Paragraph 2, in post #2 above pertains no matter how you ask/rephrase the question.
A raceway is actually parabolic in shape. The sides are "flattened" out a bit and they acually get rolled over so there is not a sharp edge where raceway intersects the ring ID. The profile on the sides is not controlled as exactly or as well as the "crotch" where the ball is supposed to ride.
This is why shock applied axial load is something that you simply can't design for nor predict the performance of when it comes to deep groove ball bearings. Empirical wisdom is best served here.
Try it and see is the best I can offer in the way of guidance. |
