NSK bearings use life cycle extension method

Release time:2021-12-17

NSK bearings use the method of life cycle extension. In order to make the service life of NSK bearings longer, we will share with you today the method of extending the life cycle of NSK bearings. Hope it can be helpful to everyone.

1. Installation of NSK bearing

The correct installation of NSK bearings affects accuracy, life and performance. Therefore, the design and assembly department must fully study the bearing installation. Hope to install in accordance with operating standards. The work standard items are usually as follows:  

(1) Clean the bearing and its related parts;

(2) Check the dimensions and finishing conditions of related parts;

(3) Installation;

(4) Inspection after the bearing is installed;

(5) Supply lubricant.

2. Alignment and straightening

After the bearing is installed, if the alignment is not carried out carefully, the alignment may cause the bearing to suffer additional load, friction and vibration. These may accelerate fatigue and reduce the service life of the bearing, and may damage the service life of other machine parts. In addition, increased vibration and friction can greatly increase energy consumption and the risk of premature failure.

3. Basic condition monitoring

During use, it is necessary to frequently monitor the basic external conditions of bearing operation, such as temperature, vibration and noise measurement and so on. These regular inspections will detect potential problems early and prevent unexpected machine stoppages, so that the production plan can be realized, and the productivity and efficiency of the factory will be improved.

4. Lubricate again

In the process of operation, NSK bearings require correct relubrication to perfect its performance. The method of bearing lubrication is divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, it is necessary to choose a lubrication method suitable for the use conditions and purpose. If only lubrication is considered, the lubricity of oil lubrication is dominant. But grease lubrication has the advantage of simplifying the structure around the bearing.
