MCR
xeriwell or others
Hydraulic motors of the type MCR are radial piston motors with rear case mounting and flange shaft. The MCR motors are intended for wheel drives in open or closed circuits. These motors are used in a wide range of applications such as municipal vehicles, fork lift trucks,
agricultural and forestry machines. The integrated flange with wheel studs allows easy installation of standard wheel rims.
Features:
1) Compact robust construction
2) High volumetric and mechanical efficiencies
3) Rear case mount
4) Wheel flange with wheel studs
5) High reliability
6) Low maintenance
7) Smooth running at very low speeds
8) Low noise
9) Bi-directional
10) Sealed tapered roller bearings
11) High radial forces permitted on drive shaft
12) Freewheeling possible
13) Available with:
– Holding brake (multi-disc)
– Bi-directional two speed
– Integrated flushing valve
– Speed sensor
