Play its due performance and maintain long-term to make the bearing fully, must cogent do regular maintenance (check).
By periodically to check for proper, do early detection of failure, to prevent accidents, which is very important to improve the productivity and economy.
1, cleaning
Remove the bearings when the examination, first with the methods such as photographic appearance record. In addition, to confirm that the remaining amount of lubricant and lubricant sampling, then clean the bearing.
A bearing cleaning, rough cleaning and washing, and metal frame at the bottom of the container to use on.
B, rough when washing, use a brush in oil removal of grease or adhesions. At this point if oil rotary bearing, note that due to foreign body injury such as a rolling surface.
C, when sperm washing, slowly rotating bearings in oil, be careful.
Cleaning agents are commonly used as the neutral water diesel oil 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 dismounting can re-use, to check on the size precision, accuracy of rotation, internal clearance and the matching surface, raceway, cage and sealing ring.
On examination results, can be judged by using inertial bearing or bearing are proficient in.
Criteria based on the mechanical properties and the important degree and inspection cycles and different. If the following injury, bearing must not be re used, must be replaced.
1) bearing parts of the fault and defect.
2) the raceway surface of roll surface stripping.
