ILJIN Motion & Control GmbH

What ILJIN Motion & Control GmbH does

ILJIN Motion & Control GmbH is a privately held German limited company headquartered in Frankfurt am Main, operating commercially as ILJIN Bearing Art. The company is the European commercial and R&D vehicle of the South Korea-founded ILJIN Group (established 1973 as a forging company), and focuses on precision motion control components for the automation industry. Its core technology is the strain wave gear (harmonic drive), developed since 2018, which provides zero-backlash, high-torsional-stiffness, single-stage gear reduction in compact and lightweight form factors. The product portfolio spans strain wave gear sets and units (Cup, Hat, and Short Cup styles with solid or hollow cam options), fully enclosed strain wave gearboxes, high-rigidity crossed roller bearings (30mm-250mm OD range) with optional anti-corrosion coating, and rotary actuators.

The company sells directly to enterprise customers in automotive, robotics, mobility, humanoids/animatronics, medical, logistics, and agricultural automation through regional offices in Frankfurt (Europe R&D), Seoul (Asia R&D), Novi, Michigan (Americas sales and warehousing), and Yeongju, South Korea (high-volume production with capacity exceeding 100 million items per year group-wide). Revenue is generated primarily through B2B hardware sales on a quote-based, multi-year contract model with no publicly disclosed pricing. The company emphasizes a full-service offering — design, testing, small batch manufacturing, and customization — combined with drop-in replacement compatibility for class-leading strain wave gear brands.

ILJIN's established automotive OEM credentials are demonstrated by nine consecutive General Motors Supplier of the Year awards (2015-2023), four Fiat Chrysler Automobiles Supplier of the Year awards (2004, 2011, 2014, 2017), and a Daimler Innovation Award (2017). The company's strategic focus has shifted toward the higher-growth automation, collaborative robotics, and humanoid robotics markets, where its precision motion components address the need for compact, torque-dense, and repeatable motion control in robotic joints and actuators.
