191167 - Miller Running Gear Axle Assembly with Retaining Rings - 0.750 Inch Diameter

Precision Engineered Mobility for Industrial Welding Equipment

The Miller Electric 191167 Axle is a critical structural component designed specifically for the running gear of heavy-duty welding power sources. In the industrial environment, the mobility of welding equipment is paramount for operational efficiency. This axle serves as the foundational spine for the wheel assembly, bearing the significant static and dynamic loads imposed by industrial welders, wire feeders, and gas cylinders. Manufactured to precise tolerances, the shaft features a diameter of 0.750 inches, ensuring a tight, wobble-free fit with standard wheel bearings and hubs used in Miller's running gear lineup.

The length of the axle is machined to exactly 27.976 inches. This specific dimension is critical for maintaining the correct track width of the running gear, which directly influences the stability and center of gravity of the mobile unit. A deviation in length could compromise the structural integrity of the cart or lead to wheel misalignment, increasing wear on tires and bearings. The axle is constructed from high-grade steel, selected for its tensile strength and resistance to shear forces, ensuring it can withstand the rigors of transport across uneven shop floors, cables, and debris without bending or deforming.

Included with the axle are the necessary retaining rings (circlips). These fasteners are essential for lateral retention, preventing the wheels from migrating outward during movement. The grooves for these rings are precision-cut into the axle ends, ensuring a secure seat that resists vibration and shock. By utilizing this genuine OEM part, maintenance personnel ensure that the replacement meets the original engineering specifications of the equipment, preserving the safety and reliability of the welding setup. This component is an exact replacement for the original manufacturing part, facilitating a straightforward repair process that restores full functionality to the running gear system.

For MRO specialists and equipment technicians, sourcing genuine Miller parts like the 191167 axle guarantees compatibility and performance. It eliminates the guesswork associated with generic bar stock or universal axles, which often require cutting, drilling, or machining to fit. This ready-to-install solution reduces maintenance turnaround time, allowing valuable welding assets to return to production service with minimal delay.
