ABSTRACT:
A snap ring for shafts or bores is proposed, which is able to be axially fixed in position by snapping into place in a circumferential groove. The snap ring is provided with a centering ring which, when the case of the snap ring is installed in the circumferential groove, extends with radial clearance to an annular clip of the snap ring, which is disposed approximately concentrically to the circumferential groove.
