The roller bearing comprises a roller cage assembled between a pair of guide rails. The roller cage is formed with a plurality of roller pocket openings of a predetermined shape spaced with a longitudinal distance, each of the openings defining two pairs of roller holding pieces of the same shape, one of the roller holding piece pairs being turned in one direction and the other being turned in the opposite direction to form a roller pocket for receiving a roller in an inclined position between the roller holding piece pairs such that rollers received in every other pockets cross at right angles with rollers in the other roller pockets.
