A roller (3; 3′) has a stationary rod (40) arranged along a longitudinal axis (L) and a tubular roller shell (10) arranged around the rod (40). At least one bearing assembly (20; 20′) is arranged on the rod (40) so that the roller shell (10) can rotate about the longitudinal axis (L) of the roller (3; 3′). An internal assembly (30; 30′) is on the rod (40) within the roller shell (10) and is coupled to the roller shell (10) via the bearing assembly (20; 20′). Thus, upon rotation of the roller shell (10), an exchange of force occurs between the internal assembly (30; 30′) and the roller shell (10). The internal assembly (30; 30′) is coupled to the bearing assembly (20; 20′) by an end (31) that faces the bearing assembly (20; 20′) so that the internal assembly (30; 30′) can tilt relative to the bearing assembly (20; 20′).
