This process for manufacturing a hollow roller of a roller bearing includes at least the following steps: machining an outer radial cylindrical surface (S O ), with a circular cross section centered on a first axis (X O ), and machining an inner radial cylindrical surface (S I ) with a circular cross section centered on a second axis (X I ). These two steps are realized on the same lathe (10). The hollow roller (100) is provided with the outer radial cylindrical surface (S O ), with a diameter of at least 5 mm, and the inner radial cylindrical surface (S I ). An offset between the first axis (X O ) and the second axis (X I ), measured in the hollow roller (100) between two axial surfaces of the hollow roller, is less than 2 µm, and an inclination angle between the first axis (X O ) and the second axis (X I ) is less than one minute of angle. The roller bearing (200) comprises amongst others, at least one such roller (100). |
