Torque-Limiting Shaft Couplings


Adjust your system's torque limit by hand. In the event of excess torque, these couplings slip to protect motors and drivetrains, and then resume driving once the load has been reduced. You can adjust the torque level without removing them from your shaft.

Air-Powered Torque-Limiting Shaft Couplings


Often used in automated systems, these couplings are air actuated so you can adjust the torque during operation. In the event of excess torque, they slip to protect motors and drivetrains, and then resume driving once the load has been reduced. You can adjust the torque level without removing them from your shaft.

Torque-Limiting Flexible Shaft Couplings with Alarm

If they exceed maximum torque, these couplings disengage, sound an alarm, and then automatically re-engage once the overtorque condition is eliminated. Torque can be adjusted ±10% of the factory setting. No lubrication is required. Fasten to your shaft by tightening the set screws, which bite into the shaft to hold it.

Torque-Limiting Flexible Shaft Couplings



Protect shafts, motors, and gear boxes from damage that’s caused by torque overload from machine jams and emergency stops. If your set torque is exceeded, these couplings will disengage and then automatically re-engage once the torque is back within range. They handle more than five times as much torque as our other torque-limiting flexible shaft couplings. Connect them to your shafts with the included set screws, which bite into the shaft or shaft and key for a secure hold.
Single-spring couplings let you make finer torque adjustments than the double-spring couplings, but can only withstand half as much torque.
Double-spring couplings handle twice as much torque as the single-spring couplings, but are not the best for making precise adjustments at low torques.
Couplings for keyed shafts have keyways that are cut to standard ANSI dimensions, so they’ll fit snugly on ANSI keyed shafts to eliminate slipping during starts and stops.

Torque Limiters for Chain and Belt Drives
Prevent damage from overloading. When overloaded, these limiters cause your sprocket or pulley to slip. Once the overload is removed, the limiters automatically reset. Set the torque within the range listed. Friction discs are between the hub and pressure plate.
Double-spring limiters have a second spring for handling nearly twice the torque of single-spring limiters.
Optional sprockets are designed specifically to fit their corresponding limiters. These hubless sprockets are not interchangeable.
