Abstract
The invention discloses a hard-rolling roller head with two separate housings for deep rolling the outside radii of adjoining crankpins of a split-pin crankshaft. The hard-rolling roller head provides an effective support of the two housings against one another, when machining split-pin crankshafts, and simultaneously prevents the upper areas of these housings from drifting apart.
