Abstract
A linear motion rolling contact bearing assembly includes a trough-shaped bed, a trough-shaped table which straddles the bed, a plurality of balls interposed between the table and the bed for providing a relative motion between the table and the bed along the longitudinal direction of the assembly, and a retainer for retaining the balls in position. The retainer includes an elongated plate provided with a plurality of holding holes for holding the balls in position and at least one side projection which projects sideways from the plate so as to maintain the retainer in its intended position. Preferably, the top and bottom side projections are provided on both sides of the plate so that the retainer has an I-shaped cross section. The retainer is also preferably provided with one or more tabs provided around each of the holding holes so as to securely hold the balls in position. The side projections may be provided also in the form of a plurality of dots.
