  • Lovejoy offers flexible sleevse 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
E, N Sleeve Types
  • These sleeves feature a two-piece design with retaining ring. The E Type is molded in EPDM rubber and the N Type is molded in Neoprene. The two- piece design is ideal for applications where there is difficulty in separating the shafts of the driver and driven.
