NTN rolling bearings are widely used in various mechanical systems. However, during their operation, the performance of these bearings can be affected by both internal quality and external factors. This may lead to changes in load capacity, rotational accuracy, and wear resistance. When the bearing's performance falls below the required level, it can result in defects or even failure. In such cases, equipment may stop working, making it essential to quickly identify the cause and implement appropriate solutions.
Common causes of abnormal phenomena in NTN bearings include:
- **Improper Lubrication**: Using expired or incorrect lubricants, overfilling grease, or having an excessive oil level.
- **Contamination**: Foreign particles like dust, sand, carbon powder, water, acid, or paint entering the bearing housing.
- **Incorrect Installation**: Improper installation methods, such as hitting the bearing directly with a hammer, or damaging the seal due to contact with other components.
- **Misalignment**: Shaft bending, misaligned shoulders, or incorrect fitting between the shaft and bearing.
- **Clearance Issues**: Excessive clearance leading to shaft vibration or improper fit.
- **Lack of Internal Grease**: Insufficient lubrication causing increased friction and wear.
- **Poor Maintenance**: Failing to clean debris from the bearing housing or not maintaining proper sealing.
These issues can significantly impact the performance and lifespan of NTN bearings. Therefore, regular maintenance, correct installation, and proper lubrication are crucial to ensuring the smooth operation of machinery.
In addition to these, improper tightening of the bearing sleeve due to a small shaft diameter can cause slippage, leading to scratches on the rolling elements. The inner diameter of the bearing housing must also be correctly sized to prevent distortion of the outer ring or seal cover.
By understanding these common causes, engineers and technicians can take preventive measures, reducing downtime and improving the reliability of mechanical systems that rely on NTN bearings.
