48J723 - Walter Replacement Parallel Key for Power Tools

Genuine Walter Replacement Parallel Key

The Walter 48J723 Parallel Key is a critical mechanical component designed for the maintenance and repair of Walter Surface Technologies power tools. As a genuine OEM part, this parallel key is manufactured to precise tolerances, ensuring a snug and secure fit within the mating keyways of the tool's shaft and the mounted hub or accessory. Parallel keys are essential for transmitting torque from the motor to the working end of the tool, preventing rotation between the shaft and the driven component.

Constructed from high-quality, durable steel, this key is engineered to withstand the shear forces and vibrations typical of industrial grinding and finishing applications. Over time, machine keys can wear down, become deformed, or shear off completely as a sacrificial safety measure to protect the motor during jams. Replacing a compromised key with this exact-match component restores the structural integrity of the drive assembly, ensuring smooth operation and safety. It is recommended to check your specific tool's parts diagram to confirm compatibility with part number 48J723.

Technical Application

This component is typically used in the drive train of Walter electric power tools, such as grinders, polishers, or finishing tools (e.g., Line-Mate series), to lock drive rollers or flanges to the output spindle.
