The assembly has a metallic annular ring defining a reference geometric axis and an annular radial face on which a conveyor track (28) is formed. A cap (40) closes a radial bore (34), where the bore has an internal section for passing an inscribed ball from exterior of the ring to the face. The cap has a base with a groove (50) having an axial width lower than diameter of an interior section of the bore. The cap is radially recessed with respect to the face, and is made of steel. A joint (45) is disposed between the cap and the bore. |
