Kubara ubushobozi ntarengwa bwemewe bwo gusunika impeta igumana impeta ukurikije imbaraga zo gukata ibintu byimpeta.

Ubushobozi bwo gusunika bushingiye ku mpeta y'impeta $ P_r $ ibarwa ukoresheje formula $ P_r = \ frac {D \ cdot T \ cdot \ pi \ cdot S_s} {S_f} $, aho $ D $ ni diameter ya shaft / bore, $ T $ nubunini bwimpeta, $ S_s $ ni imbaraga zogukoresha ibikoresho (hafi 0.6 $). Iyi mibare ifata ko igikonjo cyimbitse kandi ibikoresho bya groove birakomeye bihagije kugirango birinde impeta kuroba. Niba ibikoresho bya groove bitanga umusaruro mbere yimpeta zogosha, ubushobozi bugarukira kumasoko yumusaruro wa groove $ P_g = \ frac {D \ cdot d \ cdot \ pi \ cdot S_y} {S_f} $, aho $ d $ nuburebure bwimbuto naho $ S_y $ nimbaraga zumusaruro wibikoresho bya groove.
