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.

Abstract: The ball bearing comprises a pressed metal cup in which are loosely-mounted axially-spaced, pressed metal thrust washers which contact a plurality of balls. The thicknesses of the thrust washers and the diameter of the balls are chosen so that an axial clearance between the metal cup and a thrust washer is provided in response to an axial force.

Abstract: The radial and bi-directional thrust bearing has a stationary, inner-annular race and a pair of rotatable outer races in tandem. The outer races each have a radially, inwardly-directed annular shoulder which is in contact with a radially, inwardly-directed annular shoulder of the other outer race. The inside diameters of the outer races are equal and larger than the outside diameter of a stationary, inner race, thus providing an annular space.Two tandem sets of rollers are mounted in the annular space. A radially, outwardly-extending shoulder is provided on the inner race and extends partially across the annular space. A thrust ring is also mounted about the inner race. A sealing member extends across the annular space between the inner race shoulder and one outer race, and another sealing member extends across the space between the thrust ring and the other outer race.

Abstract: The ball bearing comprises a pressed metal cup in which are loosely-mounted axially-spaced, pressed metal thrust washers which contact a plurality of balls. The thicknesses of the thrust washers and the diameter of the balls are chosen so that an axial clearance between the metal cup and a thrust washer is provided when the other thrust race engages the cup and the balls are in contact with both thrust washers.
