Do these bearings fit all idler pulleys?

Hello I read the previous thread I just want to make sure these bushings arent pulley specific and will fit into the 3 idler pulleys?

Thank you

i would assume so. Unfortunately last i knew of he no longer has the puilley bearings. Pretty hard to find. As well as by the time you get them and pressed in the entire cost of a NEW pulley itself is within reach...

I found some on ebay hoping they wont be too annoying to press in.

Hope they are not so cheap they fail quickly. Nissan uses top level bearings.
