<p>An apparatus for moving a stabilizing fin (P) of a vessel comprises a casing (10) with inner cavities (13, 15), provided with bearing units for rotatably supporting the casing about a vertical axis (A) with respect to a fixed structure (16) of the vessel. Other bearing units (64, 66) rotatably support an oscillating shaft (48) of the fin (P) about a horizontal axis (B). A lubrication circuit (50) comprises tubes (56) extending in the cavity (13, 15) of the casing (10). The tubes communicate with a series of inlets (52) for supplying lubricant through passage bores (53, 58, 68a, 68b, 72a, 72b, 72c) formed through the casing, so as to lubricate the surfaces of the bearing units (18, 20, 64, 66) subjected to rolling or sliding.</p> |
