Lovejoy 68514436405 Epdm Flexible Sleeve 7/8-2-3/8 in Bore

Product Description

The LOVEJOY 68514436405 is a flexible one-piece solid sleeve coupling designed to connect rotating shafts while absorbing vibration and accommodating minor misalignment. Constructed from Ethylene Propylene Diene Monomer (EPDM), this sleeve insert is part of the LOVEJOY JE Series and handles bore diameters from 0.875 inches up to 2.375 inches with a 6-inch outside diameter and a 3-inch overall length. It is rated to 1800 inch-pounds of torque, making it suitable for demanding drive applications. Licensed mechanics, millwrights, and industrial maintenance technicians are the typical installers.

This EPDM sleeve coupling is used in industrial power transmission applications where flexible shaft connections are required. The JE Series sleeve design fits between two flanged jaw hubs, cushioning shock loads and dampening torsional vibration in pumps, compressors, fans, conveyors, and similar rotating equipment. It is appropriate for both light commercial and industrial service environments where EPDM material properties — including resistance to heat, ozone, and weathering — are a benefit.

Key Features

• One-piece solid sleeve design eliminates the need for multiple insert segments during installation
• EPDM construction provides resistance to heat, ozone, and environmental weathering
• Accommodates bore range from 7/8 inch to 2-3/8 inches within a single sleeve size
• Rated torque capacity of 1800 inch-pounds for demanding drive system requirements
• JE Series sizing code 9 with 6-inch outside diameter for standardized hub compatibility
• Lightweight at 1.46 pounds, reducing added rotational mass in the drivetrain

Compatibility

Designed as an OEM-style replacement or standard service sleeve for LOVEJOY JE Series jaw coupling hubs accepting a size 9 sleeve insert with bore diameters between 7/8 inch and 2-3/8 inches.

Installation Notes

Installation is typically performed by qualified millwrights or industrial maintenance technicians. Always de-energize and lock out the drive motor and associated equipment before removing or installing any coupling component. Inspect mating jaw hubs for wear, cracking, or deformation before fitting the new sleeve. Verify shaft alignment is within the coupling manufacturer tolerances prior to returning the drive to service.
