142317 - Miller Wire Feeder Gearbox Grease #00

Technical Overview of Miller Mori-White #00 Grease

The Miller 142317 Mori-White #00 Grease is a specialized semi-fluid lubricant engineered for the maintenance of industrial welding equipment. Classified under NLGI Grade #00, this grease possesses a consistency intermediate between a fluid oil and a soft grease. This specific rheology is critical for enclosed gearboxes found in wire feed systems, where the lubricant must flow readily to coat moving gears while possessing enough body to prevent leakage and maintain a protective film under load.

Formulated as a white grease, likely utilizing a lithium or similar thickener system, it offers excellent mechanical stability and resistance to oxidation. The white pigmentation serves a functional purpose in maintenance environments, allowing technicians to easily identify the presence of contaminants or wear particles within the lubricant during inspection. Unlike stiffer greases (NLGI #2) which may channel and starve gears of lubrication, the semi-fluid nature of Mori-White #00 ensures continuous replenishment of the contact zones within the drive assembly.

As a genuine Miller Electric OEM part, this grease meets the precise specifications required for the longevity of Miller wire feeders and drive motors. Using non-compliant lubricants with incorrect viscosity or additive packages can lead to increased gear wear, overheating, and premature failure of the drive system. This product is essential for preventative maintenance schedules (PM) to ensure equipment operates within factory parameters.
