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.
