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.
Locais: Coil car chain, turnstile drive, threading table, exit conveyor. Função: Converter o torque do motor em alimentação precisa de material e movimento de processamento.
OEM: Danieli*, SMS Group*, Primetals*, Andritz* systems. *Compatibility reference only.
Selecione: 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.
Instalar: LOTO → soltar a corrente → remover a roda dentada antiga → montar a nova (TL = troca rápida) → alinhar → tensionar 2-3% → lubrificar → testar.
Problemas: Corrente raspando nos dentes da engrenagem = pinhão gasto (substitua ambos). Vibração = desalinhamento/desalinhamento do furo. Ruído excessivo = corrente seca. Corrente pulando = corrente alongada + dentes gastos (substitua ambos).
Wollongong, NSW: “Precision sprockets matched OEM specs. Running well.” ★★★★★
Sydney, Nova Gales do Sul: “Split hub saved hours during shutdown. Material certs provided.” ★★★★★
Brisbane, Queensland: “Consistent quality across multiple orders. Hardened teeth lasting well.” ★★★★☆
Adelaide, Austrália do Sul: “QD bushed on large shaft. Rapid installation, running true.” ★★★★★
Melbourne, VIC: “Professional documentation, competitive pricing, reliable supply.” ★★★★★
