Lovejoy 68514435451 Split Sleeve 1-1/8 in Bore Epdm

Product Description

The LOVEJOY 68514435451 is a flexible one-piece split sleeve coupling designed for shaft-to-shaft power transmission in industrial and mechanical drive applications. Manufactured from Ethylene Propylene Diene Monomer (EPDM), it offers good resistance to heat, ozone, and environmental exposure. The sleeve fits a minimum bore diameter of 1.125 inches and measures 3.44 inches overall length with a 7.06 inch outside diameter. Rated at 2,875 inch-pounds (422 Newton-meters) of torque, this coupling is sized for Series 10 jaw-style coupling assemblies. It is installed by mechanical technicians and millwrights in pump, compressor, and motor drive trains.

This split sleeve is suited for use in light industrial and commercial mechanical systems where flexible coupling elements are required to transmit torque while accommodating minor shaft misalignment. The one-piece split sleeve design allows for replacement without disconnecting shafting, making it a practical maintenance item in pump rooms, mechanical equipment rooms, and process equipment installations. It is commonly serviced by millwrights, maintenance mechanics, and HVAC or plumbing technicians working on close-coupled equipment.

Key Features

• One-piece split sleeve design allows removal and installation without full shaft disassembly
• EPDM material provides resistance to heat, ozone, and moderate chemical exposure
• Rated at 2,875 inch-pounds of torque for reliable power transmission
• Series 10 coupling size code for straightforward cross-referencing
• 1.125 inch minimum bore diameter fits standard Series 10 jaw coupling hubs
• 7.06 inch outside diameter and 3.44 inch overall length for compact drive installations

Compatibility

Designed as an OEM-style replacement flexible element for Series 10 jaw-style coupling assemblies requiring a one-piece split sleeve insert with a 1.125 inch minimum bore diameter.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. De-energize and lock out the drive motor before servicing any coupling components. Verify that mating hub bores, keyways, and set screws are in good condition before fitting the new sleeve. Do not operate the coupling above its rated torque capacity.
