An electrohydraulic linear actuator comprises a housing consisting of a tubular profile, which forms a housing shell and in which there is a plurality of cavities, and which is closed at the ends by two housing covers fitted to the ends of the housing shell. A first cavity of the tubular profile forms a cylinder which forms the hydraulic cylinder of a double-acting synchronous cylinder and a second cavity which extends parallel to the first cavity accommodates a hydraulic unit in addition to the hydraulic cylinder, and a hydraulic oil reservoir is formed in said second cavity. Two working chambers of the hydraulic cylinder are separated from each other by a piston unit. The housing has at least one through-hole for a coupling element which forms a mechanical interface with the piston unit. The electric motor of the hydraulic unit is configured as a brushless outrunner motor.
