Coil handling sprockets drive the chain conveyors and turnstile mechanisms that transport steel, aluminium, and paper coils through slitting, levelling, and packaging lines. Heavy coil weights (up to 30 tonnes) demand duplex/triplex configurations with 4140 alloy steel.

✅ 4140 alloy steel for extreme shock loads — C45 fails in this application.
✅ HRC 40-50 hardened teeth — resists metal scale abrasion.
✅ Precision bore 0.025mm TIR — vibration-free operation at production speed.
✅ Full EN 10204 3.1 material traceability — meets audit requirements.
مکانها: Coil car chain, turnstile drive, threading table, exit conveyor. عملکرد: Convert motor torque into precise material feed and processing motion.
نصب شده: Danieli*, SMS Group*, Primetals*, Andritz* systems. *Compatibility reference only.
انتخاب کنید: 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.
نصب: LOTO → release chain → remove old sprocket → mount new (TL = rapid change) → align → tension 2-3% → lubricate → test.
مسائل: دندانههای زنجیر = چرخدنده فرسوده (هر دو را تعویض کنید). لرزش = ناهمراستایی/عدم تنظیم قطر داخلی. صدای بیش از حد = خشکی زنجیر. پرش زنجیر = زنجیر بلند + دندانههای فرسوده (هر دو را تعویض کنید).
Wollongong, NSW: “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.” ★★★★★
