machine vibration specification

A Brief Tutorial on Machine Vibration

Table 1 is a general guide for acceptable vibration on many classes of common machines. This table was compiled from industry standards, some published specifications, from manufacturers’ factory balance levels on new equipment, and from field experience. These limits apply for measurements at, or as close as safely possible to, the bearings.
