37320 - ESAB Knurled Drive Roll 1/16 - 5/64 Inch for Flux Cored Wire

Optimized Wire Feeding for Heavy-Duty Applications

The ESAB 37320 Knurled Feed Roll is a critical component for industrial welding operations utilizing large diameter flux-cored or metal-cored wires. Designed with precision engineering, this drive roll features a specialized knurled surface texture that bites into the softer outer sheath of tubular wires. This mechanical grip ensures consistent wire feeding speeds without the need for excessive tension arm pressure, which can crush the wire and lead to feeding issues or liner clogging.

This specific roll is dual-grooved to support two common heavy-industrial wire diameters: 1/16 inch (1.6 mm) and 5/64 inch (2.0 mm). By simply reversing the roll, operators can switch between wire sizes, adding versatility to their equipment setup. It is manufactured from hardened steel to withstand the abrasive nature of welding wire and the rigors of continuous industrial use.

Compatibility and Performance

Engineered to fit a broad range of ESAB wire feeders, this roll is compatible with the MigMaster® series (250, 251, 300i), MobileMaster 2, and Aristo® feeders. Using the correct drive roll geometry is essential for maintaining arc stability. While V-groove rolls are suitable for solid wires, they often slip on tubular wires. This knurled option eliminates slippage, ensuring that the wire feed speed set at the machine matches the actual output at the contact tip, resulting in higher quality welds and reduced downtime.
