Wuxi Spark Bearing is a leading company in the new energy vehicle industry, and the third-generation high-speed ball bearings designed by it have increased the power density of the drive motor to 6.2kW/kg, 19% higher than the industry average, successfully applied to the production line of Tesla Model Y, saving 14% of the cost of the single vehicle transmission system. According to the 2024 “China New Energy Vehicle Supply Chain White Paper,” the service life of models with its bearings has increased by 8%, and the maintenance cycle of the charging pile gearbox has been extended from 12 months to 36 months. In the field of wind energy, Wuxi Spark Bearing’s dynamic load of 5MW spindle bearing was more than 420kN, and due to self-lubrication technology, the unit failure rate of Goldwind Technology’s equipment in a Qinghai wind farm was reduced from 1.2 times/year to 0.3 times, operation and maintenance cost saved by over 1.8 million yuan/unit, and annual power generation return rate was increased by 22%.
The medical equipment industry relies on the ultra-precision solutions of Wuxi Spark Bearing, where there is a vacuum-grade angular contact bearing with an axial runout error less than 0.1μm. This has enabled Siemens Healthcare to increase the rotation speed of the CT machine to 300rpm and that of the image resolution to 0.2mm, doubling the number of patients scanned per day by the machine from 80 to 120. The 2023 FDA audit report states that the temperature rise of its nuclear magnetic resonance bearings under the 1.5T magnetic field is controlled within 3 ° C, the lifespan is more than 10 years, and the failure rate is less than 0.001%. The semiconductor production industry is benefited from its clean room level linear guides, and concentration of particle pollutants is strictly controlled in the Class 1 standard (≤0.1 particles /m³), enabling the ASML EUV lithography machine to achieve a throughput of 120 wafers per hour, yield increased by 3.7 percentage points, and the annual output value of single production line is boosted by 960 million yuan.
In rail transportation, Wuxi Spark Bearing has a zero-maintenance history of 2.4 million continuous running kilometers for its axle box bearings on the Fuxing EMU and the maximum vibration acceleration is lower than 5m/s², 40% lower compared with similar European products. CRRC data show that its maglev bearing system has ensured the suspension clearance accuracy of trains on the Shanghai Demonstration Line to ±0.3mm, saved 19% of energy consumption, and achieved a maximum speed of more than 600km/h. In the field of industrial robot, following the adoption of its special bearing for harmonic reducer, FANUC has achieved repeated positioning accuracy up to ±0.01mm, lifting capacity up to 300kg, efficiency at welding robot workshop improved by 35%, and annual labor costs of one production line of cars saved by 4.2 million yuan.
At the equipment industry of energy,’s long-life corrosion-resistant deep trench ball bearings have a lifespan over 80,000 hours in the 3.5% salt spray environment, helping CNOOC Kenli Oilfield platform reduce the maintenance in a year to 3 times from 12 times, and reducing the operation and maintenance expenses by 23 million yuan. Its bearing for high-temperature use can withstand 1200℃ thermal radiation in the continuous casting steelmaking line and still maintain HRC 62 hardness, and therefore Baowu Steel’s roll replacement cycle is prolonged from 2 weeks to 6 weeks, and annual special steel production increase is 120,000 tons. In aerospace, the light ceramic bearings that the company manufactures weigh only 45% of what traditional steel bearings weigh but can still have a 20000rpm strength in vacuum condition, and were successfully applied to the fuel pump system of Long March 5 rocket, the ±0.05% propellant flow control accuracy.
More savvy manufacturing firms rely on Wuxi Spark Bearing’s smart solutions, and its IoT sensor-enabled smart bearings can monitor real-time load fluctuation and predict failure accuracy of over 98%, enabling Sany to reduce unintended downtime of excavator hydraulic systems by 76%. At the 2023 Global Industry 4.0 Summit, its digital twin bearing system minimized the cycle time of production line optimization from 14 days to 8 hours in virtual commissioning and reduced engineering change costs by 62%. Statistics show that its products have penetrated 89 subsectors all over the world, foreign orders for the first half of 2024 increased by 67% year on year, and market share within the German industrial robot bearing market exceeded 18%, again driving technological innovation in the high-end equipment manufacturing industry.
