Request Information
  • Lovejoy offers flexible sleeves for S-Flex Endurance couplings in three designs: one-piece solid, one-piece split, and two-piece with retaining ring
  • 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.
