An aircraft actuation system (300) is disclosed that includes a pair of cylinders (322a, 322b), a piston (330) movably disposed in each cylinder, and a roller train (340) that extends between the pistons in the two cylinders. A portion of the roller train is disposed beyond the cylinders to engage a pinion (302). Movement of the pistons in the two cylinders in opposite directions produces a corresponding movement of the roller train to in turn rotate the pinion. The roller train may be maintained in compression between its two ends by fluid pressure exerted on a common face (332) of each of the pistons in the two cylinders. The cylinders may be disposed in non-colinear relation, including in parallel relation to one another. A guide (390) may be used to maintain rollers (350) of the roller train in a proper orientation for entry into a space between an outer race and the pinion.
