The MCR radial piston motors are slowly running hydraulic motors which operate according to the multiple-stroke principle.
The relationship between roll diameter and cam profile is optimized inside the central power unit. This results in the best possible balance of forces between piston and cam path and simultaneously extends the service life. The step-piston power unit or high-displacement power unit yields a very compact drive unit with high power density. MCR motors can be used both in open as well as in closed circuits.
