Would you like to tell us about a lower price? At the bottom of this page you will find a list of the recommended vibration standards for turbomachinery compiled from our extensive experience in vibration and damage analyses. As a general rule, machines with rolling-element bearings tend to have high bearing stiffness and are better suited to bearing vibration measurement on the pedestal accelerometers on non-rotating parts.

This part of ISO is not applicable to the following: Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. The evaluation procedures presented in this part of ISO are based on broad-band measurements. If you operate or service turbomachinery you should be aware of the most important standards applicable to your machinery. For large and critical turbomachinery our general recommendation is to have at least one a bearing and a one shaft vibration measurement installed at each bearingsince this covers most adequately both the vibration behaviour in the bearing relative vibration, orbits, shaft centreline… as well as exterior fixed body vibrations component resonances, shaft rubbing, flow effects, gear impacts, looseness, misalignment….

The numerical values specified are not intended to serve as the only basis for Vibration evaluation since, in general, the vibratory condition of a machine is assessed by consideration of both the shaft vibration and the associated structural vibration see the introduction to ISO Conversely, machines with fluid-film bearings on soft pedastals are better suited to shaft vibration measurement proximity probes on rotating parts.
