Oregon® R55 Micro-Lite™ 90SG Replacement Saw Chain, 55 Drive Links, 16

Oregon® Micro-Lite™ 90SG Replacement Cutting Chain is made for small saws and features a chamfer-chisel cutter design that outcuts competitive chains. 90SG cuts a narrow kerf, requiring less power from the saw than standard chains to make the same cut. Micro-Lite™ 90SG is a low-vibration/low-kickback chain which meets both the ANSI (U.S.) and CSA (Canadian) low-kickback requirements. This chain is ideal for homeowners or consumer users, and is equally well suited for commercial cutters such as arborists and orchardists. Micro-Lite™ 90SG is designed for use on electric saws with bars up to 16" (41 cm), and on small gasoline-powered saws up to 2.5 cubic inches (41cc) with bars up to 14" (35 cm). 90SG is compatible with all existing 91-type drive sprockets, and its narrow .043" gauge requires the use of a Micro-Lite™ bar. 90SG chain is part of a Micro-Lite™ narrow-kerf cutting system that requires less power from the saw to cut than standard cutting systems.

• LubriWell™ oil holes help carry oil around the full length of the guide bar's groove.

Special Features:

Micro-Lite™

• Micro-Lite™ is the name for our "narrow-kerf" chain-and-bar cutting systems. Cutting a narrower kerf allows your saw to cut faster and more efficiently. Use a Micro-Lite™ chain in team with a Micro-Lite™ bar for maximum results.

Vibe-Ban™

• Vibe-Ban™ is the name for our family of "low-vibration" chains, designed and built with features that will reduce the risk of vibration-related injury.

LubriLink™ and Lubriwell™

• A tie-strap reservoir and a drive-link hole, respectively. These simple features help keep oil where it's needed and improve the lubrication of your bar and chain for better performance and longer life.

Benefits:

Chamfer-chisel cutter shape

• Outstanding performance, fast and efficient cutting
• Excellent stay-sharp
• Smooth feel during use, smooth cut surfaces
• Reduces the tendency of saws to "skate"

Vibe-Ban™ low-vibration design

• Reduces the risk of vibration-related injury

Narrow Micro-Lite™ kerf (.221")

• Less power is required to make the same length of cut
• Helps the saw cut faster

Narrow 1.1mm (.043") gauge and weight reducing slots in the guard tie straps

• Less power is required to drive the chain
• Lighter weight, helps minimize user fatigue*

*Micro-Lite™ bar-and-chain combinations are approximately 15% lighter than standard combinations

Lubrilink™ tie straps and Lubriwell™

• Improved chain and bar lubrication, helps keep oil drive links where it's needed, reduces volume of oil required

Tall cutter shape, fits 4.5 mm round file

• Makes sharpening easier

Bumper tie straps and ramped depth gauges

• Low kickback, meets ANSI and CSA standards

Aft position of top plates

• Stabilizes the cutter for faster smoother cutting

Forward-pointing spear stamped on the cutters and tie straps

• Identifies 90SG as a low-vibration chain
• Indicates the proper chain-cutting direction

Witness marks on each cutter's top plate

• Makes it easier to hold the file at the correct angle during sharpening

Drive links are now coined from a heavier-gauge steel than our previous 90SG and spin it into loops

• Makes it easy to break 90SG chain from reels
• Helps reduce stretch.
