167633 - Miller 167633 Nylon Shoulder Washer .612 ID x 1.060 OD

Precision Miller Replacement Hardware

The Miller 167633 Washer is a specialized shoulder washer designed to meet the rigorous standards of industrial welding equipment. Manufactured from high-grade nylon, this component serves a critical role in the assembly and maintenance of Miller power sources and wire feeders. Nylon is chosen for this application due to its excellent electrical insulating properties, resistance to corrosion, and ability to withstand the thermal fluctuations often present inside welding machinery. As an OEM (Original Equipment Manufacturer) part, it guarantees a level of fit and finish that aftermarket alternatives cannot match, ensuring that the tolerances required for your machine's safe operation are strictly maintained.

Technically, this washer features a complex geometry tailored for specific mounting points. It has an Inner Diameter (ID) of 0.612 inches, allowing it to fit precisely over designated shafts or bolts without excessive play. The main body has an Outer Diameter (OD) of 1.060 inches with a thickness of 0.062 inches, providing a broad bearing surface to distribute load and prevent damage to mating components. Additionally, the "shoulder" portion of the washer has a diameter of 0.787 inches and a matching thickness step of 0.062 inches. This stepped design is essential for centering components within an assembly or isolating a bolt from the chassis to prevent electrical grounding. Using the correct shoulder washer is vital for preventing short circuits and mechanical looseness that could lead to equipment failure.

When servicing industrial equipment, every component matters. The Miller 167633 is not just a spacer; it is an engineered solution for component isolation and alignment. Whether you are rebuilding a vintage Miller welder or performing routine maintenance on a modern unit, verifying the dimensions and material specifications is key. This nylon shoulder washer offers the resilience and dielectric strength necessary to keep your welding operations running smoothly and safely.
