Does anyone have a general rules of thumb they follow on acceptable DN numbers, especially with high speed apps? I'm talking VERY general rules, nothing too specific.

Thanks.

Dear sir--- DN is bore in mm times RPM. It is a (crude) measure of the speed sendsitivity of a bearing application. A DN of > 1E6 is considered high speed and the application merits special attention to alignement, lubrication, etc.
