A splined rail system comprising: a lead screw for rotation about a rotational axis; an internally splined guide rail defining a mouth and an internal cavity in which the lead screw extends, the guide rail including a plurality of guide teeth extending longitudinally and generally parallel to the rotational axis, being angularly spaced apart, and extending radially inward; a nut attached to the lead screw positioned within the internal cavity, the nut including a plurality of guide teeth extending radially outward, and being angularly spaced apart, the guide teeth mating with the guide teeth of the guide rail; a seal substantially sealing the mouth of the guide rail, the first portion extending through the seal and being exposed externally of the internal cavity; and wherein the seal includes a pair of seal flaps extending towards one another, each flap having a distal end, the distal ends abutting one another to form a seal interface therebetween such that the seal prevents debris from entering the guide rail radially through the mouth.
