OVERVIEW

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.

FAQ

It acts as a locking element that fits into a slot (keyway) on both the shaft and the rotating hub (like a wheel or gear) to transmit torque and prevent them from rotating independently.

Yes, this is a genuine OEM replacement part manufactured by Walter Surface Technologies, ensuring exact specifications for their equipment.

Signs include the accessory (wheel/disc) slipping while the motor spins, unusual rattling noises from the drive assembly, or visible deformation/shearing of the key upon inspection.

It is made from high-strength industrial steel designed to resist shear forces and wear.

While possible, it is not recommended. OEM keys are sized to specific tolerances. A loose key can damage the shaft keyway, leading to expensive repairs, while an oversized key won't fit.

This part fits specific Walter power tools. Please refer to the exploded view diagram or parts manual of your specific Walter tool (e.g., Line-Mate, Big Buff) to confirm the part number 48J723.

Disassemble the hub or flange from the shaft, remove the old key (and any debris), place the new key into the shaft keyway, and reassemble the components. Ensure a snug fit.
