Toshiba SG020 MFB45 MFC45 hydraulic motor specifications

The Toshiba SG020 MFB45 MFC45 hydraulic motor is an axial piston hydraulic gear motor designed to drive the slewing mechanism of construction machinery, mainly crawler excavators. This unit combines a high-speed hydraulic motor and a planetary gearbox, which provides high torque and low rotational speed, necessary for smooth and precise slewing of the machine platform. It is an OEM component, so its characteristics are closely related to the hydraulic systems of the excavators in which it is installed.
