A conveyor roller (10) has a cover (20), an axle (40), and a magnetic brake (50) having a magnetic component (51) and a braking component (54). The cover (20) is supported rotatably about an axis of rotation relative to the axle (40). The magnetic brake (50) is provided kinematically between the axle (40) and the cover (20) and is connected to the axle (40) and the cover (20) so that rotation of the cover (20) about the axis of rotation can be retarded by the magnetic brake (50). The magnetic component (51) and the braking component (54) are arranged displaceably relative to each other between a rest position and a braking position. A centrifugal device (60) for a rotational speed-dependent displacement of at least one of the magnetic brake components (51, 54) is provided between the rest position and the braking position.
