Abstract: In this paper, we introduce generalized adjoint semigroups (GA-semigroups) of a ring $R$. We construct generalized adjoint semigroups on a ring $R$ by means of bitranslations of $R$. It is shown that GA-semigroups of a $\pi$-regular ring are $\pi$-regular. As an application we deduce that in any ring, idempotents can be lifted modulo $\pi$-regular ideals. GA-semigroups containing idempotents are described in terms of the ring of a Morita context.
