Lovejoy catalog number 68514436419 is an 8E series elastomeric sleeve for S-Flex flange couplings. This EPDM rubber sleeve provides torsional flexibility and damping, accommodating angular, parallel, and axial misalignment without lubrication. It is designed to wrap around the lug flanges of two 8E series hubs to form a complete coupling assembly, suitable for pumps, fans, and compressors in general industrial applications.

• 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
• All three sleeve materials are highly elastic which permits the S-Flex coupling to protect connected equipment from harmful shock loading, vibration, and shaft misalignment

E, N Sleeve Types

• These sleeves feature a two-piece 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 where there is difficulty in separating the shafts of the driver and driven.

Features

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.

Notes

• Two piece sleeves are ideal for applications where small shaft separations inhibit the installation of a one piece sleeve.
