Is axial bearing in turbo fan,turbo jet engines neutraly loaded,if yes then turbine/fan and compresor produce eqaul and opposite force?

If yes ,where then thrust come from,at internal walls,must be some pressure net force to produce thrust.

No it generally is not neutral. There is usually some net force. The reason is that very low force is actually bad for bearing life. Look up skidding. So a small imbalance in forces between compressor and turbine is introduced intentionally
