Product Description

Hydraulic Sauer-Sundstrand axial piston motor MF20, MF21, MF22, MF23, MF24, MF25, MF26, MF27

Product Description

The Sauer MF axial piston variable displacement motors, Series 20, are of swash plate construction with variable flow capability suitable for hydrostatic transmissions with closed circuit. TThe latter is infinitely adjustable between zero and maximum displacement. Flow direction is reserved by titling the swash plate to the opposite side of the neutral or zero displacement position. These units and parts are fit, form and function replacements for Sauer-Sundstrand series 20 components.
  Features 
The full-length shaft with a high efficient tapered roller bearing arrangement offers a high loading capacity for external radial forces. Additional motors can be built on. The hydro-mechanical servo displacement control maintains the selected swash plate position and hence motor displacement. Upon release of the control handle, the swash plate automatically returns to the null position and the flow become zero. High case pressures can be archived without leakage even at the lowest temperature by using suitable shaft seals. The servo valve arrangement offers the facility to incorporate function regulators and remote control system. Axial piston units are designed for easy servicing, complete dismantling and reassembly can be carried out standard hand tools, and all components or sub-assemblies are replaceable.
