Abstract: A tandem ball bearing, including: an axis of rotation; outer and inner races; a cage radially disposed between the inner and outer races and including a surface, the surface facing at least partially in a first axial direction and bounding a portion of the cage extending furthest in the first axial direction; a first roller ball disposed in the cage and radially disposed between the inner and outer races; a second roller ball disposed in the cage radially outwardly of the first roller ball; and a channel bounded by the inner race and the cage and including an opening facing in the first axial direction and bounded by the inner race and the first surface of the cage. A first line, in a second axial direction, opposite the first axial direction, passes through in sequence: the cage; the channel; the inner race; and the first roller ball.

Abstract: A linear contactless displacement sensor assembly is provided. The sensor assembly can include a shaft configured to translate linearly, and a sleeve rotatably coupled about the shaft and linearly fixed such that the shaft can linearly translate through the sleeve as the sleeve rotates. The sleeve includes an outer surface having a threading that varies in pitch. A tooth is disposed in the threading and fixed on a linear track such that the tooth moves linearly as the sleeve rotates. A sensor is configured to sense a location of the tooth along the linear track. This allows the sensor assembly to measure an amount of linear movement and a corresponding amount of rotation of the sleeve.
