Roller-shaped elements are disposed between races formed on the parts to be guided relative to one another. Each of these rolling elements has two spaced, spherical-segment-shaped bearing surfaces which are in substantially point-wise contact with the races. This design makes it possible to accommodate more rolling elements circumferentially as compared with constructions utilizing balls as the rolling elements, thus increasing the bearing capacity and rigidity of the guide means while maintaining low-friction rolling conditions.
