Requirements for new energy vehicle bearings: long life, creep resistance, high speed, low friction, and low vibration. The bearing speed can reach 16000-18000 revolutions per minute or even higher, so the requirements for bearings under high-speed conditions are also very strict. In addition to the quality requirements of the bearings themselves, there are also high requirements for the bearing units. For example, when assembling bearings and end caps, if the bearings are misaligned, a bearing resistance loss friction test will be conducted in the subsequent process. If the bearing friction is too high, it will not pass. The pressing of bearings and end caps is an application of servo presses and servo presses, which now require precise control of force and displacement to ensure product quality.
