A Balanced Approach to Acceleration and Velocity Monitoring

This article discusses the characteristic differences between acceleration and velocity monitoring. It is essentially written for the purpose to gain a practical and intuitive sense of the differences between acceleration and velocity monitoring by...

Frequency Calculator

In order to support the frequency spectrum analysis, this program provides the typical frequencies of rotating machinery components.

Frequently asked questions about enveloping, using an accelerometer transducer

Acceleration enveloping is widely used to detect problems associated with bearings and gears. This documents addresses some of the questions that are frequently asked of SKF support staff.

Improved Maintenance Reliability

This paper is written in response to a number of Reliability and Condition Monitoring Engineers. Often the questions that are asked point toward a requirement to understand both the current and the new practices available to Reliability Engineers that...

Integration of Vibration Signals

Integration results from the physical and mathematical relationship between acceleration, velocity, and displacement units of measure for machinery vibration. Here we outline the case for and against

Introduction Guide to Vibration Monitoring

This guide introduces machinery maintenance workers to condition monitoring analysis methods used to detect and analyze machine component failures. This guide does not intend to make the reader an analysis expert. It merely informs the reader about...

Low Speed Analysis

This article discusses vibration monitoring of low-rotational speed machines, setup considerations for the vibration analysis, and types of noise related to signals and cabling. Also included are various examples and vibration analysis solutions for...

Measuring with different SKF devices

This article discusses the possible reasons for variations in vibration measurements when using different SKF portable devices. It contains a table to help equate the variation to Microlog readings.

Multiparameter vibration analysis of various defective stages of mechanical components

This paper presents the multiparameter vibration analysis approach (by means of two case studies), highlighting its importance in the daily predictive maintenance activity of vibration diagnosis of an asset’s health.

This application note presents a set of guidelines for initially establishing Alert and Danger alarm thresholds for enveloped acceleration measurements for early detection of rolling element bearing damage.
