A special motion of the dual unit sphere is studied and then with help of the Study map interpreted in the space of lines of three-dimensional Euclidean space. The motion is defined so that two points of the moving dual unit sphere are restricted to move on two circles. This gives a generalisation of a spherical slider-crank motion. The tree line congruences which are the Study maps of the paths of endpoints of the moving frame are studied.
