Abstract: A roller for a control surface of an aircraft includes a roller shaft, a primary roller coupled to the shaft, and a roller assembly coupled to the shaft. The shaft includes a longitudinal axis, a mounting end that couples with a roller fitting of the control surface, and a roller end. The primary roller can rotate about the longitudinal axis, and can engage and roll along a first surface of a track. The roller assembly includes a secondary roller having a longitudinal roller axis and configured to engage and roll along a second surface of the track. The roller assembly also includes a housing that retains the secondary roller while allowing the secondary roller to rotate about the longitudinal roller axis. The housing is movably coupled to the roller end of the roller shaft with three degrees of rotational freedom relative to the roller end of the roller shaft.
