Lovejoy catalog number 68514436848 is a 7H neoprene sleeve for heavy-duty cushion (C/H type) couplings. This elastomeric component is designed for high-torque and shock-load applications, offering oil resistance and operating within a temperature range of -40°F to 180°F. It is compatible with C175 through H285 series cushion coupling hubs, providing torsional flexibility and vibration dampening in demanding industrial power transmission systems.

Type
1-Piece Solid
- 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
H, HS Sleeve Types
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.

Features
Hytrel is a polyester elastomer designed for high torque and high temperature applications and offers excellent resistance to chemical and oil conditions. Color is orange.
Notes
- 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.
