Definition - A Brun Thrust Shaft is a specially designed shaft used to transmit rotational motion while absorbing and controlling axial (thrust) loads generated during machine operation. Its purpose is to maintain proper alignment of rotating components and safely transfer thrust forces to thrust bearings or support structures, preventing damage and ensuring smooth operation. Brun thrust shafts are commonly used in heavy industrial machinery, gearboxes, rolling mills, and power transmission systems where significant axial forces are present.
