Understanding Bearing Loads - GMN Bearing USA
If your appliion will place an axial load on the bearing, then an angular contact bearing with a higher contact angle around 25 will be a good bearing choice. Just to add some complexity to this, axial loads that are offset from the center of the axis, like a bevel gear, have a “moment force” applied to the inner race.
