133493 - Miller 133493 External Retaining Ring .250 Shaft (2-Pack)

Genuine Miller 133493 External Retaining Ring (2-Pack)

The Miller 133493 is a genuine OEM external retaining ring designed specifically for Miller welding equipment. This C-style clip is engineered to fit shafts with a diameter of 0.250 inches (1/4 inch) and features a precise thickness of 0.025 inches. Retaining rings, also known as snap rings or circlips, are critical fasteners used to hold components or assemblies onto a shaft or in a housing/bore when installed in a groove. In the context of welding machines, these are often found in wire drive assemblies, securing gears, rollers, or pivots in place.

Using genuine Miller parts like the 133493 ensures that the metallurgical properties and dimensional tolerances match the original specifications of your machine. Generic hardware may not provide the same tension or corrosion resistance required for the harsh environments often found in industrial welding. This product is sold as a package of two, providing a spare for future maintenance or immediate replacement of multiple worn clips. The external design allows for installation using standard retaining ring pliers or, in some cases, a flat-head screwdriver, making field repairs straightforward.

Maintenance professionals understand that small hardware failures can lead to significant downtime. A missing or broken retaining ring can cause drive rolls to slip or internal components to become misaligned. Keeping a pack of these Miller 133493 rings in your maintenance kit ensures you are prepared for routine service or unexpected repairs. Whether you are servicing a Millermatic, Bobcat, or a dedicated wire feeder, verifying fitment through your machine's parts manual is recommended to ensure this 0.250-inch clip is the correct size for your specific model.
