Glossary

Vibrations refer to periodic movements or oscillations in a system, which can be caused by external forces, imbalances, or structural irregularities.

• Question: What impact do vibrations have on rolling bearings?
  • Answer: Vibrations can affect the performance and lifespan of rolling bearings if not controlled or minimized.

• Question: What are tolerance classes in relation to vibrations?
  • Answer: These tolerance classes, also known as vibration classes, are used to define acceptable vibration levels for specific applications. They help ensure that vibrations during operation stay within defined limits to ensure optimal performance and reliability.

• Question: How are vibrations measured and monitored in rolling bearings?
  • Answer: The measurement of vibrations, also known as Operational Behavior Analysis (OBA) or Condition Monitoring, involves monitoring vibration patterns and levels to indicate potential problems and prevent premature failures. This enables early intervention and maintenance to extend the lifespan of the bearings and minimize downtime. Kugellager Express utilizes Bearing Vibration Testing (BVT) rigs to measure vibrations in ball bearings.

• Question: What types of vibrations are there?
  • Answer: In terms of rolling bearings, vibrations can take various forms, including axial vibrations, radial vibrations, and moment tilting vibrations. These vibrations can be caused by imbalances, operating conditions, or structural issues and must be monitored and corrected if necessary to ensure optimal performance of the bearings.
