    High-Torque Friction Torque Limiters

    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—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—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.
