Original Makita ball bearing — part no. 210028-2 (606ZZ). This is a precision, double‑shielded deep‑groove ball bearing made to Makita’s specification for use in rotating shafts and small gear/armature assemblies.
Key specifications: 606ZZ form factor with double metal shields; nominal internal diameter 6 mm, external diameter 17 mm and width 6 mm (6×17×6 mm). Hardened-steel races and shields help reduce contamination and extend service life in tool gearboxes and motors.
Why this part matters for a repair: it restores correct running clearance and reduces vibration/noise when fitted to the motor, cam or gearbox shafts that use a 606-type bearing. Replace a worn or noisy 606ZZ with this original Makita part to return the tool to its intended running characteristics.
Example Makita models this part is used in (representative list): HR2630 and other rotary/combination hammer assemblies where the 606ZZ is shown in the parts diagram; UC3520A and UC4020A chainsaws; HR2470 demolition/hammer models; and a range of compact drills and small circular saw/gearbox assemblies. Use the part number 210028-2 to confirm fit with your tool’s exploded view or parts list.
What you get: one original Makita 210028-2 (606ZZ) ball bearing, ready to press or fit into the bearing housing. If your tool has a 6 mm shaft/support and the same bearing bore/outer housing dimensions, this is the direct replacement to restore smooth rotation.
