Before using an INA bearing, the first step is to carefully inspect its appearance. Then, check whether the bearing meets your load requirements and specifications. The appearance of the bearing should be examined under good lighting conditions to detect any cracks or surface damage. These imperfections can lead to improper installation, causing excessive misalignment and potentially leading to early failure during operation.
Cracks or wear marks on the bearing surface are the most common issues to look out for. Such damages can prevent the bearing from being properly mounted, resulting in excessive eccentric loading. These defects may also cause premature failure, such as the bearing breaking down during normal use. Additionally, if the bearing shows a “skin†appearance—where the surface layer separates from the base metal—it indicates poor adhesion between layers. This condition can significantly reduce the bearing’s rotational accuracy and service life.
In addition to visual inspection, there are several other important factors to consider when dealing with INA bearings:
1. **Alignment Function of INA Bearings**: If the shaft’s centerline does not match the bearing housing’s centerline, or if the shaft bends due to external forces, the inner ring of the bearing may become misaligned. In such cases, it is recommended to use self-aligning ball bearings or SKF spherical roller bearings, which can accommodate slight misalignments and still perform effectively.
2. **Speed Considerations**: At normal operating speeds, the type of bearing selected typically doesn’t cause significant issues. However, at higher speeds, the choice becomes more critical. Each bearing type has a specific limit speed, defined as the maximum allowable speed when the load is low (P ≤ 0.1C) and the cooling conditions are normal. This value applies to bearings with a 0-level tolerance.
3. **Load Capacity**: When selecting a bearing type based on the load characteristics, pure axial loads usually require thrust bearings. For smaller axial loads, thrust ball bearings are suitable, while larger axial loads call for thrust roller bearings. Cylindrical roller and needle bearings are particularly sensitive to misalignment, and their load capacity decreases significantly when tilted. Therefore, it's best to avoid these types if the shaft rigidity or housing stiffness is low.
Beyond basic visual checks, the bearing expert from the China Bearing Network also emphasizes the importance of paying attention to subtle signs that may indicate potential problems. Early detection of these issues can help prevent unexpected failures and downtime.
