An assembly includes a first component joined to a second component by an intermediate joint. The first component has a first joining surface arranged coaxially and spaced in a juxtaposition around a second joining surface of the second component such that a groove is defined between the first and second joining surfaces. One of the first and second joining surfaces includes a concave portion and the other of the first and second joining surfaces has a convex portion radially opposite the concave portion, and the groove is formed by the convex and concave portions. The intermediate joint is formed by an insert ring pressed into the groove and deformed such that material of the insert ring fills the concave portion and surrounds the convex portion, and this locks the first and second components relative to each other in both axial directions.
