Abstract

Linear roller bearing, for carriage (1) which is longitudinally displaceable along rail (2). Carriage (1) has an endless channel (8) for endless circulation of rolling bodies (9). Channel (8) has load section (10), return section (11) and two deflection sections (12) which connect load section (10) to return section (11). Rolling bodies (9) roll in load section (10) on raceways (10a, 10b), and returned, without load, in return section (11). Bodies (9) are deflected in deflection sections (12) between load section (10) and return section (11). Deflection sections (12) have one inner deflection means (14) with inner deflection race (16) and outer deflection means (13) with outer deflection race (15). Inner deflection means (14) and outer deflection means (13) are connected, integrally to one another.
