Abstract

An elastic spacer to be inserted between adjacent balls of a ball bearing and having recesses on its faces turned toward the balls into which the balls partially engage, characterized in that the spacer (1) has an outer contour (3) that can be inscribed in a cylinder and its length (L) corresponds to at least one half the diameter of the ball and has in its bore a conical partition (4) which, at least in its central region contiguous to the cone tip (5), is subdivided into elastically resilient tongues (7) by slots (6) extending approximately radially, one ball (2) making approximately punctiform contact in the center and the other ball (2) abutting on the partition (4) in a contact circle.
