Buying a replacement Husqvarna chainsaw chain comes down to three numbers — pitch, gauge, and drive-link count — and the most common mistake is ordering by bar length alone. Match all three numbers to the bar stamp and you’ll never install a wrong chain; a 20-inch replacement chain, for instance, is not a size, and two 20-inch bars can need different drive links. This guide covers every current Husqvarna model, charted, with a dedicated Rancher chain sizes section and the sharpening-versus-replace decision at the end.

A quick note on why this gets people stuck. Husqvarna fits at least four distinct pitch systems across its homeowner-to-pro range — 3/8” mini, .325”, 3/8” low profile, and full-size 3/8” — and gauge varies within each. Grab an Oregon box by eye at the counter and you’re rolling dice. Measure once, order right.

Husqvarna Chain Families: H-Series and X-Cut Explained

Husqvarna names its chains with an H prefix and a number; the bigger the number, generally the bigger the pitch and cutter. Three families cover nearly everything a homeowner or landowner will touch.

• H25, H30, H32, H35 — the .325” pitch family in .050” gauge. These fit the mid-range Rancher saws; the 450 Rancher’s stock chain is the H30 class, and full-chisel H30 variants cut noticeably faster in clean wood than the semi-chisel H32-type patterns.
• H46, H47, H48 — the 3/8” low-profile family, most commonly in .050” and .058” gauge. These fit the 455 and 460 Rancher, the 555, and the 562/572 XP saws.
• 3/8” mini chains for the small saws — the 120, 130, and 135 run this low-profile mini pitch, a distinct system smaller than 3/8” low profile, with the H37-type being the common pattern.

X-Cut is the newer premium layer: K-series bars paired with factory-sharpened, harder-wearing chains that now come fitted on many of Husqvarna’s current saws out of the box and are sold as replacements under their own model numbers (the C85 and S95 are typical examples for the 3/8-class and mini-class systems respectively). An X-Cut chain still fits by the same pitch-gauge-drive-link logic; the label is about cutter durability out of the package. If you’re weighing aftermarket chains at all, our best chainsaw chains round-up puts Husqvarna, Oregon, and Stihl chains against each other.

One last part of the system most buyers forget: the chain only works if the sprocket and bar share its pitch. A rim sprocket stamped 3/8 cannot drive a .325 chain, and it won’t accept .325’s narrower gauge either. If you’ve bought a used Husqvarna with unknown history, pull the clutch cover, read the sprocket stamp, and confirm the bar’s groove gauge before you order anything. Mismatched sprocket-and-chain combos destroy the clutch drum quietly and expensively.

Bottom line: read the first letter and last two numbers of your chain — an H30-72 is .325” pitch at 72 drive links — and the H-family tells you which saw it fits.

How to Measure Pitch, Gauge, and Drive Links Without a Kit

You can fully spec a replacement chain from a screwdriver, a tape, and patience. Pitch is the distance between three consecutive rivets divided by two. Measure center-to-center across any three rivets — call it D — and pitch is D/2; a 9/16” span across three rivets means a 3/8” chain. Fractional chains are close enough in raw numbers that the common pitches (.325”, 3/8”, 3/8” mini) are easiest to identify by knowing the family: if your saw list says 450, use .325.

Gauge is the thickness of a drive link, which is the thickness of the slot it rides in. Slide a feeler gauge or a drill bit between two drivelink pads and the bar’s groove isn’t needed — measure the drive link itself, or simpler: count the grooves. The practical method: drop the old chain on the bench and measure a drive link’s width across its widest section with calipers or a gauge card; .043”, .050”, .058”, and .063” separate cleanly at a glance. If you have no tools, the chain’s stamp is usually on the drive link itself — one number stamped on the plate, one on the link.

Drive links are the easiest: count them. Lay the chain flat and count links nose to tail, or read the packaging if it survives. The count is what makes the same “18-inch chain” differ across bars, so count every time you buy new.

Bottom line: pitch from three rivets, gauge from a drive link, drive-link count from counting — three measurements make up for every marketing label on the box.

Rancher Chain Sizes: 450, 455, and 460 Fitment

The three Rancher saws split into two chain systems, and this is the table most readers came for. The Husqvarna 450 Rancher wears .325” pitch; the 455 and 460 wear 3/8” low profile. Our full Husqvarna Rancher three-way comparison covers the saws themselves, but the chain numbers live here.

Model	Pitch	Gauge	18” drive links	20” drive links	Common H-series
450 Rancher	.325”	.050”	72	72	H30/H32L
455 Rancher	3/8” low profile	.050”	typically 68	typically 72	H47-pattern
460 Rancher	3/8” low profile	~.058”	typically 68	typically 72	H46-pattern

Two hedged practical notes here, straight from cutting with all three. First, the 460’s .058 gauge means its chain is stocked in smaller quantities than the .050 everyone else wears — order the 460’s reel by count, and buy two at once. Second, the drive-link counts above assume the stock Husqvarna bar; an aftermarket bar in the same length can shift a count by a link or two, which is why “count before you buy” is repeated through this entire guide.

On cutter styles for Rancher saws: semi-chisel patterns hold their edge better through bark, dirt, and punky preseason wood, which makes them the default for firewood bucking. Full-chisel H30-class chains on the 450 cut visibly faster in clean, seasoned softwood — pine, poplar, fir. If you cut both, keep a semi on the saw and a chisel in the truck.

Bottom line: the 450 Rancher is a .325/.050 saw with 72 drive links at 18 inches; the 455 runs 3/8 LP at .050; the 460 runs 3/8 LP at about .058 — gauge is where the three stop sharing.

Husqvarna Chainsaw Chain Replacement Chart by Model

This is the full-model quick reference, from the smallest homeowner saws to the big Ranchers. Where manufacturers changed components across production runs, the numbers carry “typically” — when in doubt, count your old chain.

Model	Pitch	Typical gauge	Stock bar(s)	Typical drive links
120 Mark II	3/8” mini	narrow (bar class)	14” / 16”	mid-50s at 16”
130	3/8” mini	narrow (bar class)	14” / 16”	mid-50s at 16”
135 Mark II	3/8” mini	typically .050-class	16”	mid-to-high 50s
435 e-series II	.325”	.050”	16” / 18”	66 at 16” / 72 at 18”
450 Rancher	.325”	.050”	18”	72
455 Rancher	3/8” low profile	.050”	18”	typically 68
460 Rancher	3/8” low profile	~.058”	20”	typically 72

Bar length plays straight into drive-link count, so the mini table below generalizes it: longer bar, more links. Keep in mind that pitch and gauge never change with bar length — only the link count does. The full DL counts for every bar range live in our chain size chart.

Bar length	.325” (.050”) DL	3/8” low profile DL	3/8” mini DL
14”	~60	~52	mid-40s
16”	66	~56–58	mid-50s
18”	72	typically 68	—
20”	72 (450 max bar)	typically 72	—

A word on the small saws because the internet argues about them constantly. The 120 Mark II, 130, and 135 take the low-profile 3/8-inch mini pitch — a smaller, narrower system than the 3/8-inch low profile on Rancher saws, and not interchangeable with it. These small saws ship varied factory fitments across markets — some with 14-inch bars, some 16 — and gauge options vary with the bar that came in the box, so the honest advice is: the pitch is 3/8” mini, the bar is 14 to 16 inches, count the drive links before ordering. Newer small-saw replacements, including X-Cut patterns, remain available from dealers and online.

Bottom line: the chart gets you within a pitch and a gauge, but the drive-link count always comes from the bar stamp or an actual count of the old chain.

When to Sharpen vs When to Replace a Husqvarna Chain

Sharpening is routine; replacing is rare. A sharp Husqvarna chain spits chips the size of pencil erasers; a dull one produces sawdust and makes you lean into the cut. That single visual tells you more than any hour count. In seasoned oak, expect to file every two tanks; in dirty, bark-locked winter wood, every tank.

The sharpening process takes about five minutes with the right round file. File sizes follow pitch: the .325” chains on Rancher saws typically take a 5/32-inch file, and the 3/8-inch chains take a larger file per the packaging — Husqvarna prints it on every box, and a filing guide keeps the top-plate angle right if you’re new to it. Two passes per cutter, and count your passes so the chain cuts straight. If you’re learning the whole process, our chainsaw sharpening walkthrough breaks it down with angles and raker depth. More broadly, if the issue is chain care rather than fitment, the general chainsaw chain guide covers the cross-brand version of this material.

Rakers, the depth gauges riding ahead of each cutter, deserve a mention because a chain can be razor sharp and still cut nothing if its rakers ride high. Husqvarna’s chains come with rakers set at the factory, and typical maintenance is checking them every three to five sharpenings with a flat file and depth-gauge tool, dropping them to the chain’s stamped spec. Skipped rakers show up as the saw “biting” only in wet softwood and skating on oak — a confusing symptom that owners blame on dull cutters.

Replace the chain when you hit these conditions, in rough order of frequency:

• Cutters worn to the marked depth, or visibly past two-thirds of original height
• Teeth cracked, bent, or pulled from damage — sharpening can’t fix geometry
• Chain has hit a rock, dirt, or a nail and shows gray, heat-marked cutters after a filing
• The chain pulls sideways even after rebuilding the cutter angles evenly
• You can’t hold tension: the chain tails and loosens within minutes of a fresh adjustment

Worn chains are also a bar-killer. Running a chain past its wear limit accelerates a bar’s groove into a sloped slot that eats the next chain faster, so a $20 replacement chain routinely saves an $80 bar. The routine removal-and-reinstall process — including tensioning a fresh chain — is its own skill, covered step by step in our chainsaw chain replacement guide.

Bottom line: file when chips turn to dust and sawdust appears, replace when cutters reach their depth marks or the chain gets visibly damaged — and never run a worn chain into a good bar.

The Five-Minute Chain Shopping Procedure

Walk into any dealer or open any seller page with these five steps and you won’t buy wrong. First, read the pitch and gauge stamped on the bar, usually near the slot’s back end. Second, count drive links on the current chain. Third, write down the saw model — dealers cross-reference it if the bar is too worn to read. Fourth, decide semi-chisel versus full-chisel based on your wood: dirty firewood takes semi-chisel, clean seasoned softwood takes full chisel for speed. Fifth, buy two chains at once, because a dull chain at mid-afternoon is the cheapest lesson in inventory management you will ever learn.If you’re choosing between Husqvarna-family saws in the first place — 435 versus 450, 120 versus 135 — the value comparisons in Best Husqvarna Chainsaws already sort them, and the wider gas market is ranked in Best Chainsaws of 2026. Both put chain availability into the value math, because an otherwise great saw with rare chain fitment costs more to run than the sticker shows.

Bottom line: match pitch and gauge from the stamp, count drive links, buy two chains at once — and the replacement process takes eleven minutes, not a trip back to the dealer.

Frequently Asked Questions

What size chain does a Husqvarna 450 Rancher use?

The 450 Rancher runs .325-inch pitch, .050-inch gauge. An 18-inch bar takes a 72-drive-link chain, typically the Husqvarna H30 class (H30-72), and a 20-inch bar also uses 72 drive links on the stock bar. Match pitch, gauge and drive-link count — never order by bar length alone.

What chain does the Husqvarna 120 Mark II take?

The 120 Mark II uses a low-profile 3/8-inch mini pitch chain — a smaller pitch than the 3/8 low profile on Rancher saws — commonly on 14 to 16-inch bars at a narrow gauge. Count the drive links on the old chain or check the bar stamp; on most 16-inch setups that lands in the mid-50s.

Is the Husqvarna 455 Rancher 3/8 chain .050 gauge?

Yes. The 455 Rancher runs 3/8-inch low-profile chain at .050-inch gauge, typically 68 drive links for an 18-inch bar and 72 for a 20-inch bar on the stock Husqvarna bar. A .058 chain will not seat in the stock bar's groove.

How often should I sharpen a Husqvarna chain?

File after every one to two tanks of fuel in hardwood and hardwood bark, and sooner in dirty wood. A chain needs sharpening when chips turn to dust, when the saw starts cutting crooked, or when you have to push on the handle to keep the cut moving.

When should I replace a chainsaw chain instead of filing it?

Replace the chain when cutters are worn to the depth marks stamped or visibly worn toward the link, when teeth are cracked or bent, when the chain has hit dirt or rock twice in a season, or when it has been sharpened past about two-thirds of its original cutter height.
