ABSTRACT:
A linear motion rolling contact bearing assembly includes a U-shaped rail of thin steel plate, a U-shaped table of thin steel plate which straddles the rail, a plurality of rolling members interposed between the rail and the table and a retainer for retaining the rolling members in position. Each side wall of the rail is provided with a curved section having oppositely extending slopes on which a pair of upper and lower inner guide surfaces are defined. Each side wall of the table is also provided with a curved surface having a pair of upper and lower outer guide surfaces which are located opposite to the pair of inner guide surfaces of the rail. A first plurality of rolling members are provided as interposed between the upper inner and outer guide surfaces and a second plurality of rolling members are provided as interposed between the lower inner and outer guide surfaces. The retainer plate interposed between the side walls of the rail and the table is so structured to retain those first and second plurality of rolling members in position.
