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.
Konumlar: Coil car chain, turnstile drive, threading table, exit conveyor. İşlev: Motor torkunu hassas malzeme besleme ve işleme hareketine dönüştürün.
OEM: Danieli*, SMS Group*, Primetals*, Andritz* systems. *Compatibility reference only.
Seçme: 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.
Düzenlemek: LOTO → zinciri serbest bırak → eski dişliyi çıkar → yenisini tak (TL = hızlı değişim) → hizala → 2-3% gerdir → yağla → test et.
Sorunlar: Zincir dişlerinin takılması = aşınmış dişli (her ikisini de değiştirin). Titreşim = yanlış hizalama/silindir çapının bozulması. Aşırı gürültü = kuru zincir. Zincir atlaması = uzamış zincir + aşınmış dişler (her ikisini de değiştirin).
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, Güney Avustralya: “QD bushed on large shaft. Rapid installation, running true.” ★★★★★
Melbourne, VIC: “Professional documentation, competitive pricing, reliable supply.” ★★★★★
