National Precision Bearing

What National Precision Bearing does

National Precision Bearing (NPB) is a precision bearing distribution and value-added services company operating as a division of Mechatronics, Inc. since 1979, headquartered in Preston, Washington. The company distributes ball bearings, roller bearings, needle bearings, spherical plain bearings, bushings, slewing rings, miniature bearings, thin section bearings, and related motion components sourced from over 100 bearing manufacturers including NMB (MinebeaMitsumi), JTEKT/Koyo, RBC, NHBB, INA/FAG (Schaeffler Group), SKF, Timken, and Kamatics. NPB holds AS9100D, AS9120B, ISO 9001:2015, ISO 13485:2016, ITAR registration, DFARS compliance, FDA 21 CFR Part 820, and US Government CAGE Code 5V122, with CMMC Level 2 compliance in implementation toward late 2026.

NPB serves aerospace, military/defense, medical/dental, industrial, precision instruments, and semiconductor manufacturing customers through six regional sales offices covering the United States (East, West, Central), Canada, Latin America, Asia, Australia, and Europe. Value-added services include ISO Class 6 clean room re-lubrication, rework, and inspection with over 150 specialty lubricant options and capacity exceeding 200,000 pieces per month, OEM-level bearing analysis and failure testing, government and defense logistics supporting DoD/DLA procurement, MIL-spec packaging, kitting and assembly, and stocking programs (VMI, JIT, Kanban) under long-term fixed-price agreements. The company is described as one of the largest stocking distributors globally for aerospace bearings and bushings and one of the largest bearing and bushing suppliers to the U.S. Government for defense and weapon systems applications.

The business model combines product distribution revenue (one-time bearing sales priced by type, precision class, materials, certifications, and volume on a quote-based B2B model), value-added services revenue (clean room relubrication, bearing analysis, kitting, assembly, packaging), and managed services revenue (VMI/JIT stocking programs, long-term agreements). NPB is part of Mechatronics, Inc., alongside sister companies Silverthin Bearing (thin section and slewing ring bearings), MechConnect (cable assemblies and wire harnesses, formerly Vertical Contract Manufacturing), and Mechatronics Fans (cooling fans and blowers). The company does not appear to be publicly traded, and no venture or private equity backing is disclosed.

Broad incumbents

• RBC Bearings: RBC Bearings is a leading U.S. manufacturer of engineered precision bearings serving aerospace, defense, and industrial markets — and is also a key NPB supplier partner. Highly comparable in aerospace bearing product overlap (plain, ball, roller), end-customer base, and AS9100D certification posture, though RBC owns the manufacturing while NPB is primarily a distributor.
• SKF: SKF is the world's largest bearing manufacturer with broad aerospace, industrial, and defense coverage — and is one of NPB's 100+ supplier brands. Comparable as a source of the same bearing categories NPB distributes, and as a competitor for direct OEM contracts in aerospace and machine tool spindles.
• Timken: Timken is a major U.S. bearing and power transmission manufacturer with deep aerospace, defense, and industrial exposure — and is listed as one of NPB's supplier brands. Comparable in aerospace and heavy-industrial bearing categories where Timken sells direct and through authorized distributors like NPB.
• Applied Industrial Technologies: Applied Industrial Technologies is one of North America's largest industrial distributors with deep bearings, power transmission, and fluid power coverage. Comparable as a multi-brand bearing distributor serving aerospace, industrial, and OEM customers, though with a much broader industrial customer base than NPB's aerospace/defense focus.
• Schaeffler Group (INA/FAG): Schaeffler is a global Tier-1 bearing manufacturer whose INA/FAG brands are major NPB distribution partners. Comparable across automotive, aerospace, and industrial bearing product lines, with NPB acting as an authorized distributor for Schaeffler's 40,000+ standard cataloged products.
• JTEKT (Koyo): JTEKT (owner of the Koyo brand) is a major Japanese bearing manufacturer with strong aerospace needle-bearing and roller-bearing lines — and is one of NPB's largest stocking distribution relationships. Comparable as an upstream supplier and direct competitor in needle bearings, track rollers, and aerospace-grade anti-friction bearings.

Direct peers

• BDI (Bearing Distributors Inc.): BDI is a major North American bearing and power transmission distributor carrying many of the same brands as NPB (SKF, Timken, INA/FAG, NTN). Comparable as a direct competitor in industrial bearing distribution, MRO, and value-added services for manufacturing customers.
• Aurora Bearing Company: Aurora Bearing is a U.S. manufacturer and distributor of rod ends, spherical plain bearings, and bushings — categories that closely overlap NPB's product portfolio. Comparable in aerospace rod-end and spherical bearing supply and in serving defense OEMs with AS9100-certified product.
• Silverthin Bearing: Silverthin Bearing is a sister company within Mechatronics, Inc. that manufactures thin section and slewing ring bearings for industrial and defense applications. Comparable as a Mechatronics-family affiliate with shared aerospace/defense customers and overlapping bearing product categories.
