Abstract

A guide carriage for a linear roller bearing includes a main body, which may bear in a longitudinally movably manner and via at least a first and at least a second endlessly circulating roller row against a guide rail that extends in a longitudinal direction, a deflection assembly provided on an end face of the main body and including at least one curved inner deflection channel for the first roller row, and at least a second curved outer deflection channel for the second roller row, the inner deflection channel being located within the outer deflection channel, the deflection assembly includes an end cap, on the inner side of which—that faces the main body—an outer boundary surface of the outer deflection channel is provided, and at least one separate, one-pieced deflection piece inserted in the end cap, on which an inner boundary surface is provided that covers the entire outer deflection channel. An outer boundary surface is provided that covers the entire inner deflection channel on the deflection piece.
