Abstract
A linear motion rolling contact bearing assembly includes a rail, a slider subassembly slidably mounted on the rail and provided with an endless circulating path, and a plurality of AF-F rollers provided in the endless circulating path. Each of the AF-F rollers is generally cylindrical in shape and has a flat end surface at one end and a truncated dome-shaped end surface at the opposite end. The endless circulating path includes a pair of straight load and return sections and a pair of curved connecting sections each connecting the corresponding ends of the load and return sections. Preferably, the curved connecting section has a pair of outer guide surfaces each of which has a radius of curvature which is equal to or slightly larger than the radius of curvature defining the dome-shaped portion of each of the rollers.
