Oregon 28" Chainsaw Chain — 3/8" Pitch .050" Gauge, 91-Link Skip-Tooth with LubriTec for Long Bars

Oregon's 28" chainsaw chain with 3/8" pitch, .050" gauge and 91 drive links is a heavy-duty skip-tooth replacement designed for long bars and larger saws, built for smoother chip flow, easier sharpening, and extended wear resistance.

This replacement chain is engineered to fit 28-inch guide bars on larger saws (recommended for 50–100cc engines) and to handle demanding cutting tasks. It pairs a skip-cutter sequence for improved chip evacuation with LubriTec reservoirs that retain oil where friction is highest, plus blued cutters and a specially formulated steel for longer service life. The chain also includes filing guides to simplify maintenance and keep cutting performance sharp between professional tune-ups.

How does this chain improve cutting on a long 28" bar?

The skip-tooth cutter layout creates larger gullets between cutters, allowing sawdust and chips to clear rapidly when cutting big timber or when using a long bar. Faster chip evacuation reduces clogging and keeps the cutting path clear, which helps maintain consistent cutting speed and reduces strain on the saw.

• Skip sequence gives larger chip clearance for big logs and long bars
• 3/8" pitch and .050" gauge balance strength and cutting efficiency
• 91 drive links matched to 28" guide bars for proper fit

What features make this chain easier to maintain and sharpen?

Oregon added expanded top-plate and depth-gauge filing markers so you can quickly restore cutter geometry and maintain safe depth settings between sharpenings. The reshaped cutters maintain sharpness and make each filing pass more predictable, which reduces guesswork when restoring cutting faces and gullet profiles.

• Visible filing indicators on top plates and depth gauges for accurate sharpening
• Reshaped cutter profile simplifies consistent filing strokes
• Skip-tooth design reduces the number of cutters to sharpen compared with full complement chains

Why does LubriTec and blued cutter treatment matter for durability?

LubriTec reservoirs trap and hold lubricant in the high-friction zones between chain and bar so oil is present right where it's needed, including during cold starts before the saw's pump reaches full flow. Bluing on the cutters adds a corrosion-resistant surface layer while the OCS-01 grade steel gives the cutters greater toughness for extended wear life.

• LubriTec reservoirs reduce friction and help protect against early wear
• Blued cutters resist rust for longer shelf and field life
• OCS-01 steel increases cutter durability under heavy use

Will this chain fit my saw and what should I verify before ordering?

Confirm your guide bar measures 28 inches and that your saw accepts a 3/8" pitch with a .050" gauge chain. Also verify the chain requires 91 drive links—if any of those measurements differ, choose a matching Oregon part to ensure safe, reliable operation.

• Measure your guide bar length and note the stamped pitch/gauge information
• Count or confirm the required drive link number (91 for this chain)
• Recommended for 50–100cc saws; check manufacturer compatibility if unsure

Who this chain is for: This Oregon 28" skip-tooth chain suits professional arborists, loggers, and homeowners with large-displacement chainsaws who need a durable replacement that improves chip clearance and simplifies field sharpening. Choose it if you run long bars, cut large-diameter wood, or want a chain treated for corrosion resistance and improved lubrication retention.
