Guide Bar NAC 18" (45 cm) 62/3/8" 1.3 mm Single Rivet

Guide Bar NAC 18" (45 cm) 62/3/8" 1.3 mm Single Rivet is a replacement guide bar designed for use with compatible NAC chainsaws and equivalent models. With a length of 45 cm and a 1.3 mm gauge, this bar guides the cutting chain, maintains correct alignment and supports proper chain tension during cutting tasks. The single rivet mounting hole fits saws that accept single-rivet bars and helps secure the bar to the chainsaw body for general cutting, pruning and timber work.

Advantages

The guide bar is constructed to provide a stable channel for the cutting chain and to resist bending under typical cutting loads. Its 1.3 mm gauge ensures compatibility with chains that match this thickness, enabling smooth chain movement and reliable cutting performance. The single rivet configuration simplifies installation on compatible machines and reduces the number of attachment points. The bar’s 45 cm length offers extended reach for mid-size felling and bucking tasks while remaining manageable for pruning and on-site timber processing.

Suitable for

• Mid-size tree felling and bucking where a 45 cm bar is preferred
• Pruning and limb removal on medium-diameter branches
• General timber cutting and firewood preparation
• Replacement of worn or damaged guide bars on compatible NAC and equivalent chainsaws

Key specifications

• Bar length: 18 inches (45 cm)
• Pitch specification: 62/3/8"
• Gauge (chain thickness): 1.3 mm
• Mounting: single rivet/mounting hole

How to use

Fit the guide bar following the chainsaw manufacturer’s instructions for your model: remove the side cover, release chain tension, position the bar on the studs, loop the chain over the sprocket and into the bar groove, then restore tension to the chain and replace the side cover. After installation, check chain tension, lubrication flow and guide bar alignment before operation. Inspect the bar rails and groove for even wear and ensure the oiling ports are unobstructed for proper chain lubrication during use.

Usage recommendations

Use chains compatible with a 1.3 mm gauge and the specified pitch to ensure safe operation. Maintain correct chain tension, sharpen the chain regularly, and use proper chain oiling. For best results, inspect the bar periodically for burrs, rail wear and groove damage; flip or replace the bar when wear is uneven. Follow all safety guidelines for chainsaw operation and wear appropriate personal protective equipment.
