WSBC Bearing product matrix crosses the whole industrial field, its deep groove ball bearing (6000 series) inner diameter ranging from 3 mm to 500 mm, dynamic load capacity up to 156 kN (C/P value 0.25), in the automotive hub to achieve L10 life of more than 300,000 kilometers, a new energy vehicle company tested, after replacing the conventional bearings, energy consumption is saved by 8%, and the annual mileage of a single vehicle is increased by 1,200 kilometers. For heavy machinery, the surface hardness of the self-alighting roller bearing (223 series) is increased to 62 HRC by nano-carburizing technology, and the life of the roller bearing is 3,500 hours under the peak impact load of 3,800 kN in the mine crusher (the average of competitive products is 1,200 hours), and the rate of equipment shutdown is reduced by 58% after application in an Australian iron ore business. $2.3 million in maintenance cost savings per year.
Ultra-high precision angular contact ball bearings (719 series) specially designed for high-speed machine tools, Si3N4 ceramic ball (density 3.2g/cm³) and super grinding raceway (roundness error ≤ 0.15μm), temperature rise only 10℃ at 24,000 rpm. Vibration acceleration ≤ 0.8m/s² (VDI 2056 standard Class 1). Comparative experiments by a German five-axis machining center supplier show that its processing efficiency is 22% higher and the tool life is extended by 35%. In the semiconductor sector, the vacuum coated bearing (VAC series) discharge rate is < 5×10⁻¹¹ Torr·L/s under an environment of 10⁻⁷ Pa, which allows the wafer alignment error of the lithography machine to be less than 0.01 nm. It is confirmed by ASML that it can reduce mask plate loss by 30%.
Extreme environment adaptation products are as follows: high-temperature ceramic bearings (HX series) are made of silicon nitride material (thermal expansion coefficient 3.1×10⁻⁶/℃). Axial clearance has ± 3μm variation in the continuous casting production line at 1,200℃. After the implementation of Baowu Group, the frequency of downtime in continuous casting machines is reduced from 1.8 times a month to 0.5 times a year, and the annual production capacity is increased by 210 million yuan. The polar special low-temperature bearing (LT series) has a starting torque of only 0.08N ·m at -60 ° C (standard product 0.3N ·m), ensuring 5,000 hours of faultless operation for the Antarctic scientific research snowmobile drive system, and enhancing the equipment availability rate from 72% to 96%.
The smart bearing (iSense series) integrates MEMS sensors to monitor the vibration spectrum (0-50 kHz) and temperature (accuracy ±0.3 ° C) in real time, and calculates the probability of failure through edge computing (accuracy 98.5%). After the retrofit of a 5 MW unit in a European wind farm, the frequency of unplanned mainshaft bearing downtimes decreased from 1.5 times a year to 0.2 times a year, reducing generation losses by 1.8 million euros a year. In collaborative robots, its intelligent preload module dynamically controls the axial load (50-1,200N range), repeat positioning accuracy is up to ± 0.005mm, the measured assembly cycle time of UR20 robot model is shortened to 0.7 seconds, and the yield is increased to 99.6%.
Solutions based on specific requirements are also top-notch. WSBC Bearing’s four row cylindrical roller bearings (FC series) in the mill have a dynamic load capacity of 7,500 kN, and the L10 life is over 18,000 hours when the hot strip production line is below 2,800 tons of rolling force, and the roll system replacement frequency is reduced by 67% after a mill’s 1780 production line is used. Annual maintenance cost saved 9 million yuan. In food machinery, WSBC Bearing stainless steel deep groove ball bearings (440C material) achieved 2,500 hours of salt spray testing (ISO 9227 standard), 4 times the corrosion resistance life of traditional products, a dairy company filling line downtime cut by 60%, the return on investment cycle cut to 7 months. All these product lines are a verification of WSBC Bearing technical philosophy of “scenarios define performance.”
