    Tips: How to deal with the rust of the motor bearing seat in the ball screw?

    The reason for the rust of the motor seat bearing is very complicated. It may be that the bearing has not been properly treated with rust, it may be the rust caused by moisture, and the paint mist may also cause rust. It is closely related to the type of insulating varnish, bearing pre-filled grease, the treatment method of the motor paint, and the storage environment of the motor seat.
    To prevent paint rust, we must first improve the anti-rust ability of the bearing itself. The material of the bearing is generally bearing steel, and the method of anti-rust treatment is generally to coat the inside of the bearing with anti-rust oil. After the anti-rust treatment, the motor seat factory will add grease by itself. However, if the anti-rust oil is applied too thickly, the lubrication performance will decrease. Although attention should be paid to improving the anti-rust performance of the grease, which has a certain effect, the most effective method is to change the composition of the paint.
