Mashiinnada beeraha sida cagaf-cagafyada ama makiinadaha saxanka ayaa had iyo jeer isticmaala geerka bevel, qaarna geerka bevel-ka ee wareegsan ayaa la isticmaalay, qaarna geerka bevel-ka ee toosan ayaa la isticmaalay, qaarna geerka bevel-ka ee laambadaha ayaa la isticmaalay qaarna waxay u baahdeen geerka bevel-ka ee saxnaanta sare leh. Si kastaba ha ahaatee, inta badan geerka bevel-ka ee loo isticmaalo mashiinnada beeraha waxaa lagu sameeyay geerka bevel-ka ee laambadaha leh, saxnaantu waa DIN8. Si kastaba ha ahaatee, badanaa waxaan isticmaali jirnay bir yar oo kartoon ah si aan u sameyno carburising si aan u daboolno adkeysiga dusha sare iyo ilkaha ee 58-62HRC si loo hagaajiyo nolosha qalabka.
