0366966882 - ESAB 1.2-2.0mm Knurled Drive Roll for Flux-Cored Wire

Precision Engineered Knurled Drive Roll

Optimize your welding operations with the ESAB Feed Roller NR3 1.2-2.0 VK, specifically manufactured for the demands of flux-cored arc welding (FCAW) and metal-cored arc welding (MCAW). Identified by part number 0366966882, this drive roll is a critical replacement part for maintaining the efficiency of your ESAB wire feeding system. The "VK" designation indicates a V-Knurled groove profile, which is the industry standard for feeding tubular wires.

One of the primary causes of wire feeding downtime is slippage. When using cored wires, increasing tension on a standard smooth roller often results in crushing the wire, causing it to drag in the liner or jam at the contact tip. The ESAB knurled roller solves this by using mechanical grip rather than friction alone. The textured groove grabs the wire securely, allowing for lower tension settings on the drive motor. This reduces wear on the feeder motor and extends the life of the liner while preventing the dreaded "bird-nesting" of wire at the feeder inlet.

This specific roller is rated for wire sizes between 1.2mm and 2.0mm, covering the most common diameters used in heavy industrial welding. The precision-machined groove ensures that the wire remains centered, providing accurate alignment with the outlet guide. Made from high-grade hardened steel, the roller resists the abrasive wear typically caused by the drawing of wire, maintaining its dimensions and grip profile even in harsh shop environments.

Regular inspection and replacement of drive rolls are necessary maintenance procedures for any professional welding setup. If you notice metal shavings accumulating in the feeder or experience inconsistent wire speed, it may be time to replace your rollers. Choose the ESAB 0366966882 for a direct-fit solution that restores your machine's performance to factory specifications.
