W4017211 - Lincoln Electric .045-1/16 V-Knurled Drive Roll Kit (Set of 2)

Optimized Wire Feeding for Tubular Consumables

The Lincoln Electric W4017211 Feed Roll Set is a critical component for industrial welding operations utilizing flux-cored (FCAW) or metal-cored (MCAW) welding processes. Designed with precision engineering, these drive rolls feature a V-Knurled (VK) groove geometry specifically tailored to grip the softer, tubular structure of cored wires without compromising their integrity. Unlike smooth V-groove rolls used for solid wire, the knurled teeth on these rolls bite into the wire surface, providing positive traction that eliminates slippage even under lower tension settings. This mechanical advantage is essential for maintaining consistent wire feed speeds, which directly correlates to arc stability and deposition rates in high-volume production environments.

This kit includes a set of two rolls, accommodating wire diameters of .045 inches (1.2 mm) and 1/16 inches (1.6 mm). The dual-size capability or specific sizing (depending on feeder configuration) allows for versatility in shop floor setups. Manufactured from hardened steel, these rolls are built to withstand the abrasive nature of knurled feeding and the rigors of continuous industrial use. Proper maintenance of the wire feeding system, including the timely replacement of worn drive rolls, is paramount to preventing downtime caused by bird-nesting or erratic feeding. The W4017211 set ensures that your Lincoln Electric wire feeder operates at peak efficiency, delivering the reliability required for structural steel fabrication, heavy equipment manufacturing, and shipbuilding applications.

Integrating genuine Lincoln Electric parts like the W4017211 into your maintenance schedule guarantees compatibility and performance. These rolls are engineered to fit specific Lincoln wire feeder models, ensuring correct alignment with the wire guide and liner system. By reducing the crushing force required to move the wire, these knurled rolls also extend the life of the liner and contact tip by minimizing wire shaving generation. For procurement managers and maintenance supervisors, stocking these drive rolls ensures that production lines running heavy cored wires remain operational with minimal interruption.
