铁路机车车辆的Bearing是指轴承套,还不是关键技术。但shaft, 机车车辆轮对的那一根根轴承,才是材料和制造工艺的象牙塔,高技术,据说现在在复兴号上才开始使用国产的产品,以前一直靠进口。
WTF. I took subways in four cities in China and did not see a single service stop. If 敬业, 保障人民安全 is the case, I probably did not even know my life was on the line so many times. Down with China subways.很敬业,本着保障人民安全的精神,赞[emoji106]
小问题拉,全部更换轴承,土豆卖单,不给太华人民增加负担。All trains on Ottawa's Confederation Line LRT have been stopped and all stations have been closed because of a bearing issue that was discovered during a routine inspection. All LRT service suspended due to bearing issue

Transit services general manager Renée Amilcar said in a message to the mayor and city council that the decision was made in the interest of safety.
轴承完了,重大安全隐患,全部停运。

质量不好一定是中国货,如果不是中国货那就是中国风过来给吹坏了!赞内行科普!不知道这轴是谁生产的,偷工减料了吧。

这就是不能完全脱钩的原因,必须留几个非关键部件给土工国生产,以后背锅肯定用的着;不过话说回来,土工国质量好就没必要走低价路线,何必那么糟蹋自己。质量不好一定是中国货,如果不是中国货那就是中国风过来给吹坏了!![]()
