A novel roller for a roller cage comprises an elastic layer and a metal wheel, wherein the elastic layer is connected to the outer side surface of the metal wheel; the elastic layer comprises a wear layer, a buffer layer and a body layer from the outside in; and the body layer is connected with the metal wheel in an integrally casting manner. According to the novel roller for the roller cage, the elastic layer adopts a three-layer structure, so that the roller is not only wear-resistant but also high in vibration resistant, and long in service life, and can achieve the optimal shock-proof and wear-resistant effects.
