ABSTRACT:
A radial roller bearing and a bi-directional ball bearing are mounted in the annular space separating a rotatable outer member and a stationary inner member. The bi-directional ball bearing has a pressed metal cup with a radially extending end flange. Balls and at least one thrust plate is provided in the metal cup.
The dimensions and locations of the cup, balls, and thrust plates are such that an axial force on the pressed metal cup in a predetermined axial direction causes the end flange to come into contact with either the balls or a thrust plate, depending on their axial locations within the cup, and an axial force in the other axial direction causes the end flange to break such contact.
