✅ 4140 alloy steel for extreme shock loads — C45 fails in this application.
✅ HRC 45-55 hardened teeth — resists rock/mineral abrasion.
✅ Split hub / QD for field replacement — minimises expensive downtime.
✅ Full EN 10204 3.1 material traceability — meets audit requirements.
Locations: Track drive, bucket chain, slewing mechanism, auxiliary conveyor. Function: Convert motor torque into precise material feed and processing motion.
OEM: Caterpillar*, Komatsu*, Volvo CE*, Hitachi*, Liebherr* systems. *Compatibility reference only.
Select: ❶ Match chain pitch ❷ Shaft bore → hub type ❸ Tooth count for speed ratio ❹ Material grade for environment ❺ Surface treatment for corrosion protection.
Install: LOTO → release chain → remove old sprocket → mount new (TL = rapid change) → align → tension 2-3% → lubricate → test.
Issues: Chain riding teeth = worn sprocket (replace both). Vibration = misalignment/bore runout. Excessive noise = dry chain. Chain skipping = elongated chain + worn teeth (replace both).
Pilbara, WA: “Precision sprockets matched OEM specs. Running well.” ★★★★★
Sydney, NSW: “Split hub saved hours during shutdown. Material certs provided.” ★★★★★
Brisbane, QLD: “Consistent quality across multiple orders. Hardened teeth lasting well.” ★★★★☆
Adelaide, SA: “QD bushed on large shaft. Rapid installation, running true.” ★★★★★
Melbourne, VIC: “Professional documentation, competitive pricing, reliable supply.” ★★★★★
