Description
Overview:
The Labyrinth Ring is a genuine Makita spare for angle grinders, designed to keep dust and debris away from critical moving parts. This durable metal ring forms part of the grinder's dust‐deflection system, helping to protect bearings and the gear housing for smoother running and a longer service life. Manufactured to Makita standards as OEM No. 345464-4 (MPN 345464-4), it fits a wide range of compact Makita grinders, including 9554NB and 9557PB. By maintaining a tight, non-contact labyrinth path, it reduces premature wear, supports consistent performance, and helps the tool operate reliably in harsh, dusty environments. Suitable for both trade and DIY users, it is an ideal maintenance replacement when refurbishing the nose section, bearings, or gear case.
