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

Precision Wire Feeding for Automatic Systems

The ESAB Bogie No.4 (Part Number 0366902883) is a critical component designed for the wire feed mechanisms of ESAB's heavy-duty automatic welding heads, specifically the A2 and A6 series. In automated welding processes such as Submerged Arc Welding (SAW) or high-deposition MIG/MAG, the consistency of wire delivery is paramount to achieving defect-free welds. This bogie assembly is engineered to maintain constant pressure and traction on the welding consumable, ensuring that the wire feed speed (WFS) remains synchronized with the welding parameters set by the process controller.

This specific unit features a 2.4mm (3/32 inch) VK-Groove configuration. The "VK" designation typically indicates a V-style groove with knurling or specific geometry optimized for gripping flux-cored wires or solid wires in heavy-duty applications where slippage must be eliminated without deforming the wire cross-section. The assembly includes high-quality ball bearings ("BB"), which reduce rotational friction and wear on the motor drive train, extending the service life of the entire feed unit. By using genuine ESAB replacement parts, operators ensure that the mechanical tolerances of the feed system are maintained, preventing issues such as wire shaving, bird-nesting, or irregular arc length caused by feed fluctuations.

Installation of the Bogie No.4 is straightforward, designed to fit directly into the modular architecture of ESAB's automatic heads. It is an essential spare for maintenance teams managing automated welding lines, ensuring minimal downtime during routine service intervals. The robust construction is built to withstand the thermal and mechanical stresses common in industrial environments, from shipyards to pressure vessel fabrication shops.
