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.
James Sylvester is an RMS Trainer at the Reliability Training Institute.
RMS has been a key Mobius Training partner since 2004 and James’ addition to the team will help us in delivery of the growing number of course offerings available. James will support in the delivery of our Accredited training courses conforming with ISO 18436, that offer either MiBoc or BINDT certification options.
James is a time-served engineer with more than 20 years’ experience in the implementation of Condition-Based Maintenance and Reliability-Based Maintenance programs, with practical experience and qualifications make him an ideal candidate for the role as an RMS Trainer.
Starting as an apprentice fitter turner (millwright) and after 10 years in the Mechanical Engineering and Maintenance James made the move into Condition Monitoring and Reliability Engineering. He has spent the last 20 years working with many of the Blue-Chip companies in the UK and Australia.
James is the Author of Enhanced System Reliability Through Vibration Technology and Book of Gold, Practical Condition Monitoring Case Studies.
