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.
Here’s what we know about Tremont, Illinois: It’s a small village in Tazewell County, (population 2,400+), holds an annual summer turkey festival
(quite popular) and the courthouse is a famous historic site where politician James Shields challenged an “up-and-coming” lawyer named Abraham Lincoln to a duel with cavalry broad swords (they showed up, but the duel never materialized). In 2016, you can add FIRST Robotics Competition World Champion to the village’s rather eccentric list of accomplishments.
Increasing pressure on many fronts is compelling mine operators to thoroughly examine every phase of their operations. Fluctuating demand
that whipsaws mineral prices, government-imposed environmental regulations and rising operating costs related to maintenance downtime all pose serious challenges for the mining sector. Add pressure from customers and stakeholders for more sustainable operations as well as union demands for higher wages, and you have a scenario that requires mine operators to exercise every possible option to
achieve more efficient operations.
Rolling-element bearings are high-precision components that need to be stored and handled carefully to perform as designed. Proper storage and
handling of a bearing before, during
and after installation is important because once debris enters a bearing, it
reduces the life.
In this century’s complex, ever-
changing world of manufacturing,
such capabilities as hardware and software expertise, effective location and distribution, business savvy and
yes, even luck, are some of the
cardinal requirements for running
a successful business.
