The simple design of the S-Flex Endurance® coupling ensures ease of assembly and reliable performance. The standard S-Flex Endurance coupling is comprised of three parts: two flanges with internal teeth engaging an elastomeric flexible sleeve with external teeth.
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

The J Type flanges in sizes 3J and 4J are made from die cast of high strength zinc
alloy (tensile strength of 41,000 psi) and are furnished bore-to-size.
Size 5J is provided in either zinc alloy or cast iron depending on the bore size.
Size 6J is made from cast iron.
J flanges are compatible with EPDM or Neoprene sleeves.
Each flange has a keyway and two set screws (one set screw over the key and
one at 90° to the keyway).
The J Type coupling consists of two flanges and one sleeve.

Model TF flanges are made from the same high-strength cast iron as the S flanges, but are designed to
accommodate the international standard Taper Lock bushing for easy installation and removal
TF Type flanges allow for mounting the bushing on the front (hub) side of the flange
TF flanges are available in sizes 6 through 16 and can be used with JE, JN, JES, JNS, E, N, H, and HS sleeve types.
TR flanges are similar to the TF style, but allow for the Taper Lock Bushing to be mounted and removed from
the reverse or serration side of the flange
The limited torque ratings of the Taper Lock Bushings allow TR flanges to only be used with EPDM or Neoprene sleeves
Different bushing sizes are used, so they have different maximum bores than the TF flanges
