Lovejoy 68514410208 Flexible Coupling Hub L050 Sintered Iron

Product Description

The LOVEJOY 68514410208 is a sintered iron flexible coupling hub designed for use in L050-series jaw-type flexible couplings. The hub accepts a minimum bore diameter of 0.25 inches (1/4 inch) and measures 1.08 inches in outside diameter with an overall length of 1.72 inches. Rated at 26.30 inch-pounds of torque, it is built to transmit rotational motion between shafts while accommodating minor misalignment. A complete coupling assembly requires two hubs and one spider insert, which are ordered separately. Mechanical contractors, industrial maintenance techs, and pump service professionals are the typical installers of this component.

This coupling hub is suited for light-duty power transmission applications including small pump drives, HVAC blower shaft connections, and general industrial equipment where compact, flexible coupling assemblies are specified. The L050 series designation identifies the coupling size and governs compatibility with matching hubs and spider elements. It is appropriate for both new installations and replacement service work where an L050 hub has reached end of service life.

Key Features

• Sintered iron construction for durability in mechanical drive applications
• Minimum bore diameter of 0.25 inches fits 1/4-inch shafts
• 1.08 inches outside diameter and 1.72 inches overall length for compact fitment
• Rated torque of 26.30 inch-pounds
• L050 series sizing ensures dimensional compatibility with matching L050 hubs and spider
• Two hubs plus one spider required for a complete coupling assembly

Compatibility

Designed for use within the L050-series jaw-type flexible coupling system. A complete coupling assembly requires two hubs (68514410208) and one L050 spider insert ordered separately. Verify bore diameter and coupling size code before installation.

Installation Notes

Installation is typically performed by a licensed millwright or mechanical technician. De-energize and lock out all connected equipment before disassembling or replacing coupling components. Ensure shaft and bore dimensions are verified prior to assembly, and confirm spider element durometer rating is appropriate for the application load. Follow applicable ANSI/ASME machinery guarding requirements when reassembling rotating equipment.
