To check the condition of SKF roller bearing grease, you can apply a small amount of grease between your two fingers. If there are contaminants, you will feel them. Alternatively, spread a thin layer of grease on the back of your hand and then close it. This helps detect any impurities. Next, replace the old grease with new one. Use an oily lubricant to clean out the old oil, and if possible, refill with fresh oil. Then rotate the machine at low speed for a few minutes. The oil will collect any remaining contaminants, which should then be drained. It is recommended to filter the oil before use to ensure its cleanliness. When using SKF bearings with smooth grease, make sure not to let the used tool come into contact with any part of the bearing. Residual fibers from the tool can get lodged between the rolling elements and cause damage. This is especially important when working with smaller bearings. After some time in operation, the vibration and noise levels remain stable, and the frequency spectrum is simple, showing only one or two harmonic frequencies. The three times power frequency component is rarely observed, indicating that the bearing is in good condition. As the bearing continues to operate, it enters the later stage of its life. At this point, vibration and noise begin to increase, sometimes accompanied by abnormal sounds. However, the rate of vibration increase is gradual. During this period, the kurtosis value of the angular contact ball bearing may suddenly rise to a certain level, indicating the beginning of a potential issue. At this stage, it's essential to closely monitor the SKF bearing and track its performance changes. Soon after, the kurtosis value starts to drop rapidly, approaching normal levels, while vibration and noise increase significantly. When the vibration exceeds the specification (such as ISO 2372), the kurtosis value also rises quickly. If both vibration and kurtosis exceed their respective thresholds, it indicates that the bearing has entered the late stage of failure and needs immediate replacement. Bearings exhibiting late-stage fault characteristics often show severe issues such as shaft damage, overheating, cracks, raceway wear, or cage damage. These problems can develop within a week, depending on the equipment size and operating speed. Therefore, in practical SKF bearing diagnostics, once late-stage fault features are detected, the bearing should be considered faulty and replaced promptly.
