Elastomer Designs

We supply flexible sleeve for S-Flex coupling in 3 designs: one-piece sound, one-piece split, and two-piece with retaining ring
The one-piece split design presents solutions for applications with distinctive needs where modest shaft separations inhibit the installation of the one-piece sound sleeve
Pre-molded teeth along the diameter in the sleeve engage with teeth from the coupling flanges
No clamps or screws are essential to connect the flanges using the flexible sleeve which securely lock with each other beneath torque for smooth transmission of energy
Torque is transmitted by means of shear loading of the sleeve
All 3 sleeve components are remarkably elastic which permits the S-Flex coupling to protect connected products from dangerous shock loading, vibration, and shaft misalignment
JE, JN, JES, JNS Sleeve Types
These sleeves feature a one-piece layout molded in EPDM & Neoprene rubber. In the case of JES & JNS Varieties, the one-piece style is split to provide for ease of installation and removal.
E, N Sleeve Sorts
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 wherever there is difficulty in separating the shafts of your driver and driven.
H, HS Sleeve Styles
These sleeves feature both a one-piece solid (H) and two-piece split
(HS) design and style and are molded of Hytrel. The sleeves in Hytrel material are designed to transmit electrical power for high torque applications. Because of your design and the properties from 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 Materials
EPDM ?§C Unless otherwise specified, S-Flex couplings are supplied with EPDM versatile sleeves. EPDM has good resistance to commonly used chemicals and is generally not affected by dirt or moisture. Color is black.
NEOPRENE ?§C Neoprene provides 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.
