Torque-Limiting Flexible Shaft Couplings

Our torque-limiting flexible shaft couplings are designed to protect your machine's shafts, motors, and gearboxes from damage caused by torque overload due to machine jams or emergency stops. When the set torque is exceeded, these couplings disengage and then automatically re-engage once the torque is back within range. Our couplings are capable of handling more than five times as much torque as other flexible shaft couplings, ensuring greater protection for your machine. Connect our couplings to your shafts easily with the included set screws that bite into the shaft or shaft and key for a secure hold.
We offer single-spring couplings that allow you to make finer torque adjustments than double-spring couplings, although they can only withstand half as much torque. Double-spring couplings, on the other hand, can handle twice as much torque as single-spring couplings but may not be ideal for making precise adjustments at low torques. Our couplings for keyed shafts have keyways that are cut to standard ANSI dimensions, ensuring a snug fit on ANSI keyed shafts to eliminate slipping during starts and stops. Order now and protect your machine's components from torque overload damage.
