ABSTRACT:
A linear roller bearing is provided having a guide carriage (1) which can be mounted on a guide rail (2) in a rolling manner via roller bodies (4). The guide carriage is provided with at least one continuous roller body channel (3) for the roller bodies (4). The roller body channel (3) includes a support channel (5) for supporting the roller bodies (4), a return channel (11) for returning the roller bodies (4), and deflecting channels (10) which connect the support channel (5) to the return channel (11). The deflecting channels (10) are provided in end elements (9) of the guide carriage (1), and the roller bodies (4) in the roller body channel (3) are subject to displacement resistance in the direction of rotation. The end elements (9) are respectively provided with a sensor (12), whereby a preferably electric sensor signal therefrom is dependent on the displacement resistance.
