The invention discloses a novel escalator step roller comprising a roller body and an outer ring. The roller body comprises a first outer circumference and a first inner wall. At least one first groove is formed in the front face of the roller body, and at least one second groove is formed in the reverse side of the roller body. The outer ring is fixedly connected to the first outer circumference of the roller body. The novel escalator step roller has the advantages that lubrication grooves are added to a sliding core, grease can be added to and stored in the lubrication grooves to play a role in long-term lubrication, and bearing rollers used on stairs are replaced, so that good lubrication effect is guaranteed, and the novel escalator step roller is good in wearing performance, corrosion resistance and anti-corrosion performance, low in overall weight and low in cost.
