Hi I am new to Ansys and moslty i learn by research paper having steps of simulation and youtube videos but i am stuck in a simulation,
i have to do structural analysis of decoiler(used in rolling machines), i gave bearing connection and used formula by Gargiulo, E.P.,Jr., A Simple Way to Estimate Bearing Stiffness, Machine Design, 1980, pp.107-110.to calculate stiffness for bearing.

The whole structure is machine body as in attached image, the pblm is that i am confused about contacts that i need to define further so that bearing will transfer load to machine body, say if i place 5 tonne coil on shaft, i am able to do it in solidwork sim but ansys is giving of excessive displacement.
