Please help to identify component.

[IFixPlanes]

But http://www.b737.org.uk/landinggear.htm shows a 737 NG landing gear.

does anyone have extra information on this part or any internet sites explaning this component..

The term "bogus part" comes up in my mind when i read this kind of question.

But OK.
"Extra information" under http://www.boeing.com/commercial/spares/part_page.html

"explaining" this component:
It connects "shock strut", "drag strut", "side strut" and the inner door with the "uplock roller" who hold the gear up in flight.
