Makita Genuine 518338-4 Armature Assembly 110v 9920/9903

The Makita Genuine 518338-4 Armature Assembly is an OEM replacement component designed to restore full electrical function to Makita 9903 and 9920 belt sanders operating on 110v power supplies.

The armature assembly sits at the heart of the motor, converting electrical energy into the mechanical energy that drives the sander. When this component fails or becomes worn, tool performance drops significantly — making a like-for-like genuine replacement the most reliable route to getting your equipment back to full working order.

As a genuine Makita part, the 518338-4 is manufactured to the same tolerances and specifications as the original component. This ensures compatibility with the 9903 and 9920 models and removes the risk of fitment issues or premature failure that can come with non-OEM alternatives.

This part is well suited to professional contractors, site maintenance teams, and tool repair specialists who need to minimise downtime and maintain the working condition of their belt sanders. Using a genuine OEM component also helps preserve the integrity and service life of the tool.
