MPB Corp

MPB Corp, operating as the Timken Super Precision Division and a subsidiary of The Timken Company through parent Timken U.S. Holdings LLC, manufactures high-precision ball bearings, duplex bearings, airframe bearings, and related precision mechanical components for the Department of Defense as a prime contractor on full-and-open, non-set-aside federal contracts. The company competes exclusively in unrestricted competition with no set-aside designations across its federal footprint.

MPB Corp's federal business concentrates heavily on bearing supply to Defense Logistics Agency Aviation through multiple single-award indefinite delivery contracts and numerous firm fixed-price purchase orders and delivery orders. The vendor holds four active IDCs with DLA Aviation: a $1,997,510.68 ceiling contract awarded October 22, 2025, extending through October 2030; a $732,680.04 ceiling contract for duplex ball bearings awarded September 25, 2024, through September 2029; a $250,000 ceiling contract for annular ball bearings awarded February 18, 2022, through February 2027; and a $250,000 ceiling contract for annular ball bearings awarded September 9, 2021, through September 2026. Recent representative prime awards include a $101,340.00 delivery order from DLA Aviation on April 10, 2026, for annular ball bearings (ultimate completion June 11, 2027); a $125,921.04 purchase order on September 24, 2025, for annular ball bearings (completion October 27, 2026); and a $106,220.40 purchase order on April 29, 2024, for airframe ball bearings (completion October 13, 2025). A $539,213.35 firm fixed-price purchase order from the Defense Contract Management Agency on May 4, 2023, procured gyro subassemblies, representing work beyond standard bearing supply.

Customer concentration is acute: DLA Aviation alone accounts for 969 awards (covering 83% of the award count) with $43 million in combined potential value. The Department of the Navy Naval Supply Systems Command contributes 84 awards valued at $20.2 million combined. The top five customer agencies account for 92% of combined potential value, with DLA Aviation and Navy programs anchoring the portfolio. The vendor serves 28 distinct federal agencies across the prime portfolio, but activity outside DLA Aviation and Navy is minimal by dollar magnitude.

Activity has grown substantially year over year: 14 awards in 2022, 28 in 2023, 46 in 2024, 33 in 2025, and 4 awards to date in 2026. The recompete cliff shows 20 awards with ultimate completion in the next twenty-four months, carrying combined potential value of $802 thousand—modest exposure given the portfolio's total $71.2 million combined potential value. Real obligated dollars ($138.1 million) exceed combined potential value by 194%, indicating consistent order flow and invoicing against the IDC vehicles.

MPB Corp subcontracts bearing and bearing-adjacent components to major defense primes. Named prime contractors include Lockheed Martin Corporation (for F-35 aircraft long-lead bearing items, M-TADS/PNVS target acquisition systems, and JASSM missile programs); Raytheon Company (Stinger missile production, Patriot firing unit programs, and RAM GMRP MK 44 missile bearings); The Boeing Company (common aerospace commodities); Bell Boeing Joint Project Office (common aerospace commodities); DRS Network & Imaging Systems LLC (periscope head assemblies and missile spare parts); Honeywell International Inc. (ball bearing deliveries); L3Harris Technologies (GEOXO Imager instrument bearings); Northrop Grumman Systems Corporation (NEOPP satellites); and Spartan Education LLC (Apache M-TADS/PNVS systems). The subcontract footprint is broad across air and missile defense platforms.

MPB Corp also received a $21.4 million cooperative agreement from the Office of the Secretary of Defense under the Defense Production Act Title III Program, awarded March 3, 2023, for sustainment of critical production capability and capacity for high-precision ball bearings, extending through November 30, 2027. This grant underscores federal commitment to maintaining domestic bearing manufacturing capacity for national defense.

Place of performance centers on Surry, New Hampshire, with distributed fulfillment from facilities in Keene, New Hampshire (headquarters), Taunton, Massachusetts, and Dedham, Massachusetts. The company's NAICS concentration is Ball and Roller Bearing Manufacturing (1,117 awards), with secondary work in guided missile components (90 awards) and aircraft parts (50 awards). PSC coding reflects antifriction bearing supply (1,734 awards) as the dominant procurement category. MPB Corp competes in full-and-open competition across all prime contract vehicles and holds no set-aside certifications in its federal footprint.
