Lovejoy 68514436704 Split Sleeve Epdm 5/8 to 1-5/8 Inch Bore

Product Description

The LOVEJOY 68514436704 is a flexible one-piece split sleeve coupling insert made from Ethylene Propylene Diene Monomer (EPDM). It is designed to transmit torque between coupled shafts while absorbing vibration and accommodating minor misalignment. The sleeve fits bore diameters ranging from 5/8 inch to 1-5/8 inch and carries a rated torque of 725 inch-pounds. With an overall length of 2.19 inches and an outside diameter of 4.34 inches, this Series JE sleeve insert is the flexible element that lives between the two hubs of a jaw-type coupling assembly. Installation and replacement are handled by mechanics and millwrights in industrial, HVAC, and pump-drive applications.

This sleeve is suited for use in rotating equipment drives where cushioning and vibration damping are priorities. EPDM material provides good resistance to heat, ozone, and weathering, making it appropriate for both indoor mechanical rooms and exposed mechanical systems. The split one-piece design allows the sleeve to be replaced without disturbing the shaft alignment or removing the coupled hubs, which reduces downtime during routine maintenance. Typical applications include small pump drives, fan shaft couplings, and compressor drives found in commercial HVAC and light industrial settings.

Key Features

• One-piece split sleeve design allows replacement without hub removal or shaft realignment
• EPDM material offers resistance to heat, ozone, and environmental weathering
• Accommodates bore diameters from 5/8 inch to 1-5/8 inch in a single sleeve
• Rated torque of 725 inch-pounds for reliable power transmission
• Series JE sleeve insert style for jaw-type coupling assemblies
• Compact form factor at 2.19 inches OAL and 4.34 inches OD

Compatibility

Designed as a Series JE sleeve insert for jaw-type flexible coupling assemblies accepting bore diameters from 5/8 inch to 1-5/8 inch. Consult the coupling hub specifications to confirm Series JE fitment before installation.

Installation Notes

Coupling sleeve replacement is typically performed by a qualified mechanic or millwright. De-energize and lock out the drive motor before servicing any rotating equipment in accordance with OSHA lockout/tagout procedures. The split one-piece sleeve can be installed by spreading it open and seating it between the engaged hubs without shaft disassembly. Inspect both hubs for wear or cracking before installing the new sleeve, and verify shaft alignment is within the coupling manufacturer's tolerance.
