We provide flexible sleeve for S-Flex coupling in 3 styles: one-piece strong, one-piece split, and two-piece with retaining ring
The one-piece split style and design gives options for applications with exceptional prerequisites exactly where modest shaft separations inhibit the installation of a one-piece sound sleeve
Pre-molded teeth along the diameter of the sleeve engage with teeth of the coupling flanges
No clamps or screws are essential to connect the flanges with the versatile sleeve which securely lock together below torque for smooth transmission of electrical power
Torque is transmitted via shear loading on the sleeve
All three sleeve elements are remarkably elastic which permits the S-Flex coupling to protect linked equipment from unsafe shock loading, vibration, and shaft misalignment
JE, JN, JES, JNS Sleeve Forms
These sleeves feature a one-piece style molded in EPDM & Neoprene rubber. In the case of JES & JNS Forms, the one-piece design is split to provide for ease of set up and removal.
E, N Sleeve Types
These sleeves function 
a two-piece style with retaining ring. The E Type is molded in EPDM rubber and the N Type is molded in Neoprene. The two-piece style and design is ideal for applications wherever there is difficulty in separating the shafts on the driver and driven.
H, HS Sleeve Styles
These sleeves feature both a one-piece strong (H) and two-piece split
(HS) design and are molded of Hytrel. The sleeves in Hytrel material are designed to transmit energy for high torque applications. Because of your style and design and the properties with 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 Products
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 gives 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.
