Original Makita armature (rotor) 515208-8 — a direct-fit replacement rotor/commutator assembly for the motor in select Makita 220–240 V tools. This rotating core restores motor torque and smooth running when the original armature is worn, overheated, or producing excessive sparking.
Key specifications (metric):
- Total length: ≈ 188 mm.
- Shaft (tail) diameter / fit: 6 mm.
- Lamination (stack) diameter: ≈ 35 mm; stack length ≈ 55 mm.
- Commutator diameter: ≈ 24 mm. Distance between bearing centres ≈ 136 mm. Lower/upper bearing types commonly listed as 627 and 12 respectively.
- Cooling fan diameter (integral): ~58 mm; rated for 220–240 V mains.
Compatibility — fits (examples):
- Makita SG1250, SG1251 (wall chasers).
- Makita 9566 series angle grinders: 9566C, 9566CV, 9566CR, 9566CVR (and closely related 125 mm grinder variants).
Why choose the original Makita 515208-8:
- Restores factory motor geometry (rotor/commutator alignment) so the tool runs quietly and with correct brush contact.
- Built with factory windings and commutator for reliable electrical performance under load and correct mechanical fit in the motor housing.
Notes for fitment: this is the armature/rotor assembly (not bearings, brushes or the stator). Use the listed model numbers above to confirm compatibility with your machine’s spare-parts diagram or the reference on your old rotor before installation.
