What is machine vibration?

30-Second Summary

  • Wear and tear, Unbalance, looseness and misalignment are the most commonly found vibration issues in machines.
  • Precision balancing and alignment practices will help minimise forces acting on a machine’s bearings and shaft seals, thereby resulting in improved reliability of these key component parts
  • Timely detection of vibration can help avoid downtime and enhance the lifespan of machines.

Four-point Contact Bearing – 23RPM Defect

This would have been the final of five video case studies from the book ‘Enhanced System Reliability Through Vibration Technology’ (ESRTVT) by James Sylvester; but James added a sixth, as a bonus! In this video James demonstrates vibration analysis of a slow rotational Four-point Contact Bearing, with a 23RPM Defect. This is to remind us that correct database set up, and Time Waveform Analysis is so important in slow rotational bearings.

30-Second Summary

  • Understanding the machine, getting early warning of faults, detection of all fault conditions, and repeatable measurements are crucial for effective vibration analysis.
  • Vibration analyst courses that are compliant with courses that follow the ISO 18436 standard are quintessential in the present-day scenario.
  • An efficient vibration analyst must take quick and economical measurements, and aim to detect the most common faults before the failure of the machine.
