What factors will affect the performance of the cage?

There are many factors that affect cage performance. The following are some of the main factors:

1. Lubrication status: If the lubricating grease added to the bearing is of the wrong grade or there is a problem with the quality of the grease, or the lubricating oil dries out after the bearing has been running for a long time and is not added in time (maintenance), it will intensify the friction between the bearing rolling elements and the cage, causing damage. Invalid.

2. Impact load on the bearing: The intense vibration in the impact load causes the rolling elements to impact the cage, causing damage to the cage.

3. Bearing cleanliness: If the bearing is not well sealed in the bearing box and dust enters, the friction between the rolling elements and the cage will increase, causing damage to the cage.

4. Bearing clearance: If the bearing is not installed in place, is tilted, or has excessive interference, etc., it will easily lead to a reduction in clearance, increased friction, abnormal peeling of the bearing surface, excessive peeling and entry into the cage pockets, which will lead to The cage operation is blocked and additional loads are generated, aggravating the wear of the cage.

5. Cage material: If the material is not suitable, such as insufficient strength, poor toughness or poor corrosion resistance, it will easily fall apart. At the same time, if the material deteriorates or ages, it will also lead to a decrease in cage performance.

6. Installation problems: For example, if the bearing is installed incorrectly, the cage will be damaged during installation; the misalignment of the coupling will cause the bearing to be skewed, the rolling elements and the cage will be stressed unevenly; the belt will be installed too tight, etc.
