The Lovejoy JE type sleeve is a standard EPDM one-piece elastomer element for S-Flex (endurance) couplings, providing flexible torque transmission with vibration damping and misalignment tolerance.

Key Features:

• Molded of EPDM rubber, offering flexibility, vibration damping, and shock absorption.
• Pre-molded external teeth engage with the matching teeth on the coupling flanges so torque is transmitted by shear through the elastomer.
• No clamps or screws are required — the sleeve locks securely between the flanges under torque.
• Typical features include good resistance to common chemicals, moisture, and temperature ranges (approx. –30 °F to 375 °F / –34 °C to 135 °C) and the ability to accommodate misalignment while protecting equipment from vibration and shock loads.

The Lovejoy E Sleeve is a Two-piece sleeve EPDM Rubber with a retaining ring used in Lovejoy S-Flex (Endurance) couplings.

Key Features:

• Easy installation — Two pieces make it ideal when shaft ends are already in place or hard to separate.
• Good vibration damping and shock absorption (typical of EPDM).
• Suitable for larger couplings.
