Important Considerations for the Maintenance of Imported Bearings

---

When performing regular maintenance on equipment that uses imported bearings, it is crucial to carefully inspect and evaluate the condition of the removed bearings. This includes checking not only the bearings themselves but also the surrounding components that may have been affected during operation. Proper documentation of these findings helps determine whether the bearing parts can be reused or need replacement. It's essential to thoroughly examine the appearance of the removed bearings, paying close attention to any signs of wear, damage, or abnormal conditions. Checking the remaining lubricant level is also important, as it can indicate how well the bearing has been maintained. Cleaning the bearings properly before reinstallation or storage is a key step in extending their service life. Next, you should inspect the raceway surface, rolling elements, and the cage for any signs of damage, wear, or misalignment. Special attention should be given to the running track of the raceway, as this area is most susceptible to wear over time. The decision to reuse a bearing depends on several factors, including the extent of damage, the machine’s function, its importance, operating conditions, and the scheduled inspection interval. If during the inspection, you find that the bearing is damaged or shows abnormal behavior, it is important to investigate the cause based on the visual damage and take corrective actions accordingly. If any of the following issues are present, the bearing should no longer be used and must be replaced with a new one: - Cracks or fractures in either the inner or outer ring, the rolling elements, or the cage. - Flaking or peeling on the inner and outer rings or rolling elements. - Obvious scoring or damage on the raceway, ribs, or rolling elements. - Severe wear or loose rivets on the cage. - Rust or defects on the raceway or rolling elements. -明显的 indentations or marks on the rolling surfaces or rolling elements. - Creep on the inner diameter of the inner ring or outer diameter of the outer ring. - Severe discoloration due to overheating. - Severe damage to the seal or dust cover of a sealed bearing. Maintaining accurate records of all inspections and replacements is essential for tracking the performance and longevity of your bearings. Regular maintenance not only ensures the smooth operation of machinery but also helps prevent unexpected failures and costly repairs.
