Lovejoy 68514435570 7JE S-Flex J Type coupling sleeve is an EPDM elastomer component for press-fit J Type hubs. This size 7 sleeve provides torsional flexibility and damping, accommodating angular and parallel misalignment without lubrication. It operates within a temperature range of -40°F to 250°F and is ozone and weather resistant. The sleeve is designed to wrap around the lug flanges of two mating hubs to complete a flexible coupling assembly.

• The one-piece split design provides solutions for applications with unique requirements where small shaft separations inhibit the installation of a one-piece solid sleeve
• Pre-molded teeth along the diameter of the sleeve engage with teeth of the coupling flanges
• No clamps or screws are needed to connect the flanges with the flexible sleeve which securely lock together under torque for smooth transmission of power
• Torque is transmitted through shear loading of the sleeve
• All three sleeve materials are highly elastic which permits the S-Flex coupling to protect connected equipment from harmful shock loading, vibration, and shaft misalignment

JE, JN, JES, JNS Sleeve Types

These sleeves feature a one-piece design molded in EPDM & Neoprene rubber. In the case of JES & JNS Types, the one-piece design is split to provide for ease of installation and removal.
