Improving Bearing Reliability in Overhung Fan Applications

This presentation is focused on improving reliability in overhung fan applications. Although the majority of the presentation is aimed at overhung fans, what we’ll discuss is relevant to many different types of rotating equipment, but especially those fitted with plummer block or pillow block bearing housings. The presentation details the common issues we see on overhung fans when analysing data and undertaking reliability surveys at client sites. Unfortunately a high proportion of issues we see stem from poor engineering practices rather than purely mechanical defects and in this presentation we will discuss the common errors.
