Makita 345464-4 — Labyrinth ring (metal). Genuine Makita replacement dust/dirt ring that seats in the bearing box around the spindle to block abrasive dust and debris from reaching the spindle bearing. Made of metal for durability and listed as the factory labyrinth ring used on Makita grinders and planers; sold as a single replacement piece.
Fit Makita Models : 9553HN / 9553NB / 9554NB , 9555NB , 9556NB , 9556PB , 9557NB, 9558NB , GA4030 / GA4034, GA4530 / GA4534, GA5020 / GA5034, BGA450, and some PC5000 / PC5001 planers. Use the part when the original ring is bent, worn, or missing to restore bearing protection and keep the tool running smoothly.
Installation notes: the ring fits into the bearing/gearbox area and is normally replaced when you service the spindle or bearing — removal of the wheel guard and a few fasteners is usually required and a screwdriver is commonly used during installation. Replace a damaged ring to prevent premature bearing failure from dust ingress.
Part number: 345464-4. Genuine Makita, direct replacement for the factory labyrinth / dust ring used on the models listed.
