The Timken Company - E & N Type Elastomer Sleeves

Batch CAD Cart (0) ▾

Lovejoy offers flexible sleevse for S-Flex Endurance couplings in three designs: one-piece solid, one-piece split, and two-piece with retaining ring
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.
