What can anyone help me, how to model the bending on solidworks, a pipe with two shafts on each side with bearing and discs (4 discs) inside the pipe, to hold the shafts in the pipe (see image)

Hi all 

My project  is to model an industrial garage door  on solidworks to  evaluate the resistance to the wind load , at the level of the garage curtain made of rubber , but first I wanted to  check the resistance of the main unit (see attached image ), in order to model the bending  of this sub-assembly composed of: pipe  , shafts,  discs and bearing (bearing), 

Kind regards

and thank you  in advance

Ps: how to make the connections and which ones?   also what are the fixed geometries that I have to impose
