lock out all power to the drive system before removing or installing coupling components. Ensure shaft and bore surfaces are clean and free of burrs before pressing or keying the hub onto the shaft. Verify shaft alignment to manufacturer tolerances after assembly before returning the drive to service.
