Surface finish on metal vs plastic

[Kinsrow]

Would it safe to say that surface finish of 16 microinches on plastic have the same characteristic as 16 microinches on metal?

I'm making a custom machined Delrin bearing that would slide to aluminum. As Machined surface is pretty rough on both bearing surfaces. What would be the normal plastic surface finish for bearing application ( assume using hard steel).

Thanks
