21162 - ESAB Serrated Drive Roll 5/64-3/32 Inch

Precision Wire Feeding for Heavy Industry

The ESAB 21162 Drive Roll is a critical component for industrial wire feeding systems, specifically engineered to handle large diameter welding wires ranging from 5/64-inch to 3/32-inch. Manufactured by ESAB, a leader in welding technology, this drive roll features a serrated profile designed to bite into the surface of the wire, providing positive traction that smooth drive rolls cannot achieve. This is particularly essential when working with flux-cored or metal-cored wires, where the tubular construction requires a firm grip to push the wire through long liners without crushing the delicate outer shell.

In high-volume manufacturing and heavy fabrication environments, wire feeding issues can lead to costly downtime and weld defects. The ESAB 21162 minimizes these risks by ensuring a constant, uninterrupted flow of filler metal to the contact tip. The hardened steel construction ensures durability even under the high-torque conditions required to feed heavy wires. Whether you are welding structural steel, heavy equipment, or shipbuilding components, relying on genuine ESAB parts ensures compatibility and performance maintenance for your wire feeder equipment.

Proper maintenance of your wire feeding system includes regularly inspecting drive rolls for wear. A worn serrated roll will lose its ability to grip the wire effectively, leading to erratic feeding. Replacing your old rolls with the ESAB 21162 restores the mechanical efficiency of your feeder, allowing your welding operators to focus on the puddle rather than troubleshooting equipment issues.
