Using vibration analysis to evaluate machine health has many benefits, and with advances in sensor, recording, and analysis technology, vibration analysis is now within the reach of even small organizations.
A Chicago-area bakery was replacing
the tray support bearings in its ovens
on a reactionary basis. Their weekly
inspection cycle was resulting in two
mechanics spending an average of 20
labor hours per week to replace failed
bearings. The premature bearing failures
were caused by a combination of
the high heat and humidity in the ovens,
resulting in lubrication failure and
contamination. When BDI was asked
to recommend a solution, the bakery
was averaging one month of bearing
life in this application.
I was invited by Tom Astrene of TLT to write a response to the
July 2010 TLT article (Ref. 1). My rebuttal — “In Search of a Fatigue
Limit: A Critique of ISO Standard 281:2007” — was published
in Tribology and Lubrication Engineering, TLT, August
2010 edition (Ref. 10). While this article is also available online,
I will attempt to summarize the essence of my response.
Richard (RJ) Seguin, CBS and technical
sales representative at AMI Bearings,
explains how his bearing expertise tripled
the life of a customer’s bearings.
