Research and application of key technologies of rolling bearings for freight cars with large axle and heavy railroads. Through in-depth and independent intellectual property research on the design, manufacture and test of freight cars bearing on large axle heavy railways, the research and development of freight cars bearing on large axle heavy railways has been completed. Compared with the well-known foreign company's products, the performance is comparable with that of foreign products, which can replace the imported bearings completely and realize the railway truck supporting heavy load (30t axle weight). The successful development of this product has broken the situation that axlebox bearings of large axle heavy railways have been monopolized by foreign countries and ensured the successful completion of the research on the technology of long axle heavy haul freight trains in China. At present, the project product has been loaded in the vehicle factory car more than 3,000 vehicles.
Through the implementation of the key technology research and application project of rolling stock bearing on truck axle, Wazhou Group broke through the key technology of truck axle bearing on large axle heavy railroad and built the research and development platform and industrial base of truck axle bearing on large axle heavy railroad, and upgraded the railway freight car bearing Product design and manufacturing level and market competitiveness.
