20" BAR SN 3/8-063 W

Overview

The STIHL ROLLOMATIC E Super Guide Bar (30030029421) is designed for professional chainsaw applications requiring precision bar-nose work, including limbing and boring operations.

Technical Features

• Solid-machined high-grade steel body with milled groove: Provides a rigid, durable rail structure that maintains consistent chain alignment under demanding cutting conditions.
• Replaceable sprocket nose assembly, riveted in place: The nose unit can be swapped out independently of the bar body, extending the overall service life of the bar and reducing total replacement costs.
• Integrated sprocket within the replaceable nose assembly: The sprocket carries the saw chain continuously from the top to the bottom of the bar, reducing friction-based wear compared to a solid-nose bar design.
• Narrow nose profile: The sprocket-integrated construction allows the bar nose to be manufactured considerably narrower than solid-nose alternatives, improving maneuverability in tight cutting situations.
• Reduced kickback tendency: The narrow nose geometry limits the kickback zone contact area, consistent with STIHL's design intent for safer bar-nose operations.
• 3/8" pitch chain compatibility at .063" gauge: Matches a widely used STIHL chain specification, ensuring straightforward chain sourcing and replacement in the field.

Applications

• Limbing: The narrow nose profile and reduced kickback tendency make this bar well-suited for removing branches from felled or standing timber.
• Boring cuts: The narrow, sprocket-tipped nose allows controlled plunge cuts into material, a technique used in felling and precision bucking work.
• Extended bar-nose use: The replaceable sprocket nose is specifically advantageous in work cycles where the bar nose is engaged frequently, distributing and minimizing localized wear.
• General professional felling and bucking: The 20" bar length and high-grade steel construction support sustained use in forestry and arboricultural applications.
