Original Makita ball bearing 627DDW (part no. 210027-4) — a direct replacement bearing used in Makita angle grinders and rotary sanders to restore smooth spindle rotation and reduce vibration.
Sealed deep‑groove design with metric dimensions 7 × 22 × 7 mm (bore × outer Ø × width), made to the 627 series specification for high‑speed motor applications.
Fits a range of Makita grinders and related tools; commonly referenced in exploded parts diagrams as position 016 and listed for models such as the 9562, 9564 and 9565 series, as well as GA/BO/SG series tools (for example GA5040, BO6040, SG1250).
Sold as a single, original Makita replacement bearing that press‑fits onto the spindle or rotor shaft — an essential Makita spare parts item when a noisy or rough‑running tool needs a quick, reliable repair.
Small and simple to fit but critical to safe, vibration‑free performance; this part is one of the common parts for power tools used in grinders, sanders and polishers, so confirm the part number against your tool’s parts diagram before installation.
