One of the main reasons Indramat servo motors run reliably for 30+ years is the quality and design of the bearings. Indramat servos are equipped with lifetime lubricated bearings that provide constant performance with practically no maintenance. But just how long do lifetime bearings last?
How long is a lifetime?
This question isn’t as easy to answer as you might think. A lifetime lasts a lifetime, right? It’s obvious. However, lifetimes vary considerably.
Life expectancy varies across the globe. The average life expectancy in Cameroon is 50 years, whereas the average life expectancy in Japan is 75. A quarter of a century is a significant difference.
And that’s just the lifetime of people. A person has a longer lifetime than a car, which has a longer lifetime than a dog, which has a longer lifetime than a pair of running shoes, which has a longer lifetime than a banana, which has a longer lifetime than a mayfly… You get the idea.
Then, of course, each shoe or banana or mayfly can live longer or less time than another shoe, banana, or mayfly.
In other words, saying that something lasts a lifetime is like saying something lasts until it doesn’t. That is, it’s a little vague.
How long do lifetime lubricated bearings last?
Obviously, the lifetime lubricated bearings in Indramat servos last a long time. The lifetime of those bearings isn’t based on your lifetime, however.
Lifetime lubricated bearings last the lifetime of your servo motor under normal conditions and appropriate use.
People sometimes forget that lifetime doesn’t mean forever. Even if your bearings are holding up, you may need maintenance or maybe even a remanufacture on your Indramat products from time to time.
