The present invention relates to a stern tube bearing unit for supporting a propeller shaft, comprising: a first bearing housing installed on a casting on a propeller side of a ship body; a second bearing housing installed on a casting on an engine side of the ship body by being apart from the first bearing housing; a connection tube connecting the first bearing housing to the second bearing housing; and a second sealing means installed on a bow side of a first resin injection space formed between the first bearing housing and the casting on the propeller side. The second sealing means includes: an expansion seal installed to cover the outer circumferential surface on one side of the first bearing housing to be expandable by gas injection into the inside; and a pressure support member installed on the first bearing housing on the bow side of the expansion seal to support the pressure applied to the expansion seal when the resin is being charged. The present invention aims to provide a stern tube bearing unit and an installation method thereof, which are able to improve the steering and propelling performance of the rudder.
