The multiple-row roller bearing (1) for longitudinal guides has a housing (2) with front (V) and back (R) and containing at least two rows of rollers. The housing (2) has a support (3), two ends (4) and at least one guide-strip (42) joined to two plastic end pieces (4). The prismatic support (3) has a track (32) open towards the front side (V) and on the other side, in its back return-part (34), one return duct (35) per roller-row. Each end-piece consists of an inner (41) and an outer (45) part interlocking. The two outer end parts (45) are joined by holder strips (46) to the back and prevent the rollers (5) from falling out of the return ducts (35) open on the back (R) of the support (3). USE/ADVANTAGE - The automatically produced multiple row roller bearing has a prismatic support made externally.
