From our very beginning in 1920, first-rate, quality manufacturing has been a hallmark of Pioneer’s accomplishments and the primary way we grew our business. With our California heritage and experience as our rich legacy (as described in our history), today we perform all manufacturing and in-house repair work in our modern purpose-built plant we built and opened in 1990. In recent years, we added a third manufacturing bay and expanded our engineering offices. The plant is 34,000 square feet (3,159 sq. meters) under roof, entirely devoted to fluid film bearings and seals.
We manufacture and repair fluid film bearings ranging in size from outside diameters of a few inches to over 100 inches (254 centimeters), though the majority has bore sizes over 14”. With good overhead crane capacity, we efficiently handle bearings weighing up to 10,000 pounds (over 4.5 metric tons) for the largest turbines and generators at work in fossil, nuclear and hydroelectric power plant
For more than half a century, we’ve manufactured bearings for OEMs and end users of large land-based and offshore rotating equipment and the U.S. Navy.
Over the past 15 years an increasing percentage of production is devoted to our own designs, including our Fluid Pivot® JC and JS tilting pad journal bearings.
