The effects of uniform rotation on the dynamics, equilibria and stability of cylindrically symmetric, radiating Z-pinch plasmas are studied. Rotation changes the Bennett and Pease--Braginskii equilibria qualitatively, eliminating radiative collapse for both quasisteady and dynamic plasmas. In particular, a steady rotating plasma column can support any current above the Pease--Braginskii value, with Ohmic heating balanced by radiative losses. Stabilizing effect of rotation on the {ital m}=0 mode of Rayleigh--Taylor instability of a hollow plasma shell was found for long perturbation wavelengths. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
