Metal Beam Flexible Shaft Couplings

Metal Beam Flexible Shaft Couplings

Made from a single cylindrical piece of material, beam flexible shaft couplings have multiple spiral cuts along their length that allow them to bend to accommodate 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) when the coupling is connected between two shafts.

Beam couplings allow zero backlash (or play) and are often used for applications where the drive system will be stopped and started frequently, such as servo motion control. 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.
