miniature ball bearings Regular maintenance and inspection of bearing

Play and its performance to maintain ball bearings long-term to make the bearing fully, must cogent do regular maintenance (check). Double Row Ball Slewing Bearing Through regular check for proper, do early detection of failure, to prevent accidents, is very important to improve the productivity and economy.
1, cleaning
Remove the bearings when the examination, using methods such as photographic appearance record. In addition, to confirm that the remaining amount of lubricant and lubricant sampling, and then cleaning bearings.
A bearing cleaning, rough cleaning and washing, and the metal frame at the bottom of the container placed on the use of.
B, rough when washing, Full complement cylindrical roller bearings use the brush in the removal of grease or oil adhesion. At this point if oil bearing, attention will be due to foreign bodies such as damage the rolling surface.
C, sperm washing, slowly rotating bearings in oil, be careful.
Cleaning agents are commonly used as neutral without water diesel or kerosene, sometimes using temperature as needed, such as lye. No matter what kind of cleaning agents, are often filtered clean.
After cleaning, immediately on the bearing coating antirust oil or antirust grease.
2, examination and judgment
In order to determine the bearing removed can re-use, to check on the accuracy of rotation accuracy, internal clearance, and the mating surfaces, raceway, cage and sealing ring.
About the examination results, can be thin wall bearings judged by the bearing or bearing are used in.
Criteria based on the mechanical properties and the important degree and the inspection cycle and different. If the following injury, bearings shall not be re used, must be replaced.
1) bearing parts of the fault and defect.
2) the raceway surface rolling surface stripping.
