MPB Corporation

MPB Corporation, a subsidiary of The Timken Company headquartered in Lebanon, New Hampshire, manufactures precision ball and roller bearings for aerospace and defense applications and operates as a prime contractor to the Defense Logistics Agency Aviation and other Department of Defense components (97% of awards), with minimal subcontractor exposure (3%). The company competes full-and-open on all contracts with no set-aside designations across its portfolio.

MPB Corporation's customer concentration is extreme and focused entirely on defense logistics. The top five customers account for 84% of recent awards by count, with the Defense Logistics Agency Aviation anchoring the portfolio at 1,659 awards worth $223.1 million combined potential value—representing overwhelming concentration in a single customer and procurement channel. The Defense Logistics Agency (non-Aviation) accounts for 620 awards at $21.1 million, followed distantly by the Department of the Army (159 awards, $13.6 million), the Department of the Navy Naval Supply Systems Command (90 awards, $7.4 million), and the Army Materiel Command Aviation and Missile Life Cycle Management Command (66 awards, $5 million). DLA Aviation alone represents 53% of combined potential value across the entire portfolio. This concentration reflects MPB's role as a specialized supplier of standard and specialty bearing components—cylindrical roller, ball annular, ball thrust, aircraft roller, and duplex bearings—to military aircraft platforms and ground vehicle systems under long-term standing relationships rather than competitive broad-based federal selling.

MPB Corporation holds ten active single-award Indefinite Delivery Contracts with DLA Aviation, ranging in ceiling value from $250,000 to $9.6 million and performance periods extending through 2030. These IDCs serve as the backbone of its federal footprint. Recent IDV awards include a $9.6 million cylindrical roller bearing contract (February 27, 2025), a $3.4 million aircraft roller bearing contract (June 6, 2024), a $1.28 million roller cylindrical bearing contract (November 26, 2025), and multiple smaller $250K–$1.2M vehicles for annular ball, aircraft roller, and specialty bearing types. Task order activity under these IDCs is consistent and steady—the $9.6 million vehicle alone has received seventeen delivery orders totaling approximately $1 million in initial demand since February 2025. Representative recent prime delivery orders include a $185.3 million aircraft roller bearing order (May 16, 2025), a $169.5 million annular ball bearing order (August 20, 2024), and a $154.5 million cylindrical roller bearing delivery order (August 21, 2024)—each issued on firm fixed-price terms against these standing vehicles. MPB also holds a $250,000 single-award IDC with the Ogden Air Logistics Complex for B-2 ball bearing procurement and a smaller $4.9 million Air Force contract for J85 engine roller bearing support. All prime awards carry no set-aside designations.

Activity has grown from 45 awards in 2022 to a peak of 131 in 2024, with recent moderation to 111 in 2025 and 18 awards year-to-date through mid-June 2026. Fifty-nine awards face ultimate completion within the next twenty-four months with combined potential value of $6.3 million—a moderate recompete exposure relative to the $421.5 million total portfolio, reflecting the stability of long-term IDV relationships rather than time-bounded task orders. Obligated spend stands at $265.7 million (63% of potential value), indicating a mature, invoiced revenue base.

MPB Corporation's subcontractor footprint is concentrated on rotary-wing military aircraft programs. The company subcontracts bearing components and assemblies to Bell Boeing Joint Project Office for the V-22 Osprey (frequent awards in 2024–2025), to Bell Textron Inc. for the H-1 series (AH-1W, UH-1Y, AH-1Z) and the Future Vertical Lift (FLRAA) program, and to The Boeing Company for AH-64 Apache advanced procurement and performance-based logistics. Representative sub-awards include multiple 2025 bearing deliveries for V-22 Production Lot 22 long lead-time items and H-1 SIEPU (Single Engine Improved Utility) time critical parts upgrades. This teaming pattern reflects MPB's role as a specialized component supplier embedded in major military aircraft sustainment and production programs rather than as a systems integrator or platform prime.

MPB Corporation's capability framing is bounded by its bearing manufacturing specialization. The portfolio is dominated by NAICS 332991 (Ball and Roller Bearing Manufacturing) work across 2,015 awards, with auxiliary exposure to Aircraft Engine and Engine Parts Manufacturing (134 awards) and Other Aircraft Parts and Auxiliary Equipment Manufacturing (113 awards), reflecting bearing applications in engine mounts and drivetrain systems. By PSC code, Bearings Antifriction Unmounted work accounts for 2,929 of 3,144 awards, with marginal exposure to mounted bearings (33 awards) and plain bearings (26 awards). Bearing types span cylindrical roller, annular ball, thrust ball, ball airframe, duplex, and specialty mast-rated bearings for vertical-lift platforms. Performance occurs primarily at facilities in Lebanon, New Hampshire (primary) and Rutherfordton, North Carolina (secondary), with subsidiary operations in Surry, New Hampshire noted in some IDV language.

The parent company, Timken U.S. Holdings LLC, holds no direct prime federal contracts; all federal work flows through MPB Corporation as the operating subsidiary. Bearing Inspection, Inc., a named subsidiary of MPB, appears in the corporate structure but is not referenced in award activity and likely serves internal quality assurance functions rather than external federal sales.
