An aircraft armrest may incorporate a rail roller linkage. The roller linkage may include an armrest plate, a rail attached to an aircraft seat assembly, a top roller link, and a bottom roller link. The top roller link may have a threaded upper adjustment cylinder, a pivot joint, and a pair of grooved rollers diagonally disposed on either side of the pivot. The bottom roller link may have an unthreaded lower adjustment cylinder, a pivot joint, and a pair of grooved rollers diagonally disposed on either side of the pivot. The grooved rollers may mesh with the rail. The roller linkage may include a roller adjustment screw, having a threaded portion, and extending through both of the adjustment cylinders. A compression spring may bias the roller link around the rail and may be disposed between the top roller link and the bottom roller link and surrounding the roller adjustment screw.
