The invention discloses a novel carrier roller and belongs to the technical field of machinery equipment. The novel carrier roller comprises a shell and a rotary shaft. The two ends of a bearing seat are provided with one-way rotary bearings which are connected with an inner baffle plate. The outer layer of each one-way rotary bearing is provided with a sealing layer which is used as a sealing device. The novel carrier roller is simple in structure and reasonable in design, has the transmission function, designs a backward self-stopping device which can play a self-protection function when a sudden accident occurs, and can prevent safety accidents from occurring.
