Lovejoy 68514410411 Flexible Spider Coupling Insert Urethane

Product Description

The LOVEJOY 68514410411 is a urethane flexible spider insert designed for use in jaw-type flexible shaft couplings. This component fits between two mating hubs to transmit torque while absorbing shock, dampening vibration, and accommodating minor shaft misalignment. It belongs to the L070 coupling series and carries a maximum bore diameter of 0.75 inches and an outside diameter of 1.36 inches. With a torque rating of 65 in/lb, this spider is sized for light-duty power transmission applications. The part weighs 0.02 pounds and measures 2 inches in overall length. Mechanical contractors, industrial maintenance technicians, and HVAC equipment installers work with this type of component when servicing direct-drive assemblies.

This spider insert is used in residential and light commercial mechanical systems where jaw couplings connect motor shafts to driven equipment such as pumps, blowers, and compressors. It is sold as a single spider element. Two hubs must be ordered separately to assemble a complete coupling. The L070 series designation identifies the coupling size and hub compatibility. Proper hub selection requires matching the same series code to ensure correct fit and torque transfer.

Key Features

• Urethane construction absorbs shock loads and dampens torsional vibration
• Maximum bore diameter of 0.75 inches suits common light-duty shaft sizes
• Outside diameter of 1.36 inches fits L070 series jaw coupling hubs
• Torque rating of 65 in/lb for light-duty power transmission
• Overall length of 2 inches for compact drive train installations
• Single-piece spider element sold individually; two hubs required for complete assembly

Compatibility

Designed for use with L070 series jaw coupling hubs. Two L070 hubs must be ordered separately to complete the coupling assembly. Confirm hub bore diameter and series code before ordering.

Installation Notes

De-energize and lock out all power to the driven equipment before servicing any coupling component. Inspect both mating hubs for wear, scoring, or jaw deformation before installing a replacement spider. Ensure shaft and hub bores are clean and free of burrs prior to assembly. Follow applicable ANSI and OSHA lockout/tagout procedures throughout the service procedure.
