0349312062 - ESAB Wire Feeder Pressure Roller Bearing

Restore Smooth Wire Feeding

Is your MIG welder sputtering or feeding wire unevenly? Before you blame the liner or the contact tip, check your pressure rolls. The ESAB 0349312062 Bearing/Pressure Roll is the genuine replacement part you need to get your wire feeder running smoothly again. The pressure roll (often called the idler or top roll) is responsible for sandwiching the wire against the drive roll. Over time, the bearings inside can dry out, seize up, or become gritty, preventing the roll from spinning freely. When this happens, the wire drags, slips, or gets crushed, leading to frustrating "birdnesting" and poor weld quality.

Swapping out a damaged pressure roll is one of the easiest and most effective maintenance tasks you can perform on your welder. This ESAB 0349312062 unit is built to the exact specs of your machine, ensuring a perfect fit in the tension arm assembly. A fresh bearing allows the roll to spin effortlessly, providing consistent traction on the wire without requiring you to crank down the tension knob excessively—which can deform flux-cored or aluminum wires. By restoring proper feeding mechanics, you'll notice an immediate improvement in arc stability and start performance.

Don't let a small, inexpensive part cause downtime in your shop. If you hear squeaking from your feeder or notice the wire hesitating, it's time to inspect your pressure rolls. Keeping a spare ESAB 0349312062 on hand ensures you can fix feeding issues immediately and get back to laying beads. This part is designed for durability and long life, giving you peace of mind that your equipment is ready to work when you are.
