A turbomachine includes a vane, a rotation support coupled to an end of the vane, and a spindle coupled to the rotation support. The spindle, the vane, and the rotation support are rotationally aligned. An annular sleeve defines the spindle. The annular sleeve contacts the rotation support at a radially inward extent and contacts a turbine casing at a radially outward extent. A first rolling element engages the annular sleeve substantially near the radially outward extent. The first rolling element is coupled to the turbine casing. A second rolling element engages the annular sleeve substantially near the radially inward extent. The second rolling element is coupled to an outer endwall ring. A center of mass of the annular sleeve is positioned between the first and second rolling elements.
