Abstract

A component having a split running face for rolling elements, running face being disposed partially on a bearing cap, and a method of producing the same. According to the method, a preform is made from a material having a carbon content of at least 0.5 percent by weight; the preform is separated by fracture separation at a separation location of the preform thereby producing the bearing cap and a remainder; skin layer hardening is performed on the running face thereby producing a skin hardened layer such that the running face acquires a Rockwell hardness of 55 according to the Rockwell cone method.
