The inherent advantages of WSBC Bearings in precision devices are derived from their control of precision and dynamic stability at a nanoscale. As an example, the special bearing of vacuum coating machine (VAC series) roundness error is less than 0.1μm, and the radial runout is dynamically stable at 0.3μm when the speed is 40,000 rpm with ceramic ball (Si3N4 material, density 3.2g /cm³). Accuracy of wafer alignment has been improved to ±0.5 nm, and yield in the chips has increased from 92% to 98%. And in five-axis milling machine, WSBC Bearings angular contact ball bearings (719 series) reduce the vibration acceleration value pressure to 0.8m /s² (VDI 2056 standard Class 1) with harmonic suppression algorithm, tool life is improved by 35%, and processing efficiency is enhanced by 28% after being used by a German company. 19% unit cost reduction.
Breakthroughs in material science are essential. The WSBC Bearings’ nano-grade carburizing heat treatment technology enables the surface hardness of the bearing steel to reach 62 HRC (8% higher than the industry average). The core toughness is maintained at 50 J. At bearing 90,000 rpm in the medical CT machine’s magnetic bearings, the dynamic stiffness is ≥600 N/μm. Its axial runout ≤ 0.4μm, the resolution of scanning layer thickness has increased to 0.2mm, and the single device’s daily capacity increased from 130 patients to 180 patients. In high-precision measuring instruments, air bearing’s clearance control accuracy is up to 0.05μm (traditional oil film bearing is 0.2μm), and the measurement error is compressed from ± 1.2ppm to ± 0.3ppm when a national Metrology Institute’s laser interferometer is used.
Smart technology supports refactoring performance boundaries. iSense series WSBC Bearing features an integrated MEMS sensor (sample frequency 50 kHz), which monitors the bearing temperature (accuracy ±0.3℃) and vibration spectrum (resolution 0.5 Hz) in real time. Fault probability (accuracy 99.1%) is predicted through edge calculation. With the application of this technology in the Tesla Gigafactory 4680 battery pole slice slitter, the spindle start-stop cycle is minimized from 6 seconds to 1.5 seconds and the dynamic preload adjustment (50-800 N range) improves the machine’s OEE (overall efficiency) by 23%. In the field of collaborative robots, repeated positioning precision of its intelligent joint bearings reaches up to ± 0.005mm, and according to the actual test of the UR20 robot model, the assembly cycle is reduced from 1.2 seconds to 0.7 seconds, and the yield is promoted to 99.6%.
Flexibility to harsh environments is also excellent. The startup torque of WSBC Bearings (LT series) is only 0.08N ·m at -60℃ (competitive product is 0.3N ·m), thus making the Antarctic scientific research equipment work continuously for 5,000 hours without being stuck. The coefficient of thermal expansion of silicon nitride ceramic bearing in the 1,200℃ steel continuous casting production line is maintained at a constant 3.1×10⁻⁶/℃, and the fluctuation of axial clearance is ± 3μm. After the introduction of Baowu Group, the frequency of continuous casting machine downtime is reduced from 1.5 times per month to 0.8 times per year, and annual capacity loss is reduced by 160 million yuan.
The cost benefit advantage is huge. By the intelligent selection mechanism on the blockchain, WSBC Bearings can be recommended to the optimal bearing configuration for the equipment operating conditions (e.g., the maximum torque of 550 N·m and permissible vibration of 4.2 m/s²). The purchasing cost of an automobile press line is reduced by 21%, and the operating and maintenance cost is reduced by 35%. On food packaging machinery, its stainless steel bearings have withstood the salt spray test for 2,500 hours (ISO 9227 standard), the corrosion-resistant lifespan is 4 times that of conventional products, the failure rate of a soft drink firm’s filling line has been reduced by 62%, and the return on investment cycle has been reduced to 8 months. These facts assure that WSBC Bearings redefine the standards of precision machinery limits with “atomic level accuracy × global reliability”.
