Hi Skatto,
I am working in Ultrasonics at the University of Sheffield. I need more information. What material are you looking through? What resolution do you want? Is it just distance that you are looking at?
The material that you are looking through will have an associated acoustic...
What is the application that you are working with? I am working at the University of Sheffield on a Technique for measuring the oil film thickness in bearings, but also face seals.
Is this any use?
Hi Ulf,
If you want to know whether smearing will take place, measuring the oil film is the critical factor (provided you are measuring in the right place). If you know your oil films, you can redesign/alter the bearing or oil supply to adjust what will happen in the event of an outage.

If you get to the stage of smearing of the babbit, then I suspect you can forget about your bearing lasting very long.
We had a visitor from Lulea the other week, Donald McCarthy, you may know him. He popped in to see our technique running on a journal bearing. Also Sergi Glavatski came to see...
Hi Ulf,
I am working on measuring oil films in a Journal Bearing. We are using an ultrasonic technique, and have sucessfully measured oil films in journal bearings in the lab and on an industrial test rig. The technique is very accurate (we have measured 50nm in a ball bearing), is non...
Do you have the equations that govern the Raimondi and Boyd , charts? I have found the charts in many books, but i need to write an excel spreadsheet that is able to tell me the Sommerfeld number for a given eccentricity and L/D. http://www.tribology-abc.com/software/default.htm has one but the...
