Abstract: A cone crusher head, system, and crusher including the cone crusher head and system. A conical mantle radially extends from an interference fit section and has a head diameter Dch. The conical mantle has a wear part support surface and a shaft support surface. The interference fit section has a nominal interference fit diameter Dif. The conical mantle has an armpit groove for receiving a slip ring. The armpit groove is covered by the conical mantle with an armpit thickness La. Fretting wear is reduced by dimensioning the crusher head so that a ratio of the head diameter Dch to the nominal interference fit diameter Dif is most 2.5; and a ratio of the head diameter Dch to the armpit thickness La is at least 10.5.
