0366902883 - ESAB Bogie No.4 Feed Roller Assembly 2.4mm VK-Groove

Keep Your ESAB Tractor Running Smoothly

If you are running an ESAB A2 or A6 tractor for long seams, you know that the wire feeder is the heart of the operation. When your feed rolls or bogies get worn out, you start seeing wire slippage, sputtering arcs, and inconsistent bead profiles. That's when it's time to swap in a fresh ESAB Bogie No.4 (0366902883). This isn't just a roller; it's the full bogie assembly designed to get your heavy-duty automation back on track.

This particular bogie is set up for 2.4mm (3/32") wire, a standard size for serious structural and tank work. It features a VK-Groove, which gives you that extra bite on the wire. Whether you are pushing solid wire or cored wire, that texture ensures the drive rolls grab on tight and push the wire through the liner and contact tip without slipping, even if there is a bit of resistance. The "BB" in the spec stands for Ball Bearings—meaning this thing spins freely and handles the heavy down-pressure required for feeding thick wires without grinding itself to dust.

Don't let a worn-out feed assembly ruin a perfect sub-arc run. Replacing the bogie is a quick maintenance fix that pays for itself immediately in weld quality. This genuine ESAB part drops right into your existing feed unit, restoring factory-level performance. It is built tough to handle the heat, dust, and continuous duty cycles of industrial fabrication. Keep a spare on the shelf so you aren't caught waiting for parts in the middle of a shift.
