Stihl 26RS Rapid Super Chainsaw Chain — 18-inch bar, .325 pitch, .063 gauge, chromized cutters

The Stihl 26RS 74 Rapid Super is a genuine Stihl replacement chainsaw chain designed for 18" bars with .325" pitch and .063" gauge, built for fast, smooth cutting and long-lasting edge life.

This Rapid Super chain from Stihl fits 18-inch guide bars and matches a .325" pitch with a .063" (1.6 mm) gauge — a common combination for lightweight to midweight cutting tasks. It’s manufactured with chromized cutter teeth to resist wear and maintain performance under frequent use. If you’re replacing a chain or stocking common sizes for general cutting, pruning, or firewood work, this model is a direct-fit genuine Stihl option when your bar and sprocket match the specified pitch and gauge.

How do I confirm this chain fits my saw and bar?

Verify three things: bar length, pitch, and gauge. Measure the bar to ensure it’s 18" (or labeled 18"), check the pitch stamped on the old chain or sprocket is .325", and confirm the gauge is .063". If any stampings are missing, count drive links and compare to your bar’s specification.

• Bar length: 18" nominal compatible with 18" Stihl bars
• Pitch: .325" required for sprocket engagement
• Gauge: .063" for correct fit in the bar groove
• When unsure, bring the old chain or consult dealer for exact match

What cutting tasks is the Rapid Super chain best suited for?

The Rapid Super design balances speed and control, making it good for general-purpose cutting like small trees, limbing, and firewood. It’s suitable for frequent hobbyist use and those who need reliable, durable cutters without moving to heavy professional chains.

• Firewood cutting and small to medium tree felling
• Limbing and pruning around the yard
• Suitable for gasoline-powered saws that accept .325"/.063" chains
• Durable chromized teeth reduce wear on abrasive wood

How should I maintain and sharpen this Stihl chain?

Keep the chain properly tensioned, well-lubricated, and regularly sharpened to preserve cutting performance. Use a round file of the correct diameter for .325" pitch cutters and inspect for damaged links or bent drive teeth; replace the chain if damage compromises safety.

• Check and adjust tension before each use for safe tracking
• Use bar oil consistently to reduce wear and overheating
• File cutters to the correct angle and depth with a .325"-compatible file
• Replace if rivets loosen or teeth become chipped beyond sharpening
