Taper Bush
A split, tapered bush that locks a pulley, sprocket or coupling hub to a shaft. Tightening the screws pulls the bush into the hub and grips the shaft.
- Comes in finished bores with a keyway, so the hub needs no machining.
- The bush size (e.g. 1210, 2517) must match the size of the taper bore in the hub.
- Removed easily: move a screw to the jacking hole and tighten it.

| 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 | Low to medium, about 0.3° | Low | Good | 50–100,000 Nm | Heavy drives with shock loads: conveyors, crushers, mills |
| 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 Limiter | Depends on the drive it carries | Low | None | 2–5,000 Nm slip setting | Protecting machines from jams and overloads |
| Torque Limiter Coupling | Low to medium, from its coupling | Low | Depends on the coupling | 2–5,000 Nm slip setting | Joining two shafts and protecting them from 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 |
