Ways to Extend the Life of Rolling Bearings

The life of the roll neck bearing is closely related to the bearing design, production process, installation and use, so it is necessary to do the best at each stage in order to make the bearing reach the best operating condition and prolong the service life of the bearing. Today, Luoyang FV will introduce the methods to extend the life of bearing.

1. The dimensional tolerances of bearings and shafts should be in the best condition. The bearing is mounted on the shaft and should rotate easily. If it is inconvenient to rotate, it means that the size of the shaft is too large, please reduce the dimensional tolerance. After the bearing is pressed into the shaft, if the rotation has a noticeable "loose" feeling, the dimensional tolerance of the shaft may be large, or the concentricity of the shaft may not be good.

2. Installation method of rolling bearing: Since the bearing is a high-precision commodity, poor installation will easily damage the cross section of the bearing. When pressing the shaft, only apply force to the circle, and when pressing the large circle, only apply force to the large circle. When installing a standard air or hydraulic press, if deflection occurs, the section of the bearing will be destroyed, and the wire of the bearing will be broken.

3. Avoid contamination: When the bearing is placed on the rotor of the motor to realize the dynamic balance of the rotor, the iron pins generated due to the dynamic balance of the rotor can easily enter the bearing, so the rotor is kept in good dynamic balance before installing the bearing. In order to facilitate installation, some manufacturers use vegetable oil to achieve lubricating effect, which is easy to contaminate the inside of the bearing.

4. Prevent paint rust: The characteristic of paint rust is that it is a closed motor. The sound of the motor is very good when it is installed, but after being placed in the warehouse for a period of time, the sound of the motor becomes very loud, and the bearing is disassembled. There are serious problems: Rust condition. The appropriate method should be selected according to the characteristics of the rusted surface and the specific conditions at that time. Generally, there are organic solvent cleaning method, organic liquid cleaning method, and mechanical equipment cleaning method. At the same time, the surface can be dry and clean: it can be dried with an air dryer or cleaned with a clean emery cloth.

The above is how to extend the service life of rolling bearings. If you want to know more, you can contact us at any time! Luoyang FV Bearings is always at your service.
