Chain for chainsaw Makita 73LPX 50 cm pitch 3/8" gauge 1.5 mm (MPN 191H52-1)

Replacement cutting chain Makita 73LPX for a 50 cm guide bar offers a direct-fit option for compatible chainsaws. The chain uses a 3/8" pitch and a 1.5 mm gauge, designed to match bars and sprockets specified for this medium-pitch configuration. Supplied as a single chain, it is intended to restore cutting capability on saws that require these dimensions and to maintain consistent cutting performance for general woodcutting tasks.

Advantages

The Makita 73LPX chain provides consistent tooth geometry and manufacturing tolerances typical of chains designed for professional and semi-professional use. Its 3/8" pitch balances cutting speed and smoothness, while the 1.5 mm gauge helps reduce vibration and wear on the guide bar when used with compatible equipment. Being a direct replacement for 50 cm bars, it simplifies maintenance and avoids the need for reconfiguration of the saw’s drive system.

Suitable for

• Felling medium to large trees with a 50 cm guide bar
• General firewood cutting and limb removal
• Property and land maintenance requiring a medium-pitch chain
• Replacement chain for compatible Makita and other chainsaws accepting 3/8" pitch and 1.5 mm gauge

When it may not be suitable

This chain is not suitable for guide bars or saws that require a different pitch or gauge; using the wrong dimensions can cause poor fit, accelerated wear, or unsafe operation. It may also be less appropriate for precision pruning or arborist work where a smaller pitch and narrower gauge are preferred for finer cuts and reduced weight.

Key specifications

• Designed for 50 cm (approximately 20") guide bar lengths
• Chain pitch: 3/8" (medium pitch)
• Chain gauge (thickness): 1.5 mm
• Type: replacement cutting chain, single unit

How to use

Fit the chain to the saw following the manufacturer’s instructions for bar and chain installation: ensure the chain direction matches the drive sprocket, seat it on the guide bar groove, and tension it to the correct specification. Check lubrication and chain oil supply before use, and inspect the chain for damage or missing teeth. After fitting, run the saw at low speed to confirm proper seating and recheck tension. Regular sharpening, cleaning, and lubrication will maintain cutting performance and extend chain life.

What to consider before purchase

• Confirm your chainsaw’s required pitch (3/8") and gauge (1.5 mm) and that your guide bar length is 50 cm.
• Verify compatibility with your saw’s sprocket and bar groove design.
• Consider whether you need a full complement chain versus a special low-vibration or low-kickback design for your application.

Usage recommendations

Use appropriate personal protective equipment, maintain recommended chain tension and lubrication, and perform routine sharpening with the correct file size for 3/8" pitch chains to ensure safe and effective cutting.
