Lovejoy 68514436429 Flexible Two Piece Sleeve Epdm

Product Description

The LOVEJOY 68514436429 is a flexible two-piece sleeve coupling insert made from Ethylene Propylene Diene Monomer (EPDM) rubber. It is designed to transmit torque between shaft ends while absorbing shock, vibration, and minor misalignment in mechanical drive systems. The sleeve fits a minimum bore diameter of 1.125 inches and measures 3.44 inches in overall length with an outside diameter of 7.06 inches. Rated at 2,875 in/lb (422 N/m) of torque capacity, this Series 10 sleeve insert is installed by millwrights, industrial mechanics, and maintenance technicians working on coupled drive assemblies in HVAC, pump, and general industrial equipment.

This sleeve is suited for light to medium industrial applications where flexible coupling performance is required. The two-piece design allows the sleeve to be installed and removed without disturbing the hubs or disconnecting the coupled shafts, making it practical for maintenance-interval replacements. EPDM material provides resistance to heat, ozone, and weathering, making this sleeve appropriate for both indoor mechanical rooms and outdoor or semi-exposed installations. It is commonly used in pump drives, fan drives, and compressor couplings.

Key Features

• Two-piece sleeve design allows removal without shaft disassembly
• EPDM construction resists heat, ozone, and environmental weathering
• Rated torque capacity of 2,875 in/lb (422 N/m)
• Minimum bore diameter of 1.125 inches suits Series 10 coupling hubs

• Sleeve Insert style compatible with standard jaw-type flexible coupling assemblies

Compatibility

Designed as an OEM-style replacement sleeve for LOVEJOY Series 10 two-piece flexible jaw couplings with a minimum bore diameter of 1.125 inches.

Installation Notes

Installation and replacement should be performed by a qualified mechanical technician or millwright. De-energize and lock out all power to the drive system before servicing the coupling. The two-piece sleeve can be separated and fitted around the coupling element without removing the hubs from the shafts. Inspect hub spider seats for wear before installing a new sleeve, and confirm shaft alignment is within coupling tolerances before returning the drive to service.
