What is the name of the small pins that are used with small wheels / rims?

Question

I see that there are at least three different types of axles that can be used with LEGO wheels. I can name the first two — Technic axle and Technic pin — but I cannot name the third, which is like a Technic pin, but smaller.

Note that I've only seen it integrated into a larger part, such as a brick or plate, as shown in the image. I see that BrinkLink sometimes refers to parts like this as having "wheels holder" pins, but that seems to be a term that could apply to the first two types of axles as well.

Does a common and more precise name exist for this type of pin?

LEGO and others sometimes calls those pieces a "bearing element". This term however is not limited to just that axle.

LEGO's replacement parts service calls the holes they go into "HOLE Ø11" (possibly read "Hole Diameter 11"):

The width of the axle is roughly equivalent to the width of a "bar", like the 30374 piece used for Lightsabers as such.

None of these names are particularly satisfactory, but I'm not aware of any better names.

Thanks. Is "Ø" a way of writing zero, or does it mean something else? – EJ Mak Oct 05 '17 at 22:09

See https://bricks.stackexchange.com/questions/8060/%C3%98-in-lego-part-names?rq=1 for an explanation on the diameter symbol. – Phil B. Oct 05 '17 at 22:37
And is "W" an abbreviation for the word "with?" – EJ Mak Oct 06 '17 at 14:50
@EJMak I assume so, yes. – Alexander O'Mara Oct 06 '17 at 15:44
