Talking about the factors affecting the service life of angular contact ball bearings

Angular contact ball bearings can achieve a longer service life than traditional calculations suggest under ideal operating conditions. This is particularly true when the load is light, or when contaminants are effectively separated and controlled by the lubricating film formed between the rolling surfaces (raceways and rolling elements). In such cases, surface damage to the rolling components is minimized, leading to extended bearing life. However, in real-world applications, various factors can significantly impact the performance and longevity of these bearings. Here's a brief analysis of some common issues: (1) Poor Lubrication Lubricants used in angular contact ball bearings have specific temperature ranges for optimal performance. If the temperature rises too high, the lubricant may degrade, losing its ability to provide proper lubrication. This can lead to excessive friction, overheating, and even burning of the bearing. Additionally, using low-quality lubricants or failing to replenish them during operation can also cause abnormal noise, increased temperatures, and reduced bearing life. (2) Rotor Imbalance Before assembly, the rotor of most equipment should be dynamically and statically balanced to prevent unnecessary stress on the bearings. However, over time, rotors can become unbalanced due to corrosion from the medium they operate in, wear from solid impurities, or bending of the shaft. This imbalance creates centrifugal forces that result in heat, vibration, and severe wear on the raceway, potentially leading to complete failure of the bearing. (3) Inadequate Inspection and Replacement Regular inspections are essential to ensure the continued safe operation of angular contact ball bearings. If signs of overheating, unusual noises, or vibrations are detected, the machine should be stopped immediately to identify and resolve the issue. Bearings showing severe fatigue, pitting, cracking, or reduced hardness (below HRC 60) should be replaced promptly. Delaying maintenance can result in serious damage to the bearing or even the rotor, disrupting normal operations. Furthermore, improper removal of the bearing or loose anchor bolts can cause indentation, cracks, or damage to the inner and outer races. By addressing these issues proactively, the lifespan and reliability of angular contact ball bearings can be significantly improved. Always follow manufacturer guidelines for maintenance and replacement to ensure optimal performance. *Image: Global hardware network* *Concerned about surprises* **Tags:** Factors Affecting the Service Life of Angular Contact Ball Bearings **Previous:** Analysis of the Difference Between Hydraulic Press and Ordinary Punching Machine **Next:** Characteristics and Use of Some Pneumatic Tools
