48L360 - Walter Big 6 Grinder Replacement Armature 120V

Restore Precision Power with the Walter 48L360 Armature

The Walter 48L360 Armature Complete is a critical replacement component designed to restore the functionality and performance of Walter Surface Technologies' heavy-duty angle grinders. Specifically engineered for the Big 6 series (models 30-A 265 and 30-A 267), this OEM part ensures that your industrial power tools operate at the high standards required for professional metalworking applications. The armature serves as the rotating heart of the electric motor, converting electrical energy into the mechanical torque needed for grinding, cutting, and finishing tasks.

Over time, the armature in a high-performance grinder can succumb to wear and tear due to extreme heat, vibration, and carbon brush friction. Symptoms of a failing armature often include excessive sparking at the commutator, a burning smell, intermittent power loss, or the tool failing to start altogether. Replacing a damaged unit with the 48L360 ensures that the magnetic field interactions within the motor are optimized, returning the tool to its original RPM and torque specifications. This assembly typically comes complete with the cooling fan and commutator pressed onto the shaft, simplifying the repair process for maintenance technicians.

Using genuine Walter replacement parts is essential for maintaining the safety and longevity of your equipment. Aftermarket or generic armatures may not match the precise balancing or winding quality of the original, leading to increased vibration and premature bearing failure. The 48L360 is wound with high-grade copper and insulated to withstand the thermal stresses of continuous industrial use. Whether you are repairing a tool for a fabrication shop, a welding station, or a maintenance department, this armature provides the reliability professionals demand.

Technical Compatibility

This 120V armature is strictly compatible with specific Walter Big 6 grinder models. Before purchasing, please verify your tool's model number on the nameplate. Proper installation involves disassembling the grinder housing, removing the carbon brushes to prevent damage, and carefully seating the new armature into the field case. It is also recommended to inspect and potentially replace the carbon brushes and bearings simultaneously to ensure a complete refurbishment of the motor system.
