Use friction to prevent torque overload, control tension, and brake. These torque limiters slip when there’s too much torque while still transmitting the set torque. For example, they could be used in a machine that tightens a bottle cap to a certain torque without overtightening and breaking the bottle. Because they rely on friction, exposing them to moisture, oil, or lubricants can affect their performance. They have an adjustment ring, so you can set the torque limit by hand without removing them from your shaft. 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.

With rugged roller chains, these torque limiters handle more torque than other torque limiters. They have a disc that creates friction to prevent torque overload, control tension, and brake. If there’s too much torque, they’ll slip and only transmit the set torque. For example, they could be used in a machine that tightens a bottle cap to a certain torque without overtightening and breaking the bottle. Because they rely on friction, exposing them to moisture, oil, or lubricants can affect their performance. You can adjust the torque by rotating the hex nut on the hub.

They act as a flexible shaft coupling, so they reduce vibration and protect components from wear by compensating for angular and parallel misalignment. Fasten them to your shafts by tightening the set screws, which bite into each shaft to hold it.

Single-spring torque limiters let you make finer torque adjustments than double-spring torque limiters but can only withstand half as much torque.

Double-spring torque limiters handle twice as much torque as single-spring torque limiters but are not the best for making precise adjustments at low torques.

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.
