Lovejoy 68514412265 Flexible Spider Coupling Insert L190

Product Description

The LOVEJOY 68514412265 is a Hytrel flexible spider insert designed for use in jaw-style flexible couplings. This spider element fits between two coupling hubs to transmit torque while absorbing shock, dampening vibration, and accommodating minor shaft misalignment. It carries a rated torque of 4,680 inch-pounds and is manufactured from Hytrel, a polyester elastomer known for resistance to oil, heat, and fatigue under cyclic loading. The part measures 4.5 inches in outside diameter and 4.88 inches in overall length. It is sold as a single spider insert; two hubs must be ordered separately to complete the coupling assembly.

This spider insert belongs to the L190 coupling series and is used in power transmission applications across industrial, HVAC, pump, and general machinery installations. It is suited for both new coupling assemblies and field replacement of worn or damaged spider elements. Hytrel spiders offer a balance of flexibility and torque capacity, making them appropriate for moderate-duty drive applications where some shock loading or misalignment is present. One spider and two compatible L190-series hubs are required for a complete coupling.

Key Features

• Hytrel polyester elastomer construction resists oil, heat, and fatigue
• Rated torque of 4,680 inch-pounds (529 Newton-meters)
• 4.5 inches outside diameter, 4.88 inches overall length
• L190 series coupling size code for straightforward hub matching
• Absorbs shock and dampens vibration in jaw-style flexible couplings
• Sold individually — two L190 hubs required to complete the assembly

Compatibility

Designed for use with L190-series jaw coupling hubs. Two L190 hubs and one spider are required for a complete coupling assembly. Confirm hub bore, series, and torque rating before ordering.

Installation Notes

Installation is typically performed by a millwright or mechanical technician. Disconnect and lock out all power to the drive before disassembling the coupling. Inspect hub bores, keyways, and set screws for wear before installing the new spider. Do not operate the coupling above the rated torque or outside the angular and parallel misalignment limits specified by the hub manufacturer.
