Rock crusher sprockets drive the chain mechanisms in jaw crushers, cone crushers, impact crushers, and feeder systems used in quarrying, mining, and construction aggregate production across Australia. These sprockets endure the most extreme shock loads, abrasive dust, and vibration of any industrial application. We supply crusher sprockets in 4140 alloy steel with induction-hardened teeth HRC 45-55, QD/split hubs, and full EN 10204 Type 3.1 traceability.

Where: Crusher feeder chain drive, discharge conveyor head, vibrating grizzly mechanism, crusher toggle drive. Functie: Transmit high-torque, shock-loaded power from motor/gearbox to crusher feed and discharge mechanisms.
✅ 4140 alloy steel survives 3x shock overloads — C45 cracks under crusher impact loading.
✅ HRC 45-55 resists abrasive rock dust — unhardened teeth erode within weeks.
✅ Split hub for field replacement — crusher downtime costs AUD 5,000-20,000/hour.
OEM: Metso*, Sandvik*, FLSmidth*, Terex*, Kleemann* crushers. *Compatibility ref only.
