    What is the function of the main thrust bearing?

  • #2


    Transmitting propeller thrust to the hull.

    In case of thrust bearing, there is a thrust collar and a pad. Due to the power produced by the engine, axial thrust is produced because the power is transmitted to the

    propeller shaft and the load is taken by the propeller blades. This loading of the propeller blades will try to push the propeller inwards and along with that the thrust

    will be transmitted in the form of axial thrust to the propeller shaft and then to the crankshaft. This thrust will be transmitted to the ship side through the collar which

    is an integrated part of the propeller shaft or the crankshaft and the pads which are fitted on the forward side during the forward running and to the aft side during

    the astern running. The thrust is transmitted to the ship’s hull as this is useful which helps in moving the ship in the desired direction.
