Isn't people often the most important thing? Well, the same goes for bearings. The foundation of a bearing's performance lies in its quality. SKF bearings are manufactured under strict control of bearing steel and cross-roller technology, ensuring that their quality is among the best in the industry. But why do some bearings still fail or show signs of damage? This is usually due to improper usage rather than the bearing's own quality. Faults in bearings can arise from various factors, including incorrect installation, poor maintenance, or environmental conditions. Bearing fault diagnosis isn’t just about detecting a problem—it’s a comprehensive process that involves analyzing performance parameters, predicting reliability, identifying the source and severity of issues, and determining the best repair or improvement strategies. This requires accurate signal acquisition, efficient data processing, and either manual or automated analysis. To establish an optimal maintenance schedule, it's essential to conduct tests and estimate fatigue and wear life based on the failure mechanisms involved. 1. Shaft Tolerance and Bearing Housing Selection: SKF bearings are not flexible once they are mounted. If there is excessive tightness or difficulty in rotation, it could indicate that the shaft size is too large or the tolerance is not properly controlled. If you feel resistance while turning the shaft after installation, it may be due to an oversized shaft or poor tolerance. Proper control of both the shaft and bearing tolerances, as well as roundness, is crucial for smooth operation. 2. Bearing Assembly Method: Since SKF bearings are high-precision components, improper assembly can easily cause damage to the raceways, leading to premature failure. During installation, a special mold should be used, and direct hammering should be avoided. Only light pressure should be applied to the inner ring, and the outer ring should be pressed evenly. The use of air or hydraulic pressure during assembly is recommended, and care must be taken to avoid misalignment, which can damage the crossed roller bearings and affect their performance. 3. Preventing Foreign Object Contamination: When installing bearings, it's important to ensure that the rotor is dynamically balanced before assembly. Any metal shavings or debris left inside can negatively impact the bearing’s performance. SKF bearings are often pre-lubricated with oil or grease, but controlling the amount can be challenging for operators. If excess lubricant remains in the housing, it can migrate along the shaft into the bearing itself. It's better to avoid over-greasing the bearing housing unless necessary, and if no lubrication is applied, ensure that no foreign material is left inside. 4. Preventing Paint Rust: Paint rust is a common issue in sealed motors. Even if the motor runs smoothly during assembly, it may develop unusual noises after being stored for a while. Bearings may become severely corroded due to moisture and volatile acids from insulating paint. This can lead to corrosion of the raceway surfaces. The solution is to choose high-quality paint and allow the motor to air dry after assembly to reduce the risk of corrosion. 5. The lifespan of a bearing is closely tied to its manufacturing, assembly, and usage. Each stage must be carefully managed to ensure that the bearings operate at their best, thereby extending the service life of the crossed roller bearings. By maintaining high standards throughout the entire process, you can significantly improve the reliability and longevity of your bearings.
