Sawmill Equipment
Sawmill sprockets drive log deck chains, carriage feed mechanisms, debarker conveyors, and timber sorting systems. Operating in wet, resinous environments with heavy log impacts requiring 4140 steel, zinc-nickel coating, and split hub construction.

Advantages vs Inferior / Working Principle
✅ 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. Function: Convert motor torque into precise material feed and processing motion.
Compatibility / Selection
OEM: Wood-Mizer*, Helle*, EWD*, Linck* systems. *Compatibility reference only.
Select: 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 / Troubleshoot
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).
