The invention relates to a radial rolling bearing which is designed as a clamp-ring bearing and in which the inner race can be fixed in a defined position on the associated shaft by means of a clamping ring by way of eccentric, mutually corresponding ring extensions. The essential point of the invention is the proposal, for the purpose of safeguarding against axial displacement and radial detachment, additionally to brace the two eccentric ring extensions (2', 5') against one another by means of at least one retaining screw (7). <IMAGE>
