48H501 - Walter Line-Mate III Motor Brush Holder Assembly

Technical Overview of the Walter 48H501 Brush Frame Assembly

The Walter 48H501 Brush Frame Assembly is a critical internal component designed specifically for the maintenance and repair of the Walter Line-Mate III (Model 30-A 268) linear finishing tool. As a genuine OEM (Original Equipment Manufacturer) part, this assembly is engineered to meet the exact specifications of the original tool, ensuring seamless integration with the motor housing and armature system. The brush frame serves as the structural foundation for the carbon brushes, holding them in precise alignment against the motor's commutator. This alignment is vital for efficient electrical transmission and smooth motor operation.

Over time, the heat and vibration generated during heavy-duty industrial sanding and finishing applications can cause wear or thermal degradation to the brush frame. A compromised frame can lead to loose brushes, arcing, intermittent power loss, or even catastrophic damage to the motor's armature. Replacing a damaged frame with the 48H501 restores the structural integrity required for the brushes to slide freely yet remain firmly in contact with the commutator. The assembly is constructed from high-quality, heat-resistant materials capable of withstanding the thermal loads typical of continuous industrial use.

Technicians and maintenance personnel rely on genuine Walter parts to maintain the safety and performance certifications of their equipment. Using the 48H501 ensures that the spring tension and brush positioning remain within factory tolerances, preventing premature wear of replacement carbon brushes. This part is an essential stock item for facilities utilizing Line-Mate III tools for metal finishing, ensuring that downtime is minimized and tool reliability is maintained at peak levels.

When servicing the Line-Mate III, it is recommended to inspect the brush frame whenever changing carbon brushes. If signs of melting, cracking, or excessive play are observed, immediate replacement with this assembly is necessary to protect the tool's motor. This component represents Walter's commitment to long-lasting, serviceable industrial power tools.
