Application Development of Cylindrical Roller Bearing for High-speed EMUs

Blog Article

Aiming at the problems of tapered roller bearings applied in high-speed EMUs in our country, such as bearing grease leakage, abnormal temperature rise, and stripping, using Bike Parts - Headsets forward design concept, combined the technical characteristics of cylindrical roller bearings of radial load capacity, high speed limit, strong maintaining lubrication capacity, the cylindrical roller 2 Pc. Living Room Package w/ Chair bearings were developed for high-speed EMUs operation.Through the bench test, line test and batch applications, the proposed cylindrical roller bearings were validated to meet the application requirements of high-speed EMUs.
