Identifying the damage level of SKF imported bearings is a critical process that helps in assessing the bearing’s condition and predicting potential failures. This involves analyzing functional parameters, identifying abnormal conditions, determining the root cause, and evaluating the risk level. It also includes developing solutions for correction and improvement.
Bearing fault diagnosis is not just about detecting or monitoring issues—it requires proper signal collection, data processing, and accurate interpretation—either manually or through automated systems. To determine an effective maintenance schedule, it's essential to understand the mechanisms behind various faults and conduct necessary experiments to estimate the fatigue and wear life of the bearing.
There are three main methods used to assess the condition of SKF bearings:
1. **Listening**: One of the most common techniques is using your ears to detect unusual sounds. Operators often use a screwdriver or an electronic stethoscope to listen for irregular noises. A well-functioning SKF bearing typically produces a low hum. If you hear sharp, uneven, or inconsistent sounds, it may indicate that the bearing is in poor condition and needs immediate attention.
2. **Touch**: Feeling the temperature of the bearing can reveal a lot. High temperatures often signal abnormal operation. Excessive heat can damage the lubricant inside the bearing. If the temperature exceeds 120°C for extended periods, it significantly reduces the bearing's lifespan. Common causes include insufficient lubrication, over-lubrication, contaminants in the lubricant, excessive load, damaged bearings, lack of clearance, or faulty seals. Under normal conditions, a slight temperature rise after lubrication is expected and should stabilize within one to two days.
3. **Visual Inspection**: Checking the bearing’s smoothness and ensuring no debris or moisture has entered is crucial. Inspect the oil seal regularly to ensure it remains intact and prevents harmful substances like hot liquids, corrosive materials, and gases from entering the bearing. If the seal is damaged, replace it immediately. Also, check the lubrication system to ensure the correct amount of oil or grease is being supplied. If the lubricant changes color or becomes black, it indicates contamination, which can negatively affect the bearing’s performance.
