Stresses concentration in loaded shaft with bearing

Hello, I've been trying to get the stresses of a shaft with disc brake loaded with torques and radial force.

I added a Bearing fixtures to two faces where real bearing are supposed, all the loads and torques and one more bearing to the down with "stabilize shaft rotation" option checked.

The results seems reasonable except I got stress "stripes" right on the edges of the bearing surface and it just keeps increasing with smaller mesh.

Does anybody run on this kind of problem? How to get rid of this concentration?
Best regards,

Anton
