Hi,
Has anyone ever used thermal imaging to check the condition of linear bearings and their rails and if so, what is the best way to go about it? Any information would be appreciated as I am attempting to draw up a report which would go towards deciding whether it would be advantageous to make thermal imaging a part of our PM system.

Dear Bren
We can help you.The best way to check the condition of linear bearings, is the vibrations control, and analisis (with spectrum).
Please, visit my website, and learn.

What is a linear bearing? Is there any non-linear bearing?
