A device for transforming a rotational movement into a linear movement. The device comprises a retainer and a shaft extending through the retainer which are mounted for movement relative to one another. A plurality of annular bearing members, in the illustrated embodiment, comprising ball bearings, circumscribes the shaft and engages the same at axially spaced locations. The bearings are mounted for tilting movement relative to the shaft. The outer ring of each of the bearing assemblies is supportd in a housing and each housing has an external surface section defined by a circular arc having a center on the rotational axis of the housing which slidingly engages internal walls of the retainer of complementary form. |
