Canadian owned and operated
The Lincoln Electric Ball Bushing Assembly (9SM18947-1) is a critical replacement component designed exclusively for the Lincoln LF-74 wire feeder series. In the demanding world of industrial welding, the internal mechanics of a wire feeder are subjected to constant stress, vibration, and repetitive motion. Over time, the bushings that support the drive shafts or pressure arm mechanisms can wear down, leading to excessive play ('slop') in the system. This mechanical looseness often manifests as erratic wire feeding, slipping drive rolls, or inconsistent wire alignment.
This genuine OEM part ensures that your equipment operates exactly as the engineers at Lincoln Electric intended. Unlike aftermarket generic parts that may have slight dimensional variances, this ball bushing assembly is manufactured to precise tolerances to fit the LF-74 housing perfectly. The assembly features high-quality materials designed to minimize friction and withstand the heat and dust typical of a shop environment. By replacing worn bushings with this authentic Lincoln part, you are effectively extending the service life of your feeder and protecting the more expensive drive motor and gear components from unnecessary strain.
Maintenance professionals understand that proactive replacement of wear items is key to avoiding unplanned downtime. If you have noticed increased noise from your feeder or if the drive rolls seem to struggle despite correct tension settings, a worn bushing assembly could be the culprit. Installing the 9SM18947-1 restores the tight mechanical tolerances required for smooth, reliable wire delivery, ensuring your production line keeps moving efficiently.
