Bearing life cycle extension method

1 bearing installation
Whether the bearing is installed correctly affects accuracy, life and performance. Therefore, the design and organization department should fully study the installation of the bearings, and hope to install them according to the operating standards.
2, alignment, straightening
After the bearing is installed, alignment may result in additional loads, friction and vibration of the bearing if not carefully aligned. These may accelerate fatigue and bearing life and may damage the life of other machine parts. In addition, increased vibration and friction can greatly increase energy consumption and premature effectiveness risks.
3, basic condition detection
During use, it is often necessary to test the external conditions of the bearing operation, such as temperature, vibration and noise measurements. These regular inspections will identify potential problems early and will prevent unexpected machine stops, allowing production plans to be successfully implemented and increasing plant productivity and efficiency.
