0366966881 - ESAB Knurled Drive Roll 1.4mm-2.4mm for Flux Cored Wire

Precision Wire Feeding for Heavy Fabrication

The ESAB 0366966881 Feed Roll is a specialized component designed to optimize the performance of ESAB wire feeding systems. Engineered specifically for the 1.4mm to 2.4mm wire diameter range, this roll is an essential accessory for welders utilizing flux-cored (FCAW) or metal-cored (MCAW) welding processes. The roll features a knurled groove design, which provides the necessary traction to push softer, tubular wires through the liner and gun cable without crushing the wire's cross-section. This is critical for maintaining the structural integrity of the wire and ensuring the flux core remains undisturbed until it reaches the arc.

Manufactured from high-grade hardened steel, this feed roll is built to withstand the rigors of industrial environments. The precise machining ensures that the roll fits perfectly onto the drive shaft of compatible ESAB feeders, reducing runout and vibration. By maintaining a consistent grip on the wire, the 0366966881 helps prevent common feeding issues such as slippage, bird-nesting, and erratic wire speeds, which can lead to porosity and poor weld quality. Whether you are welding structural steel, heavy equipment, or pipe, relying on genuine ESAB drive rolls ensures your equipment operates at peak efficiency.

This specific roll covers a versatile range of wire sizes, from approximately 0.052 inches up to 3/32 inches, making it a flexible solution for shops that switch between different heavy-duty wire gauges. Proper installation and tensioning are key to maximizing the life of the roll and the quality of the weld. When paired with the correct pressure arm and guide tubes, this knurled feed roll delivers the reliability professional welders demand.
