<p>A conveyor roller (10), comprising a covering element (20), an axle element (40), and a magnetic brake (50) having a magnetic component (51 ) and a braking component (54) corresponding to the magnetic component (51 ), the covering element (20) being rotatably supported about an axis of rotation relative to the axle element (40), the magnetic brake (50) being kinematically provided between the axle element (40) and the covering element (20) and being connected to the axle element (40) and the covering element (20) such that a rotation of the covering element (20) about the axis of rotation can be retarded by the magnetic brake (50), wherein the magnetic component (51 ) and the braking component (54) are arranged displaceably relative to each other between a rest position and a braking position, and wherein further 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.</p> |
