I have a typical small electric induction motor given to me in pieces. It has two wave washers which I am told should sit between the bearing and the assembly.

I am not sure which bearing needs the wave washers.

  1. Do I place on one wave washer before the front and rear bearings ?
  2. Both wave washers on the rear bearing?
  3. Both wave washers on the front bearing?

Please advise.

I would assume one wave washer for each bearing - this allows pre-load to limit any play and expansion control as it get hot in normal operation.

I intuitively agree with Solar Mike, there should be one washer per bearing. I wanted to find a source/reference, however:

This image appears to show wave washers in front of each bearing motor cross section 1

But this image doesn’t appear to show any wave washers at all:motor cross section 2

So the short answer is: probably 1 washer per bearing, but it will of course depend on the exact motor design. We’ll need more information from you if you want us to comment further.
