DESIGN FACTORS WHEN USING SMALL BEARINGS, PART 1: BEARING GEOMETRY (Page 3)


Once the preload has been applied, the balls will sit at the ball contact angle. This angle will increase as more preload is applied, and the starting value of this angle (the initial contact angle) will be larger for larger radial play values.

The axial displacement of the raceways relative to each other under load is the axial play. It is typically 8-10 times the radial play for a given bearing and so must be acccounted for in any design.
