Torque Limiter
Slips at a set torque to protect the machine from jams and overloads, then drives again once the overload clears.
- Set the slip torque a little above the highest working torque.
- Friction types slip smoothly; ball-detent types disengage sharply and repeatably.
- Carries a sprocket, a pulley or a coupling half.

| Type | Misalignment | Backlash | Shock damping | Torque | Best for |
|---|---|---|---|---|---|
| Jaw Coupling | Low, about 1° | Low | Good | 3–1,100 Nm | Motors to pumps, fans and gearboxes; fail-safe |
| Pin Bush Coupling | Low, about 0.5° | Low | Good | 50–50,000 Nm | Large motors in heavy industry; bushes change easily |
| Tyre Coupling | High, up to 4° | Some | Very good | 24–6,300 Nm | Shock loads and shafts that are hard to align |
| Gear Coupling | Medium, about 1.5° | Some | None | 500–100,000 Nm | Very high torque in a small size; needs grease |
| Resilient Coupling | Medium | Low | Very good | 100–50,000 Nm | Diesel engines and drives with torsional vibration |
| Disc Coupling | Low, about 1° | Zero | None | 50–10,000 Nm | High speed and precision, no lubrication |
| Servo Coupling | Low to medium | Zero | None | 0.5–500 Nm | Servo motors, encoders and ball screws |
| Chain Coupling | Low, about 1° | Some | None | 50–20,000 Nm | Simple, compact drives; easy to disconnect |
| Torque LimiterYou are here | Depends on the drive it carries | Low | None | 2–5,000 Nm slip setting | Protecting machines from jams and overloads |
| Nylon Gear Coupling | Medium, about 1° | Low | Some | 10–2,000 Nm | Pumps and general drives; no lubrication, quiet |
| Locking Assembly | None, it is a rigid shaft-hub joint | Zero | None | 20–100,000 Nm | Fixing pulleys, sprockets and hubs to a shaft without a keyway |
