A guide roller for web material, in particular for paper-handling machinery, has two outer tube sections (2, 2') and optionally at least one tube section (1) arranged between these. The tube sections (1; 2; 2') are supported on a central shaft (3) through ball bearings (5; 6; 7), and the outer tube sections (2; 2') are adjustable radially relative to the shaft (3) at their outer ends. The ends (1a; 2a) of the tube sections (1, 2) that are adjacent to each other fit into each other and are connected directly to each other so as to non-rotatable, the ball bearing (5) being situated beneath the area of overlap (1a, 2a) and the outer tube sections (2; 2') being configured elastically in the longitudinal direction.
