component disappeared, and vibration returned to acceptable levels. 3. Case Study: Detection of Rolling Element Bearing Failure

The 2X running speed peak in the axial direction was exceptionally high, nearly matching the amplitude of the radial peaks. Practical Case Studies On Vibration Analysis Pdf

As the most critical component in rotating machinery, bearing failures are a primary focus in vibration analysis. Relevant PDFs include: As the most critical component in rotating machinery,

: Outlines steps for implementing a vibration analysis program with experimental results for rolling bearings and gears. Case Studies of Vibrations in Structures Technicians shimmed the motor feet to correct the

A 6316 C3 SKF input bearing on the gearbox had developed severe inner race defects.

Technicians shimmed the motor feet to correct the vertical offset and adjusted the horizontal position using jack bolts. Once tightened to specifications, the pump was restarted. The 2X axial peak completely disappeared, overall vibration dropped to 1.5 mm/s, and the pump operated for over 18 months without a single seal failure.

To document diagnostics professionally, engineering teams use structured verification formats. This template outlines the minimum data required for a formal vibration analysis field report. 1.
