13735895 - ESAB Replacement Axle for Multimaster 250/300i

Technical Overview of the ESAB 13735895 Axle

The ESAB 13735895 is a specialized structural component designed for the undercarriage assembly of specific ESAB welding power sources. Specifically engineered for the Multimaster 250 (MM250) and Multimaster 300i (MM300i) series, this axle serves as the primary load-bearing shaft for the machine's mobility system. In industrial environments, the undercarriage of a welding machine is subjected to significant static and dynamic loads, particularly when the machine is equipped with a full cylinder of shielding gas and a heavy spool of wire. This axle is manufactured to precise tolerances to ensure it fits the chassis mounting points and wheel hubs without excessive play, which could otherwise lead to instability during transport.

Failure of the axle typically occurs due to impact damage—such as dropping the machine from a height or striking an obstacle while rolling—or fatigue over long-term use in rugged shop environments. A bent or sheared axle compromises the safety of the unit, potentially causing the machine to tip or making it impossible to maneuver safely. The 13735895 replacement part is fabricated from durable steel, selected for its shear strength and resistance to deformation. It is supplied as a single unit, ready for installation into the existing wheel assembly hardware of the compatible Multimaster units.

Maintenance personnel sourcing this part should verify the machine model number to ensure compatibility. This component is strictly an OEM replacement and maintains the original manufacturer's specifications for ground clearance and track width. Proper installation of this axle is critical for maintaining the center of gravity of the welding cart, thereby ensuring compliance with workplace safety standards regarding equipment stability. It is recommended to inspect the wheels and retaining hardware (such as cotter pins or retaining rings) during the replacement process, as these associated components often sustain wear simultaneously with axle damage.
