48M748 - Walter 120V Replacement Armature for Big Buff III and Line-Mate III

Restore Factory Performance with the Walter 48M748 Armature

The Walter 48M748 Armature Complete (120V) is a critical replacement component designed to breathe new life into your high-performance Walter surface finishing tools. As the rotating heart of the electric motor, the armature is responsible for converting electrical energy into mechanical motion. Over time, heavy industrial use can lead to wear on the commutator or windings, resulting in power loss, excessive sparking, or complete motor failure. This genuine OEM part ensures that your equipment returns to the precise operational standards set by the manufacturer.

Engineered specifically for 120V systems, this armature assembly comes complete with the necessary windings, commutator, and cooling fan pre-installed. It is precision-balanced to minimize vibration, which is crucial for finishing tasks where surface consistency is paramount. Using non-OEM parts in high-torque tools like the Big Buff III or Line-Mate III can lead to premature bearing failure or overheating; the 48M748 guarantees a perfect fit and thermal profile.

Compatibility and Installation

This part is primarily designed for Walter's renowned finishing tools, specifically the Big Buff III and Line-Mate III. When replacing an armature, it is also recommended to inspect the carbon brushes and bearings, as these components often wear simultaneously. Installing this complete armature assembly restores the torque and RPMs required for heavy-duty grinding, polishing, and graining applications.
