✅ CNC precision teeth for accurate material feed positioning.
✅ HRC 40-50 hardened teeth — resists wood resin/bark abrasion.
✅ Split hub / QD for field replacement — minimises expensive downtime.
✅ Full EN 10204 3.1 material traceability — meets audit requirements.
Locations: Log deck chain, carriage drive, debarker, green chain, trim saw feed. समारोह: Convert motor torque into precise material feed and processing motion.
ओईएम: Wood-Mizer*, Helle*, EWD*, Linck* systems. *Compatibility reference only.
चुनना: 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 (split hub = no chain removal) → 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).
Launceston, TAS: “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.” ★★★★★
