ESAB 0558102457 Replacement Woodruff Key

Get Your Welder Back Up and Running

When your welding machine or wire feeder stops feeding wire smoothly, the problem isn't always the motor—sometimes it's a small, inexpensive part that has sheared off to protect the rest of the system. The ESAB Crescent Woodruff Key (0558102457) is the genuine replacement part you need to lock your drive rolls or gears back onto their shafts and get back to welding. If you are experiencing slippage where the motor turns but the wire doesn't move, a sheared or missing key is a common culprit.

This "half-moon" shaped key is designed to fit perfectly into the slot on your ESAB machine's shaft. Because it is an official ESAB part, you don't have to worry about filing it down to fit or having it rattle loose due to poor sizing. It drops right into the curved slot on the shaft and locks the pulley or gear in place, ensuring that every bit of power from your motor goes into feeding your wire. It is a simple fix that can save you from buying expensive replacement motors or drive assemblies.

Keeping a few of these keys in your maintenance kit is a smart move for any shop running ESAB equipment. They are small and easy to lose during disassembly for cleaning or repair. Having the correct 0558102457 key on hand means the difference between a quick 5-minute repair and a machine that sits down for days waiting for parts. This key is built from durable steel to handle the torque of industrial welding environments, giving you the reliability you expect from the ESAB brand.

Don't let a ten-cent problem cause a thousand-dollar delay. Ensure your wire feeder's drive system is solid and secure with this authentic ESAB replacement key. It installs easily—just tap it into the shaft slot until it sits level, slide your gear or drive roll over it, and you are ready to weld.
