Dynamic Vibration Absorber

This is the 6th, and bonus video case study from the book ‘Enhanced System Reliability Through Vibration Technology’ (ESRTVT) by James Sylvester. In this video James covers a 2-year project period from initial root cause diagnosis on a dynamic vibration absorber to designing, trialing, and implementing an innovative cost-effective solution.

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.

Vibrating Screen Gearbox Bearing Defect

This is the fourth of five video case studies from the book ‘Enhanced System Reliability Through Vibration Technology’ (ESRTVT) by James Sylvester. In this video James shows how it’s possible to diagnose faults on a vibrating screen gearbox. By measuring the correct vibration parameters you can resolve defects in harsh applications, even an inner raceway defect on a vibrating screen.

Standby Fan Motor Bearing Defect

This is the second of five video case studies from the book ‘Enhanced System Reliability Through Vibration Technology’ (ESRTVT) by James Sylvester. In this video James shows how analysing bearing damage on a fan motor bearing can lead to the root cause of the problem. Read more


Electrical Vibration Problem

This is the first of five video case studies from the book ‘Enhanced System Reliability Through Vibration Technology’ (ESRTVT) by James Sylvester. In this video James shows how vibration analysis can be used to diagnose electrical vibration problems on a VFD driven Motor. Read more
