Lovejoy 68514411729 Flexible Coupling Spider Urethane L110

Product Description

The LOVEJOY 68514411729 is a urethane flexible coupling spider designed for use in the L110 series jaw-type coupling system. This spider element fits between two mating hubs to transmit torque while accommodating minor shaft misalignment and dampening vibration. It accepts a maximum bore diameter of 1.625 inches and handles up to 1,188 inch-pounds of torque. The overall length is 4.25 inches and the outside diameter is 3.31 inches. Mechanical contractors, millwrights, and HVAC technicians install this component when assembling or servicing flexible shaft couplings on pumps, blowers, compressors, and similar rotating equipment.

This spider element is suited for light to medium industrial and commercial applications where flexible shaft couplings are required. Typical installations include close-coupled pump sets, fan drives, and motor-to-equipment connections in HVAC, plumbing, and light industrial systems. The urethane material provides good resistance to oils and moderate chemical exposure while offering flexibility under dynamic loading. Note that a complete coupling assembly requires two L110 hubs and one spider, which must be ordered separately.

Key Features

• Urethane construction provides vibration dampening and minor misalignment accommodation
• Rated torque capacity of 1,188 inch-pounds
• Maximum bore diameter of 1.625 inches for compatible L110 series hubs
• Outside diameter of 3.31 inches and overall length of 4.25 inches
• L110 series designation ensures dimensional compatibility with matching hubs
• Single spider element — two L110 hubs required for a complete coupling assembly

Compatibility

Designed for use in the LOVEJOY L110 series flexible jaw coupling system. A complete coupling requires two L110 series hubs and one spider. Hub components must be ordered separately.

Installation Notes

Installation is performed by qualified millwrights or mechanical technicians. Always de-energize and lock out the drive motor before removing or installing coupling components. Inspect hub bores and keyways for wear before fitting the new spider. Do not force the spider into misaligned hubs, as this can reduce service life and compromise torque transmission.
