A bearing retention clip design for securing ball bearings to a frame mount is disclosed. Ball bearing mounted shafts with unrestrained outer races tend to rotationally migrate and may eventually damage or destroy the frame mount. As shown in Figure 1, bearing retention clip 1 (rear perspective 5) prevents rotational migration by applying an interference clamping force on a bearing outer race. The bearing and clip when located in a notched or "keyhole" shaped opening 2 effectively locks the bearing outer race (rear perspective 6) to the frame plate 3 (rear perspective 7). The clip is fastened to the frame plate with, for example, a tread forming screw 4, which locates and secures the bearing and shaft assembly in an axial direction. Plan views of the clip 1 are shown in Figure 2. The design provides low cost and compactness allowing for easy integration into a wide variety of design spaces.
