ABSTRACT:
A vacuum deposition apparatus comprises a cabinet having a vacuum chamber defined therein. A door is movably mounted on the cabinet for movement between a closed position fully sealing an opening to the vacuum chamber and an opened position fully exposing the opening. The door is preferably mounted on the cabinet for swinging movements towards and away from the opening and for vertical sliding movements whereby the door may be moved downwardly to a remote position. The door is preferably counterweighted to facilitate its vertical sliding movements and is pivotally mounted on a bracket by self-centering bearing assemblies which are pre-adjusted to continuously insure a positive static seal as between the door and the opening to the vacuum chamber.
