Lovejoy 68514435600 Flexible Two Piece Sleeve Epdm

Product Description

The LOVEJOY 68514435600 is a flexible two-piece sleeve insert designed for use in jaw-type flexible couplings. Manufactured from Ethylene Propylene Diene Monomer (EPDM), this sleeve element fits between the jaws of mating coupling hubs to transmit torque while absorbing shock, vibration, and minor misalignment. It carries a rated torque capacity of 450 inch-pounds and fits a minimum bore diameter of 0.625 inches. The outside diameter measures 3.75 inches with an overall length of 1.88 inches. This part belongs to the LOVEJOY JE Series and is installed by millwrights, industrial maintenance technicians, and mechanical contractors working on rotating equipment.

This sleeve is suited for pump, compressor, conveyor, and general industrial drive applications where a resilient coupling element is required. EPDM construction makes it appropriate for environments with exposure to water, steam, or mild chemical contact. The two-piece design allows the sleeve to be removed and replaced without disturbing the coupling hubs or disconnecting the shaft alignment, which reduces downtime during routine maintenance. It is used in both light commercial and industrial settings wherever a JE Series or compatible jaw coupling of size code 6 is installed.

Key Features

• EPDM material provides resistance to water, steam, and mild chemical exposure
• Two-piece sleeve design enables replacement without moving hubs or realigning shafts
• Rated torque capacity of 450 inch-pounds (66.09 Newton-meters)
• Outside diameter of 3.75 inches fits JE Series size code 6 jaw couplings
• Compact 1.88-inch overall length for tight drive arrangements
• Sleeve insert style absorbs shock and vibration between drive and driven equipment

Compatibility

Designed as a replacement sleeve insert for LOVEJOY JE Series jaw-type flexible couplings at coupling size code 6 with a minimum bore diameter of 0.625 inches.

Installation Notes

Installation and replacement should be performed by a qualified millwright or mechanical technician. De-energize and lock out all rotating equipment before servicing any coupling component in accordance with applicable OSHA lockout/tagout procedures. The two-piece sleeve can be installed by positioning each half between the mating coupling hubs without axial movement of the shafts. Inspect hub jaws for wear or damage before installing a new sleeve element.
