Located in the historic California steel town of Pittsburg, Bishop-Wisecarver is part of the community's rich manufacturing and industrial history. The bustling 85,000-square-foot plant is a far cry from the humble Oakland machine shop where the company's founder Bud Wisecarver got his start in the 1950s.


The original plant was built on a defunct WWII military training base, Camp Stoneman. Bud's plant was part of a post-war industrial boom in the San Francisco Bay Area. Decades later, we're still a vital part of the local economy as a firmly established global manufacturer of linear guide wheel technologies.
