How to calibrate angular contact ball bearings?
As a high-precision bearing, angular contact ball bearings are widely used in precision machinery, high-speed rotating equipment and other fields.
However, in the process of use, how to ensure that its performance is in the best state requires precise calibration.
Simply put, calibration is to measure and adjust the parameters of angular contact ball bearings to meet the design requirements and maintain good motion performance.
Generally speaking, we need to start from the following aspects:
Installation accuracy:
When installing angular contact ball bearings, it is necessary to ensure that the coaxiality,
verticality and other parameters of the shaft and seat hole meet the requirements.
Therefore, during the calibration process, we need to use professional measuring tools to accurately measure the size, shape, etc. of the shaft and seat hole,
and make necessary adjustments.
Preload:
Angular contact ball bearings usually need to apply a certain preload to eliminate internal clearance and improve the rigidity and rotation accuracy of the bearing.
Therefore, when determining the preload, we need to comprehensively consider factors such as the specifications and working conditions of the bearing,
and make adjustments through actual measurements.
Lubrication:
Good lubrication is one of the key factors to ensure the normal operation of angular contact ball bearings.
During the proofreading process, we need to check whether the type, quantity and quality of the lubricating oil meet the requirements.
If the lubricating oil is found to be deteriorated or insufficient, it should be replaced or supplemented in time.
In addition, we also need to pay attention to maintaining the cleanliness of the lubricating oil to prevent impurities from entering the bearing.
Temperature control:
Angular contact ball bearings will generate a lot of heat during high-speed operation. If the heat is not dissipated in time,
it will cause problems such as overheating and increased wear of the bearing.
Therefore, take effective measures to control the temperature. For example, air cooling, water cooling and other methods can be used for cooling; 
By accurately proofreading angular contact ball bearings, we can effectively improve the service life of the bearings and the operating efficiency of the equipment.
Of course, in addition to the above-mentioned aspects, there are other details that need to be paid attention to.
I hope that everyone can continue to sum up experience and lessons in future work and continuously improve their professional level.
