Oregon 28" Chainsaw Chain 3/8" Pitch .050" Gauge — 105 Drive Links, Lubritec & Blued Cutters

This Oregon replacement chain is engineered for reliable cutting on a 28" guide bar. It combines Lubritec lubrication reservoirs, blued corrosion-resistant cutters and an optimized cutter shape to deliver smoother starts, reduced friction and long wear life. The expanded top-plate and depth-gauge filing guides make field sharpening straightforward, while the OCS-01 steel tie straps add strength for demanding jobs on 50–100cc saws.

Will this chain fit my saw and guide bar?

Check three measurements: pitch, gauge and number of drive links. This chain is 3/8" pitch and .050" gauge with 105 drive links, which commonly fits 28" bars on mid-to-large professional and homeowner saws. Always confirm the saw manufacturer’s recommended drive-link count and bar length before ordering.

• Pitch: 3/8" — space between drive links
• Gauge: .050" (1.3 mm) — thickness that fits the bar groove
• Drive links: 105 — matches a 28" guide bar on many saws
• Recommended engine sizes: generally 50–100cc saws

How does Lubritec help during cutting and start-up?

Lubritec incorporates tiny lubricant reservoirs in the chain that hold oil where friction is highest. That stored lubricant reduces friction during the brief period before the saw’s oiling system reaches full flow, easing start-up wear and lowering heat in the drive area.

• Reservoirs deliver oil directly to high-friction contact points
• Reduces wear during initial minutes of operation
• Helps stabilize tie straps to reduce flex under load
• Promotes longer chain life with consistent lubrication

How easy is maintenance and sharpening in the field?

Oregon designed this chain with expanded top-plate and depth-gauge filing indicators to simplify accurate sharpening. Clear marker zones help you restore cutting geometry quickly with a round file, keeping tooth heights even and cutting performance consistent.

• Expanded filing indicators for clear visual reference
• Depth-gauge markers guide consistent raker settings
• Compatible with standard round files and a filing guide
• Reshaped cutters maintain efficient cutting between sharpenings

What performance and durability features should I expect?

The reshaped cutter profile slices through wood with improved efficiency, while blued cutters provide an extra layer of corrosion resistance for longer life. The OCS-01 steel used in tie straps enhances strength so the chain withstands heavier cutting tasks without premature deformation.

• Reshaped cutters for faster, more efficient cutting
• Blued cutters resist rust and preserve edge life
• OCS-01 steel tie straps for added durability and strength
• Standard cutter sequence for balanced feed and control

Who is this chain for? This Oregon 28" 3/8" .050" 105-drive chain is intended for owners of gas-powered chainsaws in the 50–100cc class who need a robust replacement for a 28" guide bar. It suits arborists, farmers, property managers and serious homeowners who want easier field sharpening, improved start-up lubrication and a corrosion-resistant cutting edge. Confirm pitch, gauge and drive-link count on your saw and bar to ensure proper fit before purchasing.
