Original Makita 211278-2 — BALL BEARING 6203DDW: a genuine Makita deep‑groove ball bearing (6203DDW) manufactured to the same specification, with core dimensions 17 × 40 × 12 mm.
This double‑shielded 6203 variant is built for motor and spindle assemblies where smooth rotation and debris protection matter; it’s a direct‑fit, precision ground bearing that restores quiet, stable operation.
Compatible examples include a range of Makita angle grinders and saws — GA7021 / GA7020, GA7040, GA9020 / 9027 / 9029 grinders, LS1211, LS1212, LS1214 mitre/compound saws, 2704 table saw, and some drills such as DA4000LR (check your tool’s parts diagram for location 211278‑2).
If you need a reliable replacement, this original Makita bearing installs on a 17 mm shaft into a 40 mm housing and 12 mm width bore, making it an exact match where the 211278‑2 is specified — a small part that can make a big difference when sourcing parts for power tools.
