轴承属于电动车前后轮中的易损件，轴承损坏也是电动车维修当中的常见故障，如果驾驶者在骑车过程中有车轮异响，摆动，运转吃力等情况出现，都有可能是轴承损坏。
轴承易坏的原因：
1、轴承质量问题。
2、轴承裸露在外（如前轮右侧轴承），或油封损坏（如后电机轴承），如遭遇雨水天气，会将轴承内黄油冲刷掉，导致润滑不良和生锈，使轴承过早磨损。
3、车轮遭受重创或轴杆硬度不够导致弯曲变形，会使轴承在运转过程中偏向受力，俗称“相劲”，使轴承过早损坏。
4、轴承孔加工偏心，即两个轴承不在一条中心线（多见于低档三轮车前轮）。
5、轴承孔加工精度不够，太紧失圆，轴承过盈配合之后产生轻微变形，运转阻力增大，导致轴承过早磨损。
6、轴承孔磨损松旷，轴承孔与轴承过盈量不够，在使用过程中会使轴承孔磨损加快，配合间隙加大，久而久之造成车轮晃动，轴承跑外圈的现象。
如何解决这些问题呢？
1、选择高质量配件。
2、更换轴承同时检查油封，酌情予以一并更换，对于直接裸露在外的轴承要告知顾客注意防水，定期检查加注润滑脂。
3、轴承更换安装完毕，要支起车轮悬空，检查车轮运转是否灵活顺畅，有无吃力或卡滞现象，若有则根据以上第3.4.5项故障原因予以排查。
4、对于出现轴承孔松旷这一类故障，出于对维修效果及使用安全性方面的考虑，应对车圈或电机盖予以更换。
