Bellows Flexible Shaft Couplings

Bellows Flexible Shaft Couplings

Featuring a flexible accordion-like section at the center of the coupling, these bellows flexible shaft couplings are a good choice for connecting shafts in applications where there is angular misalignment (shafts are set at an angle to each other), parallel misalignment (shafts are misaligned but parallel), or axial misalignment (shafts are pulled apart or pushed together) between the shafts.

These couplings allow minimal backlash (or play) between the shafts, and the bellows design helps absorb some vibration while providing good rigidity in moderate- to high-torque applications. Suitable for applications with high speeds, bellows flexible shaft couplings are often used in equipment such as encoders, resolvers, servomotors, robots, instruments, and machine tools. They do not require lubrication.

Clamp-On Mount

Set screws are not required to hold these couplings in place, making them less likely to damage the shaft than set-screw mount couplings. The clamp-on design evenly distributes the gripping force around the shaft for a more secure hold than set-screw mount couplings and makes it easier to fine-tune the coupling's position on the shaft.

Set-Screw Mount

Attach the hubs of these couplings to shafts using the included set screws. Once the coupling is in place, the set screw is tightened until it bites into the shaft material. For best results, the set screw should be made from a material that is harder than the shaft material.
