Lovejoy 68514436419 Flexible Two Piece Sleeve Epdm

Product Description

The LOVEJOY 68514436419 is a flexible two-piece sleeve coupling insert designed for shaft-to-shaft power transmission in mechanical drive systems. Made from Ethylene Propylene Diene Monomer (EPDM), it absorbs vibration, accommodates minor misalignment, and resists weathering and ozone degradation. The sleeve fits a 3/4 inch minimum bore diameter and measures 2.5 inches in overall length with a 5.06 inch outside diameter. It is rated at 1,135 inch-pounds of torque and belongs to the LOVEJOY Series JE sleeve coupling family. This component is typically installed by mechanical contractors, millwrights, and maintenance technicians in industrial and commercial drive applications.

This sleeve insert is used in Series JE jaw-type flexible couplings found in pump, compressor, conveyor, and general industrial drive setups. The EPDM material makes it suitable for outdoor and moderate-chemical-exposure environments where standard rubber compounds may degrade prematurely. It functions as the flexible element seated between the two coupling hubs, isolating vibration and shock loads between connected shafts. Sold as a single sleeve insert, it is intended for replacement or initial assembly of compatible Series JE coupling assemblies.

Key Features

• EPDM construction resists ozone, weathering, and moderate chemical exposure
• Rated torque of 1,135 inch-pounds (166.66 N/m) for reliable power transmission
• 3/4 inch minimum bore diameter fits standard Series JE coupling hubs
• 5.06 inch outside diameter and 2.5 inch overall length for compact drive installations
• Two-piece sleeve design allows removal and replacement without disturbing shaft alignment
• Series JE size code 8 designation for straightforward catalog cross-reference

Compatibility

Designed for use with LOVEJOY Series JE jaw-type flexible couplings, size code 8, requiring a sleeve insert with a 3/4 inch minimum bore diameter. Verify hub size and series designation before installation.

Installation Notes

Installation is typically performed by millwrights or mechanical maintenance technicians. Always de-energize and lock out the drive system before removing or installing the sleeve insert. The two-piece design allows the sleeve to be replaced without moving the hubs off the shafts, but confirm shaft alignment and hub seating before returning the drive to service. Follow the equipment manufacturer's coupling assembly guidelines and applicable ANSI/AGMA standards for coupling installation.
