Ƙarfin Centrifugal yana aiki don faɗaɗa zoben riƙewa mai karkace, wanda zai iya sa ta ɗagawa daga cikin tsagi a manyan RPMs. Ana ƙididdige ƙayyadadden saurin ta $N = \sqrt{\frac{4.48 \cdot 10^{12} E t^2}{\gamma D_m^4}}$, inda $t$ shine kaurin kayan kuma $\gamma$ shine yawa. Idan RPM mai aiki ya wuce wannan ƙima, 'ƙuƙwal' zobe a kan tsagi ya ɓace. Don magance wannan, injiniyoyi sun ƙirƙira zoben 'kulle kai', waɗanda ke da ƙaramin shafi wanda ke kulle yadudduka na karkace tare, yana hana haɓakawa. Wannan daidaitaccen ma'auni ne a cikin tarukan turbine na sararin samaniya inda saurin juyawa zai iya wuce 50,000 RPM.
