  • Bearing Tolerances & Precision Class - Bearings Direct

    An interesting analogy and discussion about bearing precision classes vs. running capabilities is the 1-10 analogy. Every bearing actually has the same theoretical maximum RPM. A 6005TBR12P4 (ABEC7) bearing in precision ABEC 7, ABEC 5, or even ABEC 3 would all have the same theoretical maximum RPM rating. What changes is the opportunity to ...
