As we all know, the bearing is exposed to the outside and the seal is not good and easy to enter water, such as the right side bearing of the front wheel; the motor does not have a brake end cover. The inner test bearing and the oil seal are damaged. The large friction force causes the bearing to wear out and "fall apart". In this case, it is necessary to lubricate the bearings of electric vehicles. So what should be done?

      First clean the steel bowl and steel ball with kerosene and dry it with a cloth. Then use clean fingers to pick some butter and spread it on the fairway of the steel bowl, and then evenly load the steel ball into the fairway (the steel bowl is filled with steel balls). After that, there should be a half of the steel ball gap between the steel balls. If the ball frame type steel ball is used, the steel ball should face inward and touch the steel bowl. Do not install the steel ball frame backwards), and then coat the outside of the steel ball. Apply a layer of butter and flatten it with your fingers.

      The rolling bearings of electric vehicles should be lubricated with butter to maintain long-term lubrication performance. If injecting thin lubricating oil, the original oil dilution flow will reduce the lubrication performance and anti-rust effect for a long time; and other movable parts such as chains, flywheels, workshops, etc., thin lubricating oil should be added.
