Use your air system to remotely make changes to the torque setting or cut off torque completely, even during operation. Adjust the torque setting by adjusting the air pressure—the higher the pressure, the higher the set torque. When these torque limiters exceed their set torque, they’ll slip but still transmit the set torque. They use friction to prevent torque overload, control tension, and brake. They’re often used in automated systems. For instance, they can be used in a machine that tightens a bottle cap to a certain torque without overtightening it and breaking the bottle. Because they rely on friction, exposing them to moisture, oil, or lubricants can affect their performance.

Fasten them to your shaft by tightening the set screws, which bite into the shaft to hold it.

Shaft-to-shaft torque limiters also act as a shaft coupling, allowing you to regulate torque transmission between two shafts.

Through-shaft torque limiters regulate torque transmission between an input shaft and a mounted component, such as a pulley, sprocket, or gear.
