0153321001 - ESAB Spool Hub Lower Disc Replacement

Genuine ESAB Lower Disc for Wire Feeder Maintenance

The ESAB 0153321001 Lower Disc is a specialized replacement component designed for the spool hub assembly of select ESAB wire feeders. In industrial welding environments, the consistency of wire delivery is paramount to achieving high-quality welds. This lower disc plays a crucial role in the braking mechanism of the wire spool holder, providing the necessary friction interface or structural support to control the rotation of heavy wire spools.

Over time, mechanical parts within the wire feed system experience wear due to the constant rotation and friction involved in the welding process. A worn or damaged lower disc can lead to erratic spool braking, causing the wire to coast or "overrun" when the welding trigger is released. This often results in bird-nesting or tangling of the wire, which causes downtime and wasted consumables. By replacing this component with a genuine ESAB part, you ensure that the spool hub operates within factory specifications.

This part is manufactured to ESAB's exacting standards, ensuring a perfect fit with compatible wire feed units. It is constructed from durable materials capable of withstanding the mechanical stress of daily industrial use. Whether you are performing preventative maintenance or repairing a malfunctioning feeder, the 0153321001 Lower Disc is essential for restoring the reliability of your welding equipment.

Key Benefits:

• Restores proper spool braking function.
