What is the clearance ratio between the plain bearing and the shaft?
You have to know exactly what kind of industry, as well as load, speed and other parameters, so that after reading to you to provide samples of the bearing manufacturerCan be calculated, the fastest way is to contact the bearing factory directly, so that they give you to calculate your axis should do what tolerance
I don't think so. I do rolling bearings, I'm sorry
You have to make sure you use the sliding bearing in what occasions, and then open the "mechanical design manual" volume second, find the bearing this post, there is the bearing and shaft in different occasions with the axis of tolerance, then as long as the "mechanical design manual" the first volume to check the corresponding numerical OK. It's simple
