I would like the minimum angular clearance in my bearing to be 0.0035 radian after pressing (into 0.062" steel which yields around the OD of the bearing). Please tell me how you need this specified. It looks like I should specify an approximate 30 micrometer internal clearance. Is there a class of fit I should specify?

How does changing the clearances effect the dynamic basic dynamic load rating of the 6006 bearing?

A second question, what would be the cost of an equivalent sealed bearing?
