ABSTRACT:
A linear motion rolling contact bearing assembly including a rail, a slider and a plurality of rolling members interposed between the rail and the slider for providing a rolling contact therebetween is provided. The rail includes a bottom wall and a pair of side walls extending upward from the opposite sides of the bottom wall, so that the rail has a U-shaped cross section. The slider includes a frame which is comprised of a top wall and a pair of side walls depending from the opposite sides of the top wall, so that the frame has a U-shaped cross section. Each of the side walls is provided with a guide groove so that the rolling members are interposed between the rail and the slider as partly fitted in a pair of associated guide grooves. The rail is provided with a stopper at each end thereof, and the side walls of the frame extend sufficiently downward so that their bottom ends are engageable with the stopper when the slider has moved to an extreme end of the rail, so that the slider is prevented from slipping away from the rail.
