We supply versatile sleeve for S-Flex coupling in 3 types: one-piece strong, one-piece split, and two-piece with retaining ring
The one-piece split style offers solutions for applications with distinctive requirements wherever small shaft separations inhibit the set up of a one-piece reliable sleeve
Pre-molded teeth along the diameter of the sleeve engage with teeth from the coupling flanges
No clamps or screws are required to connect the flanges with the versatile sleeve which securely lock together beneath torque for smooth transmission of energy
Torque is transmitted by means of shear loading of the sleeve
All 3 sleeve components are highly elastic which permits the S-Flex coupling to guard linked gear from dangerous shock loading, vibration, and shaft misalignment
JE, JN, JES, JNS Sleeve Types
These sleeves attribute a one-piece style molded in EPDM & Neoprene rubber. In the case of JES & JNS Forms, the one-piece style and design is split to provide for ease of installation and removal.
E, N Sleeve Styles
These sleeves feature 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 design is ideal for applications in which there is difficulty in separating the shafts from the driver and driven.
H, HS Sleeve Kinds
These sleeves feature 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 electrical power for high torque applications. Because from the layout and the properties of your 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 Elements
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 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.
