Provided is a support apparatus for a sliding frame including a stationary portion having a long axis parallel to a plane defined by the frame and including one or more magnetic insert disposed along a long axis defining a path of translation and a movable portion attached to the frame, including at least one magnetic insert and movable along the path of translation and wherein the magnetic field vector orientation of the stationary portion magnetic inserts and of the movable portion magnetic inserts are the same, generate repelling forces and maintain a single state of contactless equilibrium between the stationary portion and the movable portion at any point throughout the path of translation regardless of the orientation of said plane.
