Pioneer Serves the Naval and Marine Markets

Since World War II, Pioneer has continually been a qualified supplier to the U.S. Navy and Department of Defense. Our bearings can be found on nuclear submarines, aircraft carriers, frigates and destroyers.

Our quality system is in compliance with the U.S. Government’s
MIL-I-45208A standards as well as Michell’s, but we make sure that all our work is up to clients’ standards and expectations.

Pioneer products help various industries keep operations up and running smoothly:


Pioneer is the senior bearing repair licensee of Siemens Energy. We have virtually all Westinghouse and Siemens bearing drawings and specifications on hand, with revisions, and the legal right to use them in the performance of repair services we sell direct to end users.

We also have 17 years of experience repairing and manufacturing (often on short lead times to meet the requirements of power plant outage schedules) ABB, Alstom, GEC and Brown Boveri fluid film bearings. As a result, Pioneer is as familiar with Alstom bearing designs, material specifications and quality assurance requirements as anyone in North America.

Our comprehensive alliance with Michell Bearings of Newcastle, U.K. (a member of the Rolls-Royce Group) allows Michell and Pioneer to share their respective technologies, engineering services and associated technical support under cross trade secret license agreements.
