Abstract
A striking tool for crushing metal or stone materials, where the striking tool is manufactured from an iron-based material and includes a bearing section, into which a bearing opening is formed around a pivot axis and includes a striking section which is exposed to a striking load by contact with the material to be crushed, and a rotor equipped therewith for a machine to crush metal or stone materials. The striking tool improves with the ability of its bearing section to absorb the dynamic loads acting on the striking tool. The bearing opening has a support section, on whose inner circumferential surface the striking tool is mounted for its swing movement around the pivot axis and has an extension section, which is connected to the support section and the bearing opening is extended in the direction of the striking section with respect to the support section.
