- Family markers describe reference applicability. Component links are released source-BOM listings and do not assert complete engineering containment.
FAMILY REFERENCE APPLICABILITY
Family profiles carrying a source marker.
Unmarked Families are not listed; an unmarked cell means “not normally fitted” in the source Family profile, not confirmed absence from a vessel.

Thrust shaft
추력축The shaft section carrying the propeller's forward push into the thrust bearing — the point where thrust becomes hull movement.
Design dependent · As required / design dependentView Component record →COMP-291 · MechanicalIntermediate shafts
intermediate shaftsThe shaft lengths between engine and stern tube, bolted together to span the distance from machinery space to propeller.
Design dependent · As required / design dependentView Component record →COMP-292 · MechanicalThrust bearing
thrust bearingThe bearing that absorbs propeller thrust and transmits it to the ship's structure, letting the shaft rotate while pushing the hull.
Design dependent · As required / design dependentView Component record →COMP-293 · MechanicalShaft line bearings
라인 bearingsSupport bearings along the shaft line that keep it aligned and carry its weight between engine and stern tube.
Design dependent · As required / design dependentView Component record →COMP-294 · MechanicalShaft couplings
couplingsThe bolted flanges or fitted couplings joining shaft sections into one continuous power path.
Design dependent · As required / design dependentView Component record →COMP-295 · MechanicalShaft brake / locking device
brakeA shaft brake or locking device that stops and holds the shaft — needed for maintenance and to prevent windmilling when not in use.
