48H440 - Walter Line-Mate Replacement Joint Sleeve

Precision Replacement for Linear Finishing Tools

The Walter 48H440 Joint Sleeve is a critical replacement component designed specifically for the maintenance and repair of Walter Surface Technologies' linear finishing systems, most notably the Line-Mate III. As a genuine OEM part, this sleeve is engineered to the exact dimensional tolerances required to maintain the structural integrity and drive efficiency of the power tool. In high-performance finishing environments, the mechanical connection between the drive motor and the abrasive mounting system is paramount for achieving consistent finishes and ensuring operator safety.

Constructed from high-grade industrial materials, the Joint Sleeve withstands the torque and rotational forces generated during heavy-duty sanding, polishing, and graining operations. Over time, mechanical wear on internal coupling components can lead to increased vibration, slippage, or misalignment of the abrasive drum. Replacing worn sleeves with the 48H440 restores the tool's original balance and power transfer capabilities, ensuring that the Line-Mate continues to deliver the superior satin and matte finishes it is known for.

Maintenance personnel and tool technicians will appreciate the direct-fit nature of this component, which eliminates the need for modification during installation. By utilizing genuine Walter parts, facilities ensure compliance with equipment warranty standards and prolong the operational lifespan of their capital equipment. This part is an essential stock item for workshops relying on Walter linear finishers for stainless steel and metal fabrication tasks.
