Genuine Makita ball bearing 211256-2 (6203-series) — sealed on both sides — for smooth, low-friction rotation in motors and gear assemblies. Inner diameter 17 mm, outer diameter 40 mm and width 12 mm (17×40×12 mm), compatible with 6203LLB / 6203-2RS style bearings. This original Makita part is used in several grinders, saws and demolition hammers (example models: GA7911, HM1800 / HM1810, 9607B / 9609B and LS1030), so it’s a direct-fit replacement when a worn bearing is causing noise, vibration or loss of power.
