Precision Engineered for Global Industries
Established in 1921, KOYO Bearings (a core brand of JTEKT Corporation) stands as Japan's third-largest bearing manufacturer and a global leader in motion control solutions. With over a century of innovation, KOYO integrates cutting-edge materials science, precision engineering, and IoT-enabled technologies to deliver bearings that excel in extreme conditions while reducing operational costs and energy consumption. Certified to ISO 9001/14001, KOYO operates R&D centers across Japan, the Americas, Europe, and China, serving 150+ countries with 48-hour OEM support367.
Core Technologies & Advantages:
Ultra-High Speed & Low Heat Generation: Patented HA-series spindle bearings (e.g., HA- with direct oil-air lubrication) enable 1.5× higher rotational speeds and 30% lower temperature rise versus conventional designs1.
Extended Service Life: Proprietary heat treatment and surface coatings (e.g., EXSEV series) enhance durability by up to 200% under heavy loads35.
Eco-Efficiency: Low-friction ceramic hybrid bearings (Si3N4 balls) reduce energy loss by 15-30%, certified ISO 1400136.
Smart Monitoring: X-Tracker® series with embedded sensors enable real-time load/temperature diagnostics for predictive maintenance3.
Global Applications:
Automotive (EV/Hybrid Systems, Wheel Hub Units), Aerospace (Landing Gear Bearings), Robotics, Machine Tools, Wind Turbines, Steel Mills, and Medical Equipment.
