Husqvarna’s operator manuals list the chain pitch, gauge and drive-link count for each bar length, and many Husqvarna saws take more than one chain type. This guide uses those manuals and Husqvarna UK’s chain pages.
It covers the 135, 235, 440 and Rancher petrol saws and the 120i, 340i, 540i XP and 542i XP battery saws. Where we have not checked a model against a Husqvarna source, the table says so.

Husqvarna Rancher Series Explained
Husqvarna’s manuals list several chain options for each Rancher, by pitch, gauge and bar length. The figures below come from those manuals and Husqvarna UK’s chain pages.
445 Rancher vs 450 Rancher vs 455 Rancher
- 445 and 450 Rancher: .325″ chain in 1.3 mm (.050″) or 1.5 mm (.058″). 13″ = 56 DL, 15″ = 64, 16″ = 66, 18″ = 72; a 20″ bar is 78 or 80 DL depending on the manual edition.
- 455 Rancher: .325″ (1.3 or 1.5 mm, 13–20″, 20″ = 80 DL) or 3/8″ (1.5 mm in the global manual; the US/Canada manual also lists 1.3 mm) at 15″ = 56, 16″ = 60, 18″ = 68, 20″ = 72, 24″ = 84. Husqvarna UK lists the 455 Rancher with a 45 cm (18″) bar and H25 (.325″) chain.
- 460 Rancher: the same .325″ and 3/8″ options and drive-link counts as the 455.
Because these saws take more than one pitch and gauge, read the figures stamped on your bar, or count your old chain, before ordering.
Which Pitch Does Your Rancher Use?
The 440, 445 and 450 manuals list only .325″ chain. The 455, 460 and 560 XP manuals list both .325″ and 3/8″ options, and the 550 XP Mark II is .325″ only. We have not checked the 345 against a Husqvarna source.
Husqvarna Battery Chainsaw Chains
120i and 340i
- 120i: 3/8″ mini, 1.1 mm (.043″), Husqvarna H38 chain; the manual lists a 12″ bar with 45 drive links.
- 340i: 3/8″ mini, 1.3 mm (.050″), Husqvarna S93G chain; 12″ = 45, 14″ = 52, 16″ = 56 drive links.
The two use different gauges (1.1 mm and 1.3 mm), so their chains are not interchangeable even at the same length.
540i XP and 542i XP
- 540i XP: .325″ mini, 1.1 mm (X-PRECISION SP21G) at 12 / 14 / 16″ = 51 / 59 / 64 DL; 3/8″ mini, 1.3 mm (S93G) at 12 / 14 / 16″ = 45 / 52 / 56; or 1/4″, 1.3 mm (H00) at 10 / 12″ = 60 / 68.
- 542i XP: .325″ mini, 1.1 mm (SP21G) at 12 / 14 / 16″ = 51 / 59 / 64 DL, or .325″, 1.3 mm (SP33G) at 13 / 15″ = 56 / 64.
Husqvarna UK lists X-PRECISION SP21G as a .325″ mini, 1.1 mm chain. Oregon’s US part finder lists 80TXL (059 / 064) loops for the 540i XP.
Oregon Chains for Husqvarna
These are the chains Oregon’s own part finder lists for each saw (captured October 2026). Oregon’s finder does not list every model.
| Husqvarna Model(s) | Oregon chains listed | Drive links (Husqvarna manual) |
|---|---|---|
| 135 Mark II | UK: 91PX 040 / 045 / 052 / 056, 91P, M91VXL | 14″ 52, 16″ 56, 18″ 62 |
| 235 | US: 90PX 045 / 052 / 056, R45 / R52 / R56 (Husqvarna’s 235/236/240 manual lists Oregon 91PX) | 3/8″: 14″ 52, 16″ 56, 18″ 62 |
| 445 II, 450 II, 455 Rancher II | UK: 95TXL 056–078, M95VPX 056 / 064 / 072, Q21BP. US (455, 460): 20BPX / 20LGX / 20LPX and 72- / 73-series 3/8″ loops | See the Rancher list above |
| 120i | US: 90PX052 / R52. UK: 25AP058E | 12″ 45 |
| 340i | UK: 91PX / 91P / 91VXL 040–056 | 12″ 45, 14″ 52, 16″ 56 |
| 540i XP | US: 80TXL 059 / 064 | .325″ mini: 51 / 59 / 64 |
Oregon’s listings do not always match Husqvarna’s manual (for example, Oregon’s US finder lists 1.1 mm 90PX loops for the 235, while Husqvarna’s manual lists 1.3 mm chain and Oregon 91PX). Go by the pitch and gauge stamped on your bar.
Aftermarket Chains (Non-Oregon)
Other brands sell chains in Husqvarna sizes. We have not tested them; check the pitch, gauge and drive-link count against your bar before buying.
Where to Buy Husqvarna Chains
Husqvarna OEM Chains
Available through Husqvarna dealers and online. Husqvarna UK lists its chains by type (for example X-CUT SP33G, S35G, C85 and H42) with the drive-link count for each bar length.
Oregon Chains
Browse Oregon chains on Amazon. Oregon’s UK finder lists 95TXL and M95VPX (.325″ .050″) loops for the 445 II, 450 II and 455 Rancher II; check the gauge on your bar first.
SPARES2GO and Budget Options
SPARES2GO chains on Amazon. We have not tested them; check the pitch, gauge and drive links.

Key Compatibility Rules
Rule 1: Pitch Must Match Exactly
Oregon says the chain pitch must match the drive sprocket and the bar nose sprocket, so a 3/8″ chain and a .325″ chain are not interchangeable.
Rule 2: Gauge Must Match Bar Specification
Oregon says the gauge (drive-link thickness) must match the bar groove. The 120i uses 1.1 mm (.043″) and the 340i 1.3 mm (.050″), even though both are 3/8″ mini.
Rule 3: Drive Link Count Depends on Bar Length
The drive-link count follows the bar. On Husqvarna .325″ bars, Husqvarna lists 66 DL at 16″, 72 at 18″ and 78 or 80 at 20″. Oregon notes that the count varies by bar maker, so count your old chain.
Rule 4: Measure Your Current Chain
If you’ve lost your manual, remove your current chain and look for stamped markings. You’ll see something like “.325 .050 72 DL”. These three specs are all you need to order a replacement.

Frequently Asked Questions
What chain does a Husqvarna 445 Rancher use?
Husqvarna’s manual lists .325″ chain in 1.3 mm (.050″) or 1.5 mm (.058″). On an 18″ bar it is 72 drive links (16″ = 66, 20″ = 78 or 80 by manual edition). Match the gauge stamped on your bar.
Can I use a .325″ chain on my Husqvarna 135?
No. Husqvarna’s manual lists only 3/8″ chain (H37, which Husqvarna UK calls 3/8″ mini) for the 135. Oregon says the chain pitch must match the drive sprocket and the bar nose sprocket.
What’s the difference between a 445 and 450 Rancher in terms of chains?
Husqvarna’s manuals list the same .325″ chains and drive-link counts for both: 13″ = 56, 15″ = 64, 16″ = 66, 18″ = 72, 20″ = 78 or 80. What differs is the bar fitted, so count your old chain or read the bar.
Are Husqvarna battery chains (540i XP) compatible with petrol Rancher chains?
Not usually. The 540i XP’s .325″ mini X-PRECISION chain is 1.1 mm, while Rancher .325″ chains are 1.3 or 1.5 mm, so the gauges do not match.
Can I use an Oregon chain on my Husqvarna 445 Rancher?
Yes, if pitch, gauge and drive links match. Oregon’s UK part finder lists 95TXL and M95VPX (.325″ .050″) loops for the 445.
How often should I replace my Husqvarna chain?
We have not tested chain life, and the sources we hold give no Husqvarna figure. Replace a chain that will not hold an edge or has damaged teeth; a dull or damaged chain is a safety hazard.
My Husqvarna chain keeps coming loose. Why?
A loose chain usually means the tension needs adjusting or the chain is worn. Husqvarna’s manual gives the tensioning method for your saw; Oregon’s guidance is to adjust tension only when the chain is cool and the engine is off.

How we compile this guide
We cross-reference compatibility details against manufacturer specifications where available, official tool manuals, and the physical standards that govern fitment (bore sizes, arbor diameters, voltage platforms, connector types). We prioritise primary sources over retailer listings, flag anything we can’t confirm, and re-verify the data on a regular cycle. Where we give a buying recommendation, we tell you the reasoning — not just the link. More on our method →
