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
These sleeves feature both a one-piece solid (H) and two-piece split (HS) design and are molded of Hytrel. The sleeves in Hytrel material are designed to transmit power for high torque applications. Because of the design and the properties of the Hytrel molded sleeve, the H and HS sleeves should not be used as direct replacements for EPDM or Neoprene sleeves, and can only be used with S, TF, or SC flanges.
Operating Hytrel within a high service factor application is not recommended.
H and HS Type sleeves are designed for high torque applications, transmitting about 4 times as much power as an equivalent EPDM or Neoprene sleeve.
Hytrel sleeves can be used only with S or SC flanges and can not be used with J or B flanges.
Hytrel sleeves should not be used as direct replacements for EPDM or Neoprene applications.
