Lovejoy 68514411486 Flexible Coupling Spider Hytrel L100

Product Description

The LOVEJOY 68514411486 is a flexible coupling spider element made from Hytrel, a thermoplastic elastomer known for its resilience and resistance to flexing fatigue. This spider insert fits within the L100 series jaw-style coupling and serves as the flexible intermediate element between two coupling hubs. It transmits torque while absorbing shock, damping vibration, and accommodating minor shaft misalignment. The part measures 3.5 inches overall length and 2.54 inches outside diameter, with a rated torque capacity of 1,134 inch-pounds. It is installed by licensed millwrights, industrial maintenance technicians, and mechanical contractors working on rotating equipment drives.

This spider element is used in L100 series jaw couplings across a wide range of industrial and mechanical drive applications including pumps, compressors, fans, and conveyor drives. It is suited for both light commercial and industrial equipment where flexible coupling connections are required. One spider element and two separate hubs are required to assemble a complete L100 coupling. The hubs must be ordered separately — this listing is for the spider element only.

Key Features

• Hytrel material provides flexibility, shock absorption, and fatigue resistance under cyclic loading
• Rated torque of 1,134 inch-pounds for L100 series coupling applications
• 3.5 inches overall length and 2.54 inches outside diameter match L100 series hub geometry
• Spider-style insert design allows hub removal without disturbing connected shafts
• One spider plus two hubs (sold separately) completes the coupling assembly

Compatibility

Designed for use with LOVEJOY L100 series jaw coupling hubs. Two L100 hubs must be ordered separately to complete the coupling assembly. Verify coupling size code L100 on existing hubs before ordering.

Installation Notes

Installation is typically performed by millwrights or mechanical maintenance technicians following applicable machinery safety lockout and tagout procedures. De-energize and lock out the drive before disassembling or assembling any coupling components. Inspect hub bores and spider lobes for wear before reinstalling. Do not exceed the rated torque capacity of the coupling series during operation.
