When dealing with IKO imported bearings, it's crucial to understand the common issues that may arise during operation. These problems can affect performance, lifespan, and overall system efficiency. Here are some typical problems and their underlying causes:
1. **High Temperature in IKO Bearings**:
During normal operation, the bearing should remain at a stable temperature. If the surface feels excessively hot when touched, it could indicate a problem. Common causes include poor-quality lubricant, high viscosity of the oil, tight fitting of the device, incorrect installation, or excessive load on the bearing. Additionally, damage to the rolling elements or cage can also lead to overheating.
2. **Abnormal Noise from Bearings**:
Bearings usually operate with a smooth and quiet sound. However, if loud noises, irregular sounds, or impacts occur, it may signal an issue. Possible reasons include wear on the inner or outer rings, which disrupts the alignment between the bearing and the shaft or housing. Other factors include lack of lubrication, dry friction, or loose cages leading to internal damage.
3. **Detachment of Raceway Surface**:
The raceways and rolling elements are subjected to periodic stress during operation. Over time, this can cause fatigue and material loss. Excessive load, improper installation, or misalignment of the shaft can accelerate this process. Such damage reduces precision and can result in vibration and noise.
4. **Bearing Burning**:
A burned bearing often shows discoloration due to heat. This typically happens due to insufficient lubrication, low-quality oil, or excessive tightness in the installation. It is important to ensure proper lubrication and correct fitment to avoid this issue.
5. **Plastic Deformation**:
Pits or uneven surfaces on the raceway or rolling elements can indicate plastic deformation. This occurs when the bearing is exposed to heavy static or impact loads beyond its yield limit. This condition is more common in bearings operating at low speeds.
6. **Cracks in the Bearing Housing**:
Cracks in the housing can be caused by excessive tightness in the bearing fit, foreign particles, or deformation of the housing itself. Poor machining of the bearing seat can also contribute to this problem.
7. **Cage Damage**:
A broken cage can result from inadequate lubrication, damaged rolling elements, or misalignment of the bearing. This can lead to failure of the entire component.
8. **Adhesion of Cage Material to Rolling Elements**:
This issue arises when the rolling elements become stuck in the cage or when there is insufficient lubrication. It can lead to increased friction and potential damage to the bearing.
9. **Severe Wear on the Raceway**:
Foreign objects entering the bearing, lack of lubrication, or using an incompatible lubricant can cause severe wear on the raceway. Regular maintenance and proper lubrication are essential to prevent such damage.
