JINFFR 18" Chainsaw Chain 5-Pack .325" Pitch .050" Gauge 72-Link — Hardened Steel, Chrome-Plated Semi-Chisel

These are five replacement 18-inch saw chains from JINFFR with a .325" pitch, .050" gauge and 72 drive links, engineered to fit many Husqvarna, Echo, Makita, Poulan and other popular chainsaw models.

If you need a ready supply of accurate-fit replacement chains for an 18" guide bar, this 5-pack gives you multiple spare chains built from hardened steel with chrome plating for corrosion resistance and sharpened semi-chisel cutters for smooth cutting. The chains match the common .325" pitch and .050" gauge and include 72 drive links — confirm those numbers on your saw's bar stamp or manual before ordering. JINFFR supplies aftermarket chains designed for broad compatibility across handheld and homeowner-class saws.

How do I confirm these chains will fit my saw?

Fit requires four matching parameters: bar length (18"), chain pitch (.325"), gauge (.050"), and the drive link count (72). Verify the numbers stamped on the side of your guide bar or in the owner's manual; if they match, the chain will correctly seat in the bar and sprocket.

• Bar length: 18 inches
• Pitch: .325"
• Gauge: .050"
• Drive links: 72

What performance and material features does the chain offer?

JINFFR chains are manufactured from high-hardness steel with chrome plating on cutting surfaces to resist corrosion and retain sharpness. The semi-chisel cutters provide efficient cutting with lower maintenance needs, while the low-kickback profile helps reduce reactive force during typical homeowner tasks.

• High-hardness German-style steel construction
• Chrome-plated cutters for wear and rust resistance
• Semi-chisel design for smooth, reliable cutting
• Engineered for low kickback behavior in common operating conditions

Which saw models and brands are compatible with these chains?

This 5-pack is specified to fit a wide range of gasoline chainsaws from Husqvarna, Echo, Makita, Poulan, Jonsered, McCulloch, Homelite, Remington, Ryobi, John Deere and others, especially many homeowner 40–60cc class models that use an 18" bar. Compatibility lists from aftermarket sellers are extensive; always cross-check your saw’s pitch, gauge and drive link count.

• Common Husqvarna models: 440, 445, 450, 545 and similar
• Echo and Makita homeowner chainsaws with 18" bars
• Poulan, Jonsered, McCulloch, Homelite, Remington, Ryobi and John Deere models noted for 18" chains
• Also fits various Craftsman, Efco and Partner models with matching specs

How should I install and maintain these replacement chains?

Installation is the same as any bar-and-chain swap: loosen the side cover, remove the old chain and bar, fit the new chain on the sprocket and along the bar groove, then tension according to the manufacturer’s instructions. Keep the chain lubricated, sharpen cutters as needed, and inspect for wear or damaged drive links to extend service life.

• Tension chain so drive links sit in bar groove without sag
• Use proper bar and chain oil for continuous lubrication
• Sharpen or replace chains before cutters become rounded
• Regularly check for damaged links, cracks or excessive stretch

Who is this for: This JINFFR 5-pack is aimed at homeowners, landscapers and small property owners who use 18" chainsaws and want spare chains on hand for frequent cutting, storm cleanup, or routine maintenance. If your saw lists .325" pitch, .050" gauge and 72 drive links, these chains provide a cost-effective way to keep a worksite running without interruptions.
