Air-Powered Torque-Limiting Shaft-to-Gear Couplings
For Round Shafts
For Keyed Shafts
Often used in automated systems, these couplings are both air actuated and remotely adjustable, so you can adjust the torque setting even 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.

Magnetic Torque-Limiting Shaft-to-Gear Couplings
Also known as hysteresis clutches, these couplings use magnetic force to brake, control tension, and prevent torque overload. They have few moving parts, so they last longer than mechanical couplings. Twist the adjustment ring to set the torque within the range listed, then lock the ring in place with the included set screw.

Electromagnetic Tensioning, Holding, and Stopping Shaft-to-Gear Couplings
Also known as electric hysteresis brakes, these couplings use magnetic force to create drag to slow or stop the motion of your drive system. Use them with a current-limiting transformer to adjust the electrical current, which controls the amount of torque applied.

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.
