Overview

The STIHL 20″ (50 cm) Chainsaw Guide Bar (1.6 mm / 0.063″ Gauge, 3/8″ Pitch) is a professional-grade replacement cutting attachment designed for mid-to-high displacement STIHL petrol chainsaws. Engineered for forestry, timber bucking, firewood processing, and tree felling, this guide bar provides high bending resistance, smooth chain rotation, and optimal power delivery under continuous heavy cutting loads.

Constructed from three high-grade steel plates electrically welded together, it features a lightweight center plate cutout that balances stiffness with ergonomic handling. It incorporates STIHL’s integrated Ematic oil channel system, which directs chain lubricant straight to the bar rails and saw chain drive links to minimize friction, lower thermal degradation, and reduce bar oil consumption by up to 50%. Equipped with a fully sealed nose sprocket, it ensures smooth chain movement around the bar tip with minimal power loss.

Key Features & Benefits

• High-Strength Laminated Steel: Electrically welded three-layer steel plate construction provides stiffness and flex resistance.

• Ematic Lubrication System: Directs oil precisely to the wear surfaces, reducing thermal friction and extending chain lifespan.

• Induction-Hardened Rails: Heat-treated bar edges resist tracking wear and rail spreading from high chain speeds.

• Sealed Nose Sprocket: Precision sprocket bearing at the tip reduces friction, power loss, and maintenance requirements.

• Versatile Professional Length: 20-inch (50 cm) cutting capacity provides an ideal balance of reach, power transfer, and maneuverability for mid-sized logging.
