Makita 415300-9 — genuine Makita labyrinth (dust protection) ring designed to seal the motor/bearing area of Makita angle grinders and keep abrasive dust and debris out of the gearing and bearings.

The part is a molded labyrinth-style dust seal (commonly listed as d12×34), built to press into the housing around the spindle to extend bearing life and reduce premature wear.

Fits many Makita angle-grinder models in the 9540/9541/9542 and 9564/9565 families (examples: 9564CV, 9565PCV and related 9541/9565-series grinders and some SG1250/SG1251 units) — check your model's parts breakdown to confirm placement before installation.

Sold individually and easy to install as a press-fit replacement, this genuine Makita part makes a compact, cost-effective repair that restores proper sealing and helps your tool run cooler and last longer. Use Makita spare parts when replacing seals to keep original fit and function; this item is one of the common power tool parts technicians keep on hand for grinder repairs.
