Lovejoy 68514435368 Flexible Two Piece Sleeve Epdm

Product Description

The LOVEJOY 68514435368 is a flexible two-piece sleeve insert designed for use in jaw-style coupling assemblies. Manufactured from Ethylene Propylene Diene Monomer (EPDM), this sleeve fits between the two coupling hubs to transmit torque while absorbing shock, vibration, and minor misalignment. It is sized for a 1/2 inch minimum bore diameter, measures 1.56 inches in overall length, and has an outside diameter of 2.94 inches. Rated at 240 in/lb (35.26 Nm) of torque capacity, it belongs to the Series JE sleeve family. Installation is handled by millwrights, mechanical contractors, or maintenance technicians working on power transmission equipment.

This sleeve is used in industrial and commercial power transmission applications where jaw couplings connect rotating shafts on motors, pumps, compressors, and similar driven equipment. The two-piece design allows the sleeve to be replaced without moving the hubs apart, which reduces downtime during maintenance. EPDM material makes this sleeve suitable for environments with exposure to water, steam, and mild chemical conditions. It is sold individually as a single replacement element.

Key Features

• Two-piece sleeve insert design allows replacement without disturbing hub alignment
• EPDM construction provides resistance to water, steam, and mild chemical exposure
• Rated torque capacity of 240 in/lb (35.26 Nm)

• Series JE coupling size code 5 classification for straightforward cross-referencing
• Absorbs shock and vibration to protect connected equipment

Compatibility

Designed as a Series JE jaw coupling sleeve replacement for assemblies requiring a size code 5 EPDM insert with a 1/2 inch minimum bore diameter. Verify hub series and size code before ordering to confirm fitment.

Installation Notes

De-energize and lock out the drive motor before servicing any coupling assembly in accordance with applicable OSHA lockout/tagout procedures. The two-piece sleeve can typically be removed and inserted radially without axial hub movement, but confirm hub clearance before proceeding. Inspect hub spider seats for wear or damage before installing the new sleeve. Torque any hub fasteners to the equipment manufacturer's specifications found in the machine documentation.
