An element for radial guiding of a pivot of a rod of a rotating wheel, for example a rod of a balance, for a bearing of an horological movement, in particular shock-absorbing, the guide element including a body configured to cooperate with a bearing unit in such a way as to be maintained in the unit, the body defining a space for radial retention of the pivot, to maintain the rod radially while allowing it to rotate. The radial guide element includes at least three localized radial-bearing parts distributed angularly, the three parts defining the radial retention space, each part having a face for contact with the pivot, each face locally having a cylindrical shape convex towards the inside of the radial retention space, the bearing parts having an elongated body.
