Lovejoy 68514436433 Two Piece Sleeve 1-1/4 in Epdm 4 in

Product Description

The LOVEJOY 68514436433 is a flexible two-piece sleeve coupling insert made from Ethylene Propylene Diene Monomer (EPDM), designed to transmit torque between shaft ends while absorbing vibration and minor misalignment. Rated at 4,530 in/lb (665.37 N/m) of torque capacity, this sleeve insert fits a minimum bore diameter of 1-1/4 inches and has an overall length of 4 inches with an outside diameter of 8.19 inches. It is used in mechanical power transmission applications and is installed by millwrights, maintenance technicians, and industrial service professionals.

This sleeve insert is suited for use in Series 11 jaw-style flexible coupling assemblies. The two-piece construction allows installation and removal without moving the connected shafts, making it practical in tight machine installations. EPDM material provides good resistance to heat, ozone, and weathering, making this sleeve appropriate for both indoor mechanical systems and outdoor or exposed equipment. This part ships as a single unit.

Installation Notes

Installation is typically performed by a qualified millwright or maintenance technician. De-energize and lock out all power to the connected equipment before servicing the coupling. The two-piece sleeve design eliminates the need to move hubs or connected shafts during replacement. Verify hub condition and alignment specifications before installing the new sleeve to avoid accelerated wear.
