48H352 - Walter 48-H-352 Replacement Motor Housing for Big Buff III & Line-Mate III

Technical Overview of the Walter 48-H-352 Motor Housing

The Walter 48-H-352 Motor Housing is a critical OEM replacement component designed specifically for the Walter Surface Technologies line of finishing tools, including the renowned Big Buff III and Line-Mate III. In industrial environments, power tools are subjected to rigorous use, thermal cycling, and mechanical stress. The motor housing serves as the primary structural chassis for the tool's stator and armature assembly, while simultaneously acting as the interface between the operator and the machine. This part is engineered to exact factory specifications to ensure seamless integration with existing internal components.

Manufactured from a high-grade, impact-resistant composite polymer, this housing is designed to withstand the harsh conditions typical of metalworking and fabrication shops. It features precise internal molding that secures the field coil and supports the brush holders in their correct orientation. Crucially, the housing design incorporates specific ventilation grilles and channels that direct cooling air over the motor windings. Using a damaged or non-OEM housing can disrupt this airflow, leading to premature thermal failure of the motor. Furthermore, the material provides necessary electrical insulation, protecting the operator from potential shock hazards associated with internal wiring faults.

Replacing a compromised housing is essential not only for the longevity of the tool but also for operator safety and comfort. Cracks or fractures in the housing can lead to misalignment of the bearing supports, causing excessive vibration and noise. By installing the genuine 48-H-352 housing, maintenance personnel ensure that the tool retains its original ergonomic profile, vibration dampening characteristics, and safety certifications. This component is supplied as the bare housing shell; hardware and internal electronics must be transferred from the original unit or purchased separately.
