Oregon is the world’s largest aftermarket chainsaw chain manufacturer, producing replacement chains for virtually every major brand. Whether you own a Stihl, Husqvarna, Makita, or DeWalt chainsaw, there’s an Oregon equivalent that will fit. This guide breaks down their numbering system, major series, and exactly which Oregon chain works with your saw.
Understanding Oregon Chain Numbers
Every Oregon chain model has a code that tells you its specifications. Take the model 91PX052E as an example:
- 91 = Series (determines pitch and typical use)
- PX = Tooth type (PX = PowerCut standard, VPX = VersaCut for smoother cutting, TXL = SpeedCut for faster cutting)
- 052 = Drive link count (the number of links on the chain)
- E = Safety feature (E = Oregon safety standard)
The series number is the most important — it determines pitch (the distance between teeth) and gauge (the thickness of the drive links that slot into your bar’s groove).
Oregon Chain Series Reference Table
| Series | Pitch | Gauge | Tooth Type | Profile | Best For |
|---|---|---|---|---|---|
| 90PX | 3/8″ LP | .043″ | PowerCut standard | Low-profile | Mini chainsaws, small battery saws (20–25cc) |
| 91PX | 3/8″ LP | .050″ | PowerCut standard | Low-profile | Small-to-mid petrol and battery saws (30–50cc). Most popular aftermarket series. |
| 91VXL | 3/8″ LP | .050″ | VersaCut (low kickback) | Low-profile | Same use as 91PX, but smoother and safer cutting. |
| 95VPX | .325″ | .050″ | VersaCut (low kickback) | Full-profile | Mid-range petrol saws (40–60cc), professional domestic use. |
| 95TXL | .325″ | .050″ | SpeedCut (fast cutting) | Full-profile | Same as 95VPX but faster. Favoured for felling and bucking. |
| 21LPX | .325″ | .058″ | PowerCut standard | Full-chisel | Professional mid-range saws, heavy commercial work. |
| 72LPX | 3/8″ | .050″ | PowerCut standard | Full-chisel | Professional saws 60cc+, felling and bucking. |
| 73LPX | 3/8″ | .058″ | PowerCut standard | Full-chisel | Heavy-duty professional work, dull wood and demolition. |
| 75LPX | 3/8″ | .063″ | PowerCut standard | Full-chisel | Large professional saws 75cc+, arboricultural and milling work. |
The key difference between low-profile (LP) and full-profile chains: full-profile chains cut faster but produce more kickback. Low-profile chains are safer and standard on battery saws and entry-level petrol models.

Note: Always verify the drive link count on your old chain before ordering. The bar length printed on your chainsaw tells you approximately how many drive links you need, but exact count varies by manufacturer.
Oregon Tooth Types Explained
PowerCut (standard): The baseline Oregon tooth design. Fast, affordable, reliable. Found on 90PX, 91PX, 72LPX, 73LPX, 75LPX.
VersaCut (low-kickback): Reduced-height tooth profile with aggressive cutters. Produces less kickback and vibration — ideal for handheld work and safety-conscious users. Series: 91VXL, 95VPX. Slightly more expensive than PowerCut but worth it for comfort and safety.
SpeedCut (fast-cutting): Aggressive tooth geometry for maximum cutting speed. Produces higher kickback and requires more skill to control. Favoured by professional fellers doing production work. Series: 95TXL. Most expensive Oregon option.
Oregon PowerSharp System
Some Oregon chains feature the PowerSharp integrated sharpening system. These chains have replaceable sharpening stones built into the nose bar — you rotate the nose bar in your chainsaw to self-sharpen the chain without removing it. It’s a gimmick for casual users; professional arborists and loggers still hand-file or take chains to a shop. Standard Oregon chains (like 91PX) work better for most people.
How to Read an Oregon Chain Box
When you buy an Oregon chain in a box, the label includes everything you need:
- Model number (e.g. 91PX052E) — tells you series, tooth type, and drive link count
- Pitch and gauge — printed separately for reference
- Compatibility chart — lists which brands/models this chain fits
- Drive link count — the actual number of links
- Lot number and date — for warranty and traceability
The most critical step: always count your old chain’s drive links and cross-reference them with the box. A 91PX052 (52 drive links) will not fit a bar designed for 91PX056 (56 drive links).
Oregon Chain Care and Maintenance
Oregon chains are aftermarket, but maintenance is identical to OEM chains:
- Keep chain tension correct — you should barely be able to pull the chain away from the bar at the midpoint
- Check tension before every use; it loosens as the bar wears
- Maintain adequate bar oil — a dry or low-oil chain will dull, bind, and break
- Sharpen regularly — a dull chain works harder, generates heat, and can snap
- Replace after 50–100 hours of use or when teeth are worn to the tie-strap level
Oregon chains typically last 50–80 hours before needing replacement, depending on wood type and maintenance. Professional users replace them more frequently (every 40 hours) for consistent cut quality.
Oregon vs. OEM Chains — Is Aftermarket Worth It?
Many chainsaw owners assume OEM (original manufacturer) chains are better. In reality, Oregon aftermarket chains are often superior:
- Better tooth geometry — Oregon invests in R&D; OEM chains are often generic
- Lower cost — 30–50% cheaper than OEM chains with the same performance
- Wider availability — stock at every major tool supplier
- Better warranty — Oregon backs their chains; OEM warranties are often limited
- Tooth type choices — you can select PowerCut, VersaCut, or SpeedCut; OEM brands rarely offer this
The downside: Oregon doesn’t make chains for every single brand. Check compatibility before buying.

Frequently Asked Questions
Can I use any Oregon chain in my Stihl?
No. Oregon chains must match your Stihl’s pitch, gauge, and drive link count. A Stihl MS180 (3/8″ LP pitch) needs a 91PX series chain; a MS261 (.325″ pitch) needs a 95VPX. Cross-reference your model in the chart above.
Are Oregon chains compatible with Husqvarna?
Yes. Husqvarna saws use standard pitch and gauge specs that Oregon covers with their full range. A Husqvarna 445 (.325″ pitch) uses an Oregon 95VPX chain, just like many other mid-range brands.
Which Oregon chain is fastest?
The 95TXL SpeedCut is the fastest-cutting chain Oregon makes. It has aggressive tooth geometry designed for professional fellers. However, it produces more kickback and requires skill to use safely. For most users, 91VXL VersaCut (on small saws) or 95VPX VersaCut (on mid-range saws) offers a better balance of speed and safety.
What’s the difference between 91PX and 91VXL?
Both are 3/8″ LP pitch, .050″ gauge chains from Oregon. The 91PX is standard PowerCut (basic, affordable). The 91VXL is VersaCut (reduced kickback, safer, smoother). The 91VXL costs slightly more but is worth it if you use your saw regularly.
Can I put a 72LPX chain on a small Stihl?
No. The 72LPX is 3/8″ full-profile pitch — it won’t fit a bar designed for 3/8″ LP (low-profile). The pitch measurement is the same, but the chain physically won’t sit in a low-profile bar groove. Never force a chain onto a bar.
How often should I replace my Oregon chain?
Replace when teeth wear to the tie-strap level (visible groove in the tie-strap metal) or after 50–100 hours of use. Professional users replace every 40 hours for optimal cutting quality. Home users might get 60–80 hours from a single chain.
Are Oregon chains better than Stihl or Husqvarna OEM chains?
They’re competitive. Oregon chains are often sharper out of the box and offer more tooth type options (PowerCut, VersaCut, SpeedCut). OEM chains are engineered for your specific saw but typically cost 30–50% more. For most users, Oregon is the better value.
