Founded in 2011, NBR Motion is a precision bearing component specialist manufacturing steel balls, tapered rollers, ceramic balls, and raceways—the critical internal elements of finished bearings.
As of 2025, product-mix by revenue is tapered rollers 61%, steel balls 30%, and raceways 9%; by end market, automotive (ICE and xEV) accounts for approximately 65%, with robotics and wind energy comprising the remaining 35%.
The company operates as a Tier-2 supplier, delivering components to Tier-1 bearing module makers such as Schaeffler, SKF, NSK, and Nabtesco, which in turn supply finished bearings to automakers, industrial equipment producers, and robotics companies.
Its defining technical moat is the capability to manufacture G5-SP (Special Precision) grade steel balls—the highest precision class under ISO standards, tolerating just 0.1–0.2 micrometers of deviation—making it one of only three companies worldwide capable of doing so, alongside Japan's NSK and Tsubaki.
In tapered rollers, NBR Motion holds the rank of global third-largest dedicated producer (excluding integrated bearing manufacturers) and is the sole domestic manufacturer in Korea.
Competitively, the primary rivals are entrenched Japanese precision bearing firms, and NBR Motion differentiates through localization-driven cost and lead-time advantages and a vertical integration strategy for raw materials.
The company has made upfront capital investments totaling KRW 62.3 billion to build the largest domestic production footprint at its Miryang and Changwon facilities.
Ceramic ball technology development was completed in 2024 and raw-material in-sourcing—targeting a 40% cost advantage over Japanese competitors—is on track for 2026.
The global bearing components market is estimated at approximately KRW 200 trillion as of 2025 and is projected to grow at a roughly 7% CAGR, underpinned by rising demand for high-precision components across EVs, robotics, and aerospace.
