Abstract: A cage for a ball bearing is optimized for high-speed applications. To reduce weight, the cage is formed by a number of conical blades which collectively form an “X” shape. To add rigidity, a number of gussets are placed between the blades at various circumferential locations. The light weight reduces the centrifugal forces for a given diameter and rotational speed. The rigidity permits the cage to withstand the centrifugal forces without excessive deflection or stress.

Abstract: A two-piece plastic ball bearing cage is designed to handle high-speed applications. Posts on one bearing half fit into holes in the other bearing half After the two halves are brought together, ultrasonic vibration is applied to the ends of the posts. The ultrasonic vibration deforms the post end to fit into a widened portion of the holes and welds material, thereby firmly securing the two cage halves to one another.
