We supply flexible sleeve for S-Flex coupling in three patterns: one-piece strong, one-piece split, and two-piece with retaining ring
The one-piece split design gives answers for applications with distinctive specifications where smaller shaft separations inhibit the installation of the one-piece reliable sleeve
Pre-molded teeth along the diameter from the sleeve engage with teeth of your coupling flanges
No clamps or screws are required to connect the flanges together with the flexible sleeve which securely lock with each other below torque for smooth transmission of power
Torque is transmitted through shear loading on the sleeve
All three sleeve products are extremely elastic which permits the S-Flex coupling to safeguard linked products from harmful shock loading, vibration, and shaft misalignment
JE, JN, JES, JNS Sleeve Types
These sleeves function a one-piece style and design molded in EPDM & Neoprene rubber. In the case of JES & JNS Styles, the one-piece design is split to provide for ease of installation and removal.
E, N Sleeve Types
These sleeves characteristic a two-piece style and design with retaining ring. The E Type is molded in EPDM rubber and the N Type is molded in Neoprene. The two-piece style is ideal 
for applications the place there is difficulty in separating the shafts of the driver and driven.
H, HS Sleeve Styles
These sleeves attribute both a one-piece strong (H) and two-piece split
(HS) design and style and are molded of Hytrel. The sleeves in Hytrel material are designed to transmit energy for high torque applications. Because on the layout and the properties in 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.
Sleeve Supplies
EPDM ?§C Unless otherwise specified, S-Flex couplings are supplied with EPDM flexible sleeves. EPDM has good resistance to commonly used chemicals and is generally not affected by dirt or moisture. Color is black.
NEOPRENE ?§C Neoprene presents very good performance characteristics for most applications and offers a very good resistance to chemical and oil conditions. Color is black with a green dot.
HYTREL ?§C 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.
