Luoyang– Where China‘s Bearing Industry Heartland Meets Global Precision Standards
In the landscape of global bearing manufacturing, few names carry the weight of history and technical accumulation as Luoyang—China’s undisputed bearing industry heartland. For over seven decades, this ancient capital has been the cradle of China‘s bearing industry, home to a unique combination of resources known as the “four uniques”: LYC Bearing Corporation, Luoyang Bearing Research Institute, Henan University of Science and Technology’s bearing program, and China Machinery Tenth Design Institute. This ecosystem has cultivated generations of engineering talent and established a complete industrial chain unmatched in the country.
It is on this fertile ground that Luoyang Ouna Bearing Co., Ltd. was founded in 2014. Located at No. 76 Airport Road, Luoyang Airport Industrial Cluster, Ouna Bearing has grown into a high-tech enterprise dedicated to the R&D, design, manufacturing and sales of super high-precision bearings. Our product portfolio includes thin-walled crossed roller bearings, high-precision ORT series rotary table bearings, precision four-point contact ball slewing bearings, high-precision thrust cylindrical roller bearings, and precision hoop type guide rails.
What sets Ouna Bearing apart? Our ability to deliver P5, P4 and P2 precision grades across an outer diameter range from φ20mm to φ2500mm—meeting the micron-level accuracy requirements of the world‘s most demanding equipment manufacturers. Our crossed roller bearings, including ORA, ORB, ORE, ORU, ORAU, ORBH, OSX, OXSU, OXU, ORBS series, and crossed tapered roller bearings JXR and XR series, are trusted by customers in high-precision CNC rotary tables, five-axis machining centers, industrial robots, DD motors, medical equipment and more.
As of 2025, the global cross roller bearings market was valued at US$592 million, with high-precision bearings accounting for over 54% of adoption—driven primarily by robotics (nearly 42% of demand) and machine tools (approximately 36%). With our products already reaching markets across Europe, America and Southeast Asia, Ouna Bearing is positioned to be your trusted partner in precision motion.
