Vibration monitoring has always been a part
of industrial maintenance, but formanufacturers relying on servo motors, linear transport systems and high-speed automation, it’s about more than just avoiding mechanical failure. Excessive vibration can interfere with positioning accuracy, reduce machine lifespan and disrupt synchronised motion. ISO 20816 builds on ISO 10816, refining how vibration levels are classified and assessed. The
new standard doesn’t change the fundamental principles of vibration analysis, but it does introduce more specific criteria for different types of machinery, recognising that a high- speed servo-driven transport system doesn’t behave like a centrifugal pump or a gearbox. For manufacturers operating servo-based
automation, it provides a more relevant framework for condition monitoring, helping to catch performance drift before it leads to system-wide inefficiencies.
One of the key differences in ISO 20816 is its recognition that different types of machines experience vibration in different ways. Traditional vibration monitoring typically focusses on rotatingmachines, with thresholds based on motor speed, housing vibrations and bearing conditions. Linear motion systems, servo actuators and direct-drive automation systems don’t fit neatly into that model. By refining measurement locations,
frequency ranges and vibration thresholds, ISO 20816 enables more accurate assessments of vibration in systems where linear guides, ball screws and actuators are critical.
Instead of relying on generic vibration limits, manufacturers can now monitor the components that actually affect precision and longevity in their specific type of machinery. For example, in high-speed electronics
assembly, even minor vibration inconsistencies can throw off alignment, leading to higher defect rates. In automated product transport, unwanted vibration in conveyor belts or rail-mounted systems can cause positioning errors and excessive wear. ISO 20816 provides a more structured way to evaluate vibration in these systems, helping manufacturers set meaningful limits rather than relying on one-size-fits-all guidelines.
The introduction of ISO 20816 doesn’t mean that ISO 10816 was ineffective, it just reflects how industrial machinery has evolved. As automation systems have become faster, more precise and more data-driven, the need for more specific vibration criteria has grown. This new standard aligns vibration monitoring with modern manufacturing methods, giving engineers a better framework for assessing performance and preventing faults. Formanufacturers looking to integrate ISO
20816-compliant condition monitoring into their automation systems, Beckhoff UK offers tools that make real-time assessment seamless.
