Chain bar guide Makita 191G52-5 50 cm length, 1.5 mm gauge, 3/8" pitch

Replacement chain bar guide Makita 191G52-5, 50 cm length, 1.5 mm gauge and 3/8" pitch is a spare guide bar intended for chainsaws that require a 50 cm bar and a narrow 1.5 mm chain gauge. The bar guides the cutting chain along the saw, maintains correct chain alignment and contributes to stable cutting performance in forestry and heavy-duty cutting tasks. It is compatible with chains and sprockets designed for a 3/8" pitch and fits Makita models and other chainsaws that accept this size and specification.

Advantages

The bar provides precise chain guidance and consistent tensioning thanks to its specified length and groove width, helping to reduce chain wobble and uneven wear. Constructed for durability, the guide bar supports continuous operation in demanding environments and simplifies replacement when compared with worn or damaged original bars. Its compatibility with 3/8" pitch chains and a 1.5 mm gauge makes it suitable for a wide range of professional cutting chains.

Suitable for

• Forestry and logging operations requiring a 50 cm bar
• Heavy-duty cutting of large trees and firewood
• Replacement parts for maintenance of Makita and compatible chainsaws
• Professional arborists and contractors using 3/8" pitch chains

Key specifications

• Bar length: 50 cm
• Chain gauge (groove width): 1.5 mm
• Chain pitch: 3/8"
• Function: guide bar for cutting chain alignment and support
• Intended use: professional and heavy-duty cutting applications

How to use

To replace an existing guide bar, first ensure the chainsaw is switched off and the spark plug or battery is disconnected. Release chain tension and remove the clutch cover or side panel according to the chainsaw manufacturer's procedure. Remove the worn bar and position the new 50 cm guide bar, aligning the bar nose with the sprocket and seating the chain in the bar groove. Refit the clutch cover, lightly tension the chain, then perform a final tension adjustment following the manufacturer's recommended chain tension. Check chain lubrication and perform a short test cut to verify proper alignment and smooth operation.

Usage recommendations

Use appropriate chain oil and maintain correct chain tension during operation. Inspect the bar groove and nose sprocket regularly for wear, clean the oil ports, and rotate or replace the bar if uneven wear appears. Match the bar with a correctly sized 3/8" pitch, 1.5 mm gauge chain and follow safety guidelines for heavy-duty cutting.
