Lovejoy 68514436707 Split Sleeve Coupling 3/4 in Epdm

Product Description

The LOVEJOY 68514436707 is a flexible one-piece split sleeve coupling designed for shaft-to-shaft power transmission in light to medium-duty mechanical systems. Constructed from Ethylene Propylene Diene Monomer (EPDM), the sleeve insert provides elasticity and vibration dampening while accommodating minor misalignment between connected shafts. The coupling 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 for a maximum torque of 1,135 inch-pounds (166.66 N/m), making it suitable for a range of industrial and mechanical drive applications. The one-piece split sleeve design simplifies installation and removal without the need to disassemble the entire drivetrain.

This coupling is intended for use in mechanical power transmission assemblies where flexible shaft coupling is required. The Series JE split sleeve design is commonly installed in conveyor systems, pump drives, compressor connections, and general industrial machinery. The EPDM sleeve insert material offers good resistance to heat, ozone, and weathering, making it appropriate for both indoor and outdoor mechanical installations. Maintenance technicians and mechanical contractors typically specify this style of coupling in applications requiring periodic sleeve replacement without full shaft disassembly.

Key Features

• One-piece split sleeve design allows sleeve replacement without full shaft teardown
• EPDM material provides vibration dampening and accommodates minor shaft misalignment
• Rated for 1,135 inch-pounds (166.66 N/m) of torque
• 3/4 inch minimum bore diameter fits common shaft sizes
• 5.06 inch outside diameter with 2.5 inch overall length for compact installation envelope
• Series JE sleeve insert style for straightforward fitment in compatible jaw coupling hubs

Compatibility

Designed as an OEM-style replacement sleeve insert for compatible LOVEJOY Series JE jaw coupling hubs sized for a 3/4 inch bore. Verify hub series and coupling size code 8 before ordering.

Installation Notes

Installation is typically performed by mechanical technicians or millwrights. Disengage and lock out all power to the connected drive system before removing the existing sleeve or handling the coupling assembly. The split sleeve design allows the insert to be removed and replaced laterally without disturbing shaft alignment or removing the hubs. Confirm shaft alignment is within acceptable tolerances before operating the assembly, as excessive misalignment will accelerate sleeve wear.
