What is the effect of radial clearance adjustment on service life of bearings?

Each bearing has a pre-calculated service life. However, studies show that not all bearings can achieve this service life for various reasons. In the life cycle of bearings, some stages have an important impact on the service life of bearings. These stages are installation and primary lubrication, alignment, supplementary lubrication, basic condition monitoring and disassembly.
These stages in the bearing life cycle are very important to obtain the maximum service life of the bearing. By properly performing maintenance and using the right tools, you can significantly extend the life of bearings and improve factory productivity and productivity.
Including temperature, noise, speed and vibration measurement instruments during operation, it is important to regularly detect the state of the bearing using basic condition monitoring means, such as temperature, vibration and noise measurement. Regular testing can identify potential failures and help prevent unexpected shutdowns. Therefore, equipment maintenance schedule can be arranged in accordance with the production schedule to improve the productivity and production efficiency of the factory.
The commonly used methods to adjust radial clearance of bearings are as follows:
1, for multi oil wedge fixed bearing, in principle, it is not allowed to repair, scrape and adjust the bearing gap, the gap should be replaced when appropriate.
2. For the backlash of cylindrical and oval bearing bush, it can be adjusted by manual scraping or repairing and scraping after partial surface of bearing with cushion turning
3, the top clearance of cylindrical and oval bearing bush can be adjusted by manual scraping or the method of adding pad in the bearing when the situation permits.
4. For multi wedge tilting bearing, it is not allowed to repair and scrape tiles. If the gap is not suitable, tiles should be replaced. For the tile with adjustable thickness, stainless steel pad can be added under the tile back adjustment block, or the method of thinning adjustment block thickness can be used to adjust the tile amount. Note that for multi-wedge tilting bearing, the thickness error between the same group of tiles should be less than 0.01mm.
