Overview
The Lovejoy 685144 35451 10JES EPDM sleeve is a split-design elastomer coupling element for Lovejoy S-Flex flexible coupling assemblies. Made of ethylene propylene diene monomer (EPDM) synthetic rubber, it is designed for transferring and absorbing shock load. The single split piece enables easier installation when coupled shafts must be separated, and its teeth help distribute torsional load across the elastomer and flanges, reducing wear and extending service life.
Key Features
- EPDM synthetic rubber construction for shock load absorption and vibration damping
