The invention provides a practical pulling bottom roller comprising a mandrel and yarn guide rings. The mandrel and the yarn guide rings are designed into an integrated structure, the yarn guide rings are evenly distributed on the outer circle surface of the mandrel, the outer circle surface of each yarn guide ring is of a groove structure which is machined by the rolling technology, the surface of each groove structure is coated with a wear-resistant material so as to form a wear-resistant layer, and the wear-resistant material is nano ceramic powder. The practical pulling bottom roller is reasonable in structure design and outstanding in performance, the groove structures on the circumferential surfaces of the yarn guide rings are convenient to machine, and after the surfaces are coated with wear-resistant coatings, the yarn guide rings have excellent wear resistance and corrosion resistance; meanwhile, the section shape of each groove structure is changed from trapezoid into arc, sudden changes among tooth surfaces are controlled, wear of a roller and occurrence probability of mechanical waves are reduced effectively, and spinning quality is improved.
