• Unless otherwise specified, S-Flex couplings are supplied with EPDM Flexible sleeves
• EPDM has good resistance to commonly used chemicals and is generally not affected by dirt or moisture
• Lovejoy offers Flexible sleeve for S-Flex coupling in (3) designs: 1-piece solid, 1-piece split and 2-piece with retaining ring
• The 1-piece split design provides solutions for applications with unique requirements where small shaft separations inhibit the installation of a 1-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 3-sleeve materials are highly elastic which permits the S-flex coupling to protect connected equipment from harmful shock loading, vibration and shaft misalignment
