摘要

The cage for rollers in linear drives is made up of square frames which fit between the rollers and are linked along the outer edges of their sides by longitudinal bars (30). There are recesses (50) at the corners where the uprights (40) meet the cross-bars (60) of the frames. The bars of the frame have a square cross-section and the cross-bars press against the rollers.
