About Shaft Couplings

High-Misalignment Vibration-Damping Precision Flexible Shaft Couplings

Also called double-loop couplings, these have a flexible center that reduces vibration and compensates for high parallel and angular shaft misalignment. They allow zero backlash (no play) and will run smoothly and quietly. Fasten to your shaft by tightening the set screws, which bite into the shaft to hold it.
Stainless steel couplings offer excellent corrosion resistance.

Connection-Severing Flexible Shaft Couplings

To protect power-transmission components from damage, these couplings will shear or tear in overtorque conditions (approximately 10-20 times the maximum rated torque) to sever connections between shafts. They have a flexible center that not only compensates for misalignment, but also dampens vibration and shock loads. Couplings have no metal-on-metal contact, reducing noise and eliminating the need for lubrication. Fasten to your shaft by tightening the set screws, which bite into the shaft to hold it.
