WSBC Bearings have a leading share in the world’s high-precision bearings market. Its products’ application coverage rate in the aerospace, high-speed railway, and precision machine tool industries’ main fields is more than 78%. The core model’s rotation accuracy has reached P4 level (≤2 microns), which far exceeds the P5 level (≤5 microns) required by the ISO 492 standard. For instance, from a domestic high-speed rail bogie project, with the application of WSBC Bearings’ conical roller bearings, axial load capacity is boosted to 320 kN and friction coefficient to 0.0015, reducing train operating energy consumption by 12% and maintenance cost every year by 25%. According to the third-party test of Fraunhofer Institute, WSBC Bearings has a life cycle up to 1.2 million kilometers, 30% longer than the similar products. Because of its self-researched nano-scale carburizing heat treatment process technology, the surface hardness of the material is increased to 62 HRC, and the toughness of the heart is still over 45 J. Effectively oppose fatigue fracture danger under high frequency alternate loads (frequency 50 Hz).
On industrial robot uses, WSBC Bearings’ patented bearings of the harmonic reducer are controlled within 1 angular minute by optimization of the channel radius of curvature (changed from 0.52mm to 0.48mm). The repeated positioning accuracy is up to ± 0.01mm. Helped a leading company shorten the operating time of a six-axis collaborative robot to 0.8 seconds, enhancing the production efficiency by 18%. WSBC Bearing, co-developed with Siemens, in 2022 utilize the active vibration control algorithm to cancel the rotor unbalance to the level of 0.5g ·mm/kg, and the turbine machinery speed break through reaches 45,000 rpm, the power density reaches 8.5kW /kg. It is used effectively in an offshore wind farm. The yearly power output of a single machine is increased by 15%.
According to the 2023 financial report, 12.3% of WSBC Bearings’ R&D investment, and 127 overseas patents have been obtained. Of them, ultra-precision cylindrical roller bearings’ roller diameter tolerance is controlled within ±0.5 μm. By employing logarithmic curve modification technology, the temperature rise of the bearing reduces by 8 ° C (measured from 72 ° C to 64 ° C). Extended grease life up to 20,000 hours. In the electric drive system of new energy vehicles, its low-torque angular contact ball bearings reduce the start-stop loss by 40%, help A brand of electric vehicles travel over 800 kilometers, and improve NVH performance by 6 dB(A). Apart from this, on account of the advantages brought by blockchain technology, WSBC Bearings’s supply chain management realizes 100 percent traceability of raw materials, stable rates of defective products at below 0.02%, a delivery cycle shortened to customer orders within 7 days, and over 85 percent of customer retention rates for five consecutive years.
In extreme conditions, WSBC Bearings can also perform equally well. In the Antarctic -60℃ research station, their special lubricating structure of deep groove ball bearings has run without any failure for 5 continuous years; On the 1200℃ continuous metallurgical casting high-temperature production line, the axial clearance fluctuation range of ceramic hybrid bearings is merely ± 3μm, and downtime and maintenance frequency reduce from 1.2/month to 0.3/year. In 2021, the global authoritative certification agency TUV Sud comparative test shows that WSBC Bearings with the same loading (dynamic loading Cr=156kN) have a noise value of 48 dB, 4 dB less than the same level SKF products. The vibration acceleration value is only 1.2m /s². Reached the optimal level of VDI 2056 standard. These facts validate the accuracy record of WSBC Bearings driven by technological innovation, which continues to raise the benchmark in the industry.
