Abstract

A plastic snap cage for radial ball bearings includes thin-walled cup-like pocket elements spaced about the circumference and connected with each other in one piece through ribs, thereby forming pockets that are open in the axial direction to receive the balls. The radially inwardly and/or the radially outwardly extending boundary edge of the pockets is rounded in accordance with a selected rounding radius R.
