48C115 - Walter 110V Replacement Armature for Mini-Grinder

Restore Your Walter Grinder's Performance

The Walter 48C115 Armature is a critical OEM replacement component designed to revitalize your Walter Surface Technologies electric power tools. Operating at standard 110V/120V, this armature serves as the rotating heart of your grinder's motor, converting electrical energy into the high-torque mechanical rotation required for demanding industrial applications. Over time, armatures can suffer from wear due to heat, vibration, or brush friction, leading to loss of power, excessive sparking, or complete motor failure.

Engineered to Walter's precise manufacturing standards, this replacement part ensures a seamless fit within the motor housing of compatible Mini-Grinder models. It features high-grade copper windings insulated to withstand the thermal stresses of heavy-duty grinding, along with a precision-machined commutator that ensures smooth electrical contact with the carbon brushes. By replacing a damaged armature with this genuine part, you can eliminate vibration issues and restore the tool's RPM to factory specifications.

Maintenance professionals understand that repairing a high-quality tool is often more cost-effective than replacing it. The 48C115 allows you to extend the service life of your equipment significantly. Installation should be performed by qualified personnel to ensure proper seating of the bearings and alignment of the brushes. Trust in genuine Walter parts to maintain the safety and durability you expect from your industrial tools.
