080842 - Miller 080842 Neoprene Step Bushing .160 ID x .500 OD (5-Pack)

Precision Engineered OEM Replacement Component

The Miller 080842 Bushing is a specialized step bushing manufactured from high-grade neoprene, designed specifically for compatibility with select Miller welding power sources and wire feeders. As an essential component in the assembly and maintenance of industrial welding equipment, this bushing serves a critical role in isolating components, dampening vibration, or acting as a precise spacer within the machine's internal architecture. The choice of neoprene (polychloroprene) as the manufacturing material is significant; it offers excellent chemical stability and maintains flexibility over a wide temperature range, which is crucial in the harsh thermal environments often found inside welding equipment.

Technically, this bushing features a stepped design with an internal diameter (ID) of 0.160 inches, an outer diameter (OD) of 0.500 inches, and a total height of 0.250 inches. These precise tolerances ensure a snug fit, preventing mechanical play that could lead to wear or misalignment of connected parts. The "step" profile indicates it is likely used to seat into a panel or bracket, providing a shoulder for positive retention. Using genuine Miller OEM parts like the 080842 ensures that the dimensional accuracy matches the original engineering specifications of the machine, preserving the integrity of the assembly.

In MRO (Maintenance, Repair, and Operations) contexts, replacing worn or degraded bushings is a preventative measure that extends the service life of capital equipment. Neoprene bushings can degrade over time due to exposure to ozone, heat, and mechanical stress. Signs of failure might include increased vibration, noise, or loose components. This 5-pack configuration allows maintenance technicians to replace multiple wear points simultaneously or keep stock on hand for immediate repairs, minimizing downtime. Whether used for electrical insulation or mechanical spacing, this component meets the rigorous quality standards expected of Miller Electric replacement parts.

Installation of these bushings should be performed according to the specific service manual for the Miller equipment in question. The elasticity of the neoprene material aids in installation, allowing for a secure press-fit in many applications without the need for additional adhesives or retaining hardware, depending on the specific assembly design. By maintaining the correct spacing and isolation of internal components, the 080842 bushing contributes to the overall reliability and safety of the welding system.
