Bearing is a very important component, but if you do not pay attention to protection and correct use, it is easy to form rust and affect normal use. How to maintain it normally?

1. Appropriate cleaning methods should be selected according to the material function and environmental conditions of the gantry crane. Common cleaning methods include chemical cleaning, mechanical cleaning and solvent cleaning. It should be noted that the appearance after cleaning should be dry. You can use filtered dry compressed air to dry, or you can use a dryer to dry. In addition, under simple conditions, the bearings can also be wiped dry with cotton cloth.
2. On the basis of cleaning, apply appropriate anti-rust oil with anti-rust oil. The application of anti-rust oil should be based on the use and size of the single-girder crane to select a suitable coating method.

The method of applying anti-rust oil is as follows:

1. Spraying method: For large cranes, the spraying method will be more suitable and convenient. It is suitable for solvent-diluted anti-rust oil or thin-layer anti-rust oil, but it must adopt perfect fire protection and labor protection measures for safety protection.
2. Immersion method: For smaller bearings, they can be soaked with anti-rust grease to make the grease adhere to the surface of the bearing and play a protective role. The thickness of the oil film can be adjusted according to the actual situation, and the temperature and viscosity can be adjusted;
3. The above are two important aspects of how to prevent the bearing of gantry cranes from rusting. One is cleaning, and the other is to choose a suitable anti-rust oil alteration method to prevent corrosion more safely and effectively, and then make it work.
