How to paint large sized precision bearings?
Bearings are widely used, and super-large precision bearings are used in some special occasions. Due to the relatively large size of such bearings, some of the processing difficulties for them are also more difficult than ordinary bearings. Today we will talk about the requirements of the specifications to be followed when painting oversized bearings.
First of all, it is impossible to achieve this goal by only brushing the super-large bearing once, so it is necessary to rub the super-large precision bearing 2 to 3 times or even more times to thicken the coating thickness. In the process of brushing, every time the coating is added, it is necessary to ensure that the thickness of the coating on the bearing surface is increased by 30 nanometers to 1 micrometer, so that the friction resistance and wear resistance of the bearing can also be improved. In addition, the time and temperature of each brushing interval should be well grasped, and the paint surface should not be sticky before the next brushing, but the interval should not exceed 8 hours. In addition, the time for the 1st to 3rd times of the super-large precision bearing is 0-5 hours; the time for the 4th to 8th times is 6-12 hours, and this principle is strictly followed as much as possible.
