Is a fan bearing or bushing?

is it this one?

-Lasse

If it doesn't say otherwise, it's most likely bushing.

It is either 2 ball bearings or one ball bearing and one bushing. Which is which is not specified on the sheet.

Take it to bits and have a look, of course.

The detail will be in the manufacturer's datasheet associated with the exact part number.

Yes, it's on that data sheet. Ball bearings then.

Most bearing types will act as a spring when you push in on the impeller.

I'll repeat, most fans I have come across have a spring loaded bearing. I don't trust that to tell motor specs, but I am just saying fact.

Actually I don't belive they do ! The magnetic field causes the rotor to float.

Most that I've seen say "ball bearing" right on the label if they are, since it's a selling point.

inch,

I see what you mean. There's a missing zero after the EFB. I can't imagine many manufacturers having part numbers that close that were quite different though.

I assume your introduction of the leter 'P' is also a typo.

Usually, when it's ball bearings it's a sign of quality to the end user so it usually is marked "ball bearings." (Of course it could still be a mix with one end a bushing and the other end a ball bearing.)

I was 'on the ball' at the time < groan > ;~)

inch,

P could indicate sintered phosphor bronze bushing while B indicates ball-bearing :)
