Why lubricate the bearings of electric vehicles?

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. Water will wash off the grease in the bearing, resulting in poor lubrication and rust. 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 balls with kerosene and dry them with a cloth. Then use clean fingers to pick some butter on the fairway of the steel bowl, and then evenly load the steel balls 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 be inward and in contact with 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 thin lubricating oil is injected, the original oil dilution flow will reduce the lubricating 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.
