Axial-piston hydraulic motors МГ type of constant displacement
Axial-piston hydraulic motors of constant displacement, type МГ, are designed for installation in hydraulically-driven mechanisms on sea-going vessels and in various devices of general industrial application.
Available are hydraulic motors in a variety of standard sizes. Each standard size includes right- and left-hand versions as well as versions with both directions of driving shaft rotation.
A considerable advantage of our hydraulic motors as compared with similar machines is availability of modifications with hydrostatic unloading of bearings in the driving unit which allows to increase the motor service life up to 14000 hours.
