This 16-inch alloy guide bar is a direct replacement specifically designed for STIHL chainsaw models including MS170, MS171, MS180, MS181, and their classic counterparts 017, 018, 019T, 021, 023, and 025. It features a 3/8" Low Profile (Picco) chain pitch, .050" (1.3mm) gauge thickness, and 55 drive links, ensuring precise fitment for your saw. The laminated steel construction with a sprocket nose provides excellent durability and reduced wear, while the narrow nose design offers superior maneuverability for limbing and boring operations.

The bar is compatible with STIHL's 3005 small mount system and uses a 3/8" Picco drive sprocket on the saw.
Technical Profiles & Materials
Precision 16-Inch Compatibility – The 16-inch bar length is the standard upgrade from the MS170's factory 12-inch or 14-inch bars, delivering a balanced combination of reach and cutting capacity for firewood, pruning, and general property maintenance. The bar pairs perfectly with 55-drive-link chains.
3/8" LP (Picco) Pitch Configuration – Designed for the 3/8" Low Profile chain system, which is the standard specification for MS170-class saws. This pitch provides smooth cutting performance with reduced vibration and lower kickback potential compared to larger pitch chains.
.050" Gauge Specification – This bar features the .050" (1.3mm) gauge, which matches the chain specifications for MS170 and compatible models. Some manufacturers also offer .043" (1.1mm) gauge options for this platform, so verify your current chain gauge before ordering to ensure correct fitment.

Products Application
Firewood Cutting
The 16-inch guide bar provides an excellent balance of cutting capacity and control for processing small to medium firewood logs. The 3/8" LP chain system delivers smooth, efficient cutting with reduced kickback risk, making it suitable for residential firewood preparation and storm cleanup.
Tree Pruning & Limbing
This bar length is ideal for pruning branches and removing limbs up to approximately 14 inches in diameter. The Rollomatic design with a narrow sprocket nose enables efficient limbing and boring cuts, and the narrow nose helps reduce kickback tendencies. The durable steel construction and lighter weight compared to larger bars reduce operator fatigue during extended pruning sessions.
General Property Maintenance
Suitable for a wide range of residential and light commercial property maintenance tasks, including clearing brush, cutting fence posts, and general landscaping. The 3/8" LP system is the standard specification for STIHL entry-level saws and provides reliable performance for everyday cutting needs. Many aftermarket bars are built with lightweight materials for high performance with minimum vibration.

FAQ
Q: How do I confirm this guide bar fits my chainsaw?
A:Check your chainsaw model number on the housing. This bar fits STIHL MS170, MS171, MS180, MS181, MS210, MS211, MS230, MS250, and many compatible models listed above. Verify your current chain specifications (16-inch length, 3/8" LP pitch, .050" gauge, and 55 drive links) to ensure compatibility. According to STIHL, the MS170 supports 16" Rollomatic E bars with the 3005 mount system. Some saws may accept .043" gauge chains instead of .050", so verify your current chain gauge before ordering.
Q: What chain do I need with this guide bar?
A: This 16-inch guide bar pairs with a 3/8" LP (Picco) chain with .050" gauge and 55 drive links. Compatible chains include STIHL 61PMM3-55 (OEM 3610-005-0055), STIHL 63PM-55, Oregon 90PX055, and various aftermarket equivalents. If your bar uses .043" gauge, use STIHL 61PMM3-55 or similar chains with that specification. Always confirm drive link count (55) matches your existing chain.
Q: What is the difference between .050" and .043" gauge guide bars?
A: The gauge refers to the thickness of the groove where the chain's drive links sit. .050" (1.3mm) is the standard thicker specification, while .043" (1.1mm) is a thinner alternative commonly used on entry-level STIHL saws. Using the wrong gauge will cause the chain to fit too loosely or too tightly, compromising safety and performance. Verify your current chain gauge before ordering-many MS170 bars use .043" as factory standard, while the .050" option is also widely
