Lovejoy 68514411717 Flexible Coupling Spider Hytrel L110

Product Description

The LOVEJOY 68514411717 is a flexible jaw coupling spider element made from Hytrel, a thermoplastic elastomer known for durability and resistance to oils, heat, and flex fatigue. This spider fits within the L110 series jaw coupling system and serves as the drive element seated between two opposing hubs. It measures 4.25 inches overall length and 3.31 inches outside diameter. The spider absorbs torsional shock and dampens vibration between coupled shafts. It is rated for up to 2,268 inch-pounds of torque. Maintenance technicians, millwrights, and mechanical contractors install these elements during coupling service or scheduled preventive maintenance on rotating equipment.

This spider element is used in L110 series jaw couplings found in light industrial and commercial applications such as pump drives, fan assemblies, compressors, and conveyor systems. To complete a functional coupling assembly, two L110 hubs and one spider are required. The Hytrel material makes this spider appropriate for applications involving moderate shock loads, temperature variation, and exposure to common industrial fluids. It is a direct replacement spider for any L110 series jaw coupling requiring a new elastomeric element.

Key Features

• Hytrel elastomeric material provides resistance to oils, heat, and repeated flex cycles
• Rated for 2,268 inch-pounds of torque in L110 series couplings
• 3.31 inches outside diameter and 4.25 inches overall length for L110 series fitment
• Absorbs torsional shock and dampens vibration between drive and driven shafts
• One spider plus two separately ordered hubs completes the coupling assembly

Compatibility

Designed for use with LOVEJOY L110 series jaw coupling hubs. Two L110 hubs must be ordered separately to complete the coupling assembly. Consult the L110 series coupling specification sheet to confirm shaft bore range and hub selection before ordering.

Installation Notes

Installation is performed by millwrights or qualified mechanical technicians. De-energize and lock out the drive equipment before disassembling the coupling. Remove both hubs from the shaft ends, replace the worn spider element, and reassemble with the hubs properly seated against the spider lobes. Verify shaft alignment to manufacturer tolerances before returning the equipment to service, as misalignment accelerates spider wear.
