Makita 224301-4 Spare Part - OUTER FLANGE 42 5903R

Original Makita outer flange — part no. 224301-4 — a heavy‑duty Ø42 mm steel blade flange that clamps the blade to the spindle and works with the inner flange and M8 blade bolt to keep the blade centered and secure.

Designed to replace a worn or damaged outer flange on Makita 235 mm circular saws, this genuine Makita part restores accurate blade runout and reliable clamping pressure for safer, cleaner cuts; it’s the correct flange for models such as the 5903R and N5900B (also shown in parts lists for related 590x series saws).

Simple to fit with basic tools — the flange mates to the spindle assembly (inner flange 224302/224303 series and M8 retaining bolt) and is a direct, drop‑in replacement so you can get back to work without modifying other components. This is a commonly replaced item among power tool parts when a saw blade begins to wobble or slip.
