Makita Genuine 515619-7 Armature Assembly 240v for Makita 9553NB, 9554NB, 9555NB Angle Grinder

The Makita 515619-7 Armature Assembly is a genuine OEM motor rotor designed to restore full performance to 240V Makita angle grinders, including the 9553NB, 9554NB, and 9555NB models.

Built around a laminated steel core with tightly wound copper coils, the armature delivers reliable power transfer from motor to gearbox. A precision-machined commutator ensures consistent speed and smooth commutation, helping to minimise sparking during operation.

An integrated 56 mm moulded cooling fan draws air through the motor housing during use, supporting thermal management under sustained load. This is particularly important for contractors running grinders continuously on site or in workshop environments.

This assembly is the correct replacement where the original armature has worn, burned out, or developed excessive noise and vibration. Being a genuine Makita part, it is manufactured to the same specifications as the original component, supporting accurate balance and fit within the motor housing.

Supplied dimensions allow confident identification before purchase, making it straightforward to confirm compatibility prior to stripping down the tool. Installation is a like-for-like replacement suitable for use with standard workshop tools.
