What is the large diameter shaft like tube running from the rear of the fan case nearer to engine centerline, disappearing into fan exit vane area, to the top of the turbine section on a GE90 engine? This item has 2 roller looking components mounted on it's end where it ends at the turbine. This tube is the largest straight piece outside the case. Looks to make an angle to centerline both horizontally and vertically.

They are thrust struts, the roller links you mentioned slot into receptacles on the cowls to ensure they are aligned correctly when closed.
