Hi Gabriele, this is an online calculator I like to use.

I put your data in but you did not specify the Line Contact length. If I use 10 mm it calculates a maximum Hertizan contact pressure as 328.4 MPa. If I use 1 mm it calculates a pressure of 1038.5 MPa.

It looks like you have created a 2D analysis. Did you choose Plane Stress or Plane Strain?  Plane strain is calculated based on a unit depth, so if you are working in mm, then the Plane Strain contact pressure is expected to be the 1038.5 MPa result.
