What JTEKT makes

JTEKT Corporation supplies four major product families to the global automotive industry: steering systems, bearings, driveline components, and machine tools. Within the automotive supply chain, it is best known for electric power steering and bearings, both of which it sells directly to vehicle manufacturers worldwide.

The steering portfolio spans every major architecture in current production. JTEKT's own materials state that it developed the world's first electric power steering (EPS) system for mass production in 1988, and the company describes itself as holding the top EPS market share since then. Current production lines cover column-type, pinion-type, dual-pinion, and rack direct-drive EPS, as well as hydraulic power steering variants and electronically controlled variable-gear-ratio systems. Intermediate shafts, steering columns, and power steering pumps round out the unit and component side. The steer-by-wire program -- branded Syncusteer since May 2026 -- builds on a linkless architecture in which the steering unit and road-wheel actuator carry no mechanical connection. A high-heat-resistant lithium-ion capacitor called Libuddy provides the backup power supply mandated for fail-safe operation.

Bearings are sold under the KOYO brand, which traces to Koyo Seiko's founding in 1921. The range covers ball, tapered roller, cylindrical roller, needle, and hub-unit bearings for automotive and industrial use. A June 2026 development announcement describes grease-lubricated ceramic ball bearings rated to 30,000 rpm, designed for electric vehicle eAxle applications.

Driveline products include propeller shafts, all-wheel-drive systems, electromagnetic clutches, and eAxle differentials. The machine tools division -- sold under the TOYODA and WELE MECHATRONICS brands -- produces cylindrical grinders, machining centers, and CNC controllers for manufacturing customers. Production part approvals and advanced product quality planning are described as standard procedure across the product range.

Per the Berylls by AlixPartners Top-100 Automotive Suppliers study for FY2025, JTEKT reported automotive-sector revenue of approximately €8.0 billion, an operating margin of 3.5%, and revenue growth of 5.7% year over year.

Ownership and history

JTEKT Corporation was incorporated in January 2006 through the merger of Koyo Seiko and Toyoda Machine Works -- two companies with separate but complementary roots inside the Toyota ecosystem. Koyo Seiko began bearing production in Osaka in 1921 and grew into one of Japan's principal bearing manufacturers. Toyoda Machine Works was a machine-tool pioneer with pre-war origins. The merger combined Koyo Seiko's bearings platform with Toyoda Machine Works' steering and machine-tool businesses under a single legal entity.

The company is headquartered at 1-1 Asahi-machi, Kariya, Aichi Prefecture, Japan -- the same city as Toyota Motor Corporation's main operations. Toyota Motor Corporation is JTEKT's largest shareholder, holding 24.3% of issued shares as of September 2024, per JTEKT's IR materials. Toyota Industries Corporation holds an additional 1.2%. Per company filings cited in investor coverage, approximately 42.7% of JTEKT's consolidated net sales are to the Toyota Group. The company describes itself as maintaining strategic independence in serving other automakers.

Global manufacturing covers North America (nine or more plants across Tennessee, South Carolina, and Georgia; one facility in Canada; one in Mexico), Europe (bearing and sales operations in the UK, Netherlands, Germany, France, Romania, and Czech Republic), Asia (Japan, China, India, Thailand, Philippines, Indonesia, Malaysia, Korea), South America (Brazil, Argentina), and Africa (Morocco). European automotive manufacturing subsidiaries were transferred to LEO III.-VV25-B SAS, a vehicle advised by DUBAG Investment Advisory of Munich, effective July 31, 2026, completing the divestiture ahead of schedule.

Certifications and quality

JTEKT's automotive product lines operate within customer quality frameworks that require IATF 16949 compliance as a precondition for supply. The company describes APQP and PPAP as standard procedure across its manufacturing operations. Published anti-counterfeiting measures introduced in April 2026 include hologram-equipped QR codes on packaging for genuine parts, supporting product authentication across the aftermarket.

Known customers

Internal sourcing databases show JTEKT's US subsidiaries -- JTEKT Bearings North America (Vonore, Tennessee) and JTEKT Toyoda Americas (Arlington Heights, Illinois) -- receiving inbound shipments from the Japanese parent and from JTEKT Bearings Romania as recently as September 16, 2026, with a combined record of more than 10,000 US ocean-freight shipments.
