DatsenAAA 18" Chainsaw Bar & Chain Combo — .325" Pitch, .050" Gauge, 72 Drive Links, Factory-Sharpened

An 18-inch replacement chainsaw bar and .325" pitch, .050" gauge chain combo with 72 drive links engineered to fit a wide range of Husqvarna, Jonsered, Makita, Troy-Bilt and similar chainsaws.

This DatsenAAA bar and chain bundle is built for homeowners and pros who need a durable, low-maintenance cutting setup that drops into many popular two-stroke and modern gas chainsaw models. The set arrives ready to run with a factory-sharpened chain, chrome-plated cutters, hardened rivets and a bar designed for dependable oil distribution. It’s intended as a direct-fit replacement when your original 18" bar or worn chain has reached the end of its service life.

Which chainsaws will this 18" bar and chain work with?

This combo is compatible with numerous models from Husqvarna, Jonsered, Makita and Troy-Bilt listed by manufacturers and common aftermarket specifications. Fit depends on mounting style, nose sprocket type and expected pitch/gauge; confirm your saw uses 72 drive links with .325" pitch and .050" gauge before ordering.

• Husqvarna models: common 50–60 series and Rancher/XP lines noted in the product list.
• Jonsered and Makita saws that accept 72 links with .325" pitch.
• Troy-Bilt homeowner models listed (TB4620, TB4920, TB5018, TB5020, TB5518).
• Check your saw manual or remove the side cover to count drive links and confirm gauge.

How does the chain construction improve cutting and durability?

This chain uses Japanese chrome-plating and precision grinding to deliver longer initial sharpness and elevated wear resistance. Hardened, quenched rivets combined with German steel for the cutters improve toughness and reduce chain stretch, resulting in steadier tension and fewer interruptions for adjustments.

• Chrome-plated cutters resist abrasion and hold an edge longer.
• Heat-treated rivets and controlled punching minimize deformation.
• Flatness control in the bar and precision manufacturing reduce vibration and kickback tendencies.
• Factory-sharpened teeth make it ready for immediate use.

What maintenance and lubrication features are included?

The bar is designed to work with your chainsaw’s automatic oiling system, spreading oil to the chain and bar rails to lower friction and prolong component life. Regular chain tension checks and periodic sharpening remain necessary, but the combination of plating and heat treatments reduces how often intensive maintenance is required.

• Compatible with standard automatic oilers found on listed chainsaw models.
• Chrome plating and hardened rivets cut down on wear between oiling cycles.
• Keep the oil reservoir topped and verify the bar groove is clean for optimal lubrication.
• Inspect tension before each use and re-tension when cool for safety and performance.

How do I confirm fit and install safely?

Confirm your saw’s pitch (.325"), gauge (.050"), and the required drive link count (72) before purchasing. Installation follows standard bar-and-chain replacement steps: remove side cover, release tension, mount bar and loop chain over the sprocket, set initial tension, then torque hardware to manufacturer specs and recheck tension after a short break-in cut.

• Verify your saw model appears in the compatibility list or has matching specs.
• Use proper PPE and disconnect spark/plug before performing maintenance.
• Set slightly loose initial tension, then re-tighten after warming up under light load.
• Follow the saw maker’s torque and adjustment directions for safe installation.

This DatsenAAA 18" bar and chain combo is for homeowners, arborists and occasional pro users who need a robust, ready-to-run replacement that fits many popular consumer and professional chainsaws. It’s especially useful if you want longer edge life out of the box, improved wear resistance through chrome plating and heat-treated components, and a product that integrates with your saw’s automatic oiling system. Not intended for saws requiring different pitch, gauge or drive link counts—always confirm specs before purchase.
