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.
Platser: Coil car chain, turnstile drive, threading table, exit conveyor. Fungera: Omvandla motormomentet till exakt materialmatning och bearbetningsrörelse.
OEM: Danieli*, SMS Group*, Primetals*, Andritz* systems. *Compatibility reference only.
Välja: 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.
Installera: LOTO → lossa kedjan → ta bort det gamla kedjehjulet → montera det nya (TL = snabbväxling) → rikta in → spänn 2-3% → smörj → testa.
Problem: Kedjans löptänder = slitet kedjehjul (byt båda). Vibration = feljustering/borrhålskast. För mycket ljud = torr kedja. Kedjehopp = förlängd kedja + slitna tänder (byt båda).
Wollongong, NSW: “Precision sprockets matched OEM specs. Running well.” ★★★★★
Sydney, Nya Sydvästra Sydvästra USA: “Split hub saved hours during shutdown. Material certs provided.” ★★★★★
Brisbane, Queensland: “Consistent quality across multiple orders. Hardened teeth lasting well.” ★★★★☆
Adelaide, Sydafrika: “QD bushed on large shaft. Rapid installation, running true.” ★★★★★
Melbourne, VIC: “Professional documentation, competitive pricing, reliable supply.” ★★★★★
