Hydraulic Sauer-Sundstrand axial piston motor MF20, MF21, MF22, MF23, MF24, MF25, MF26, MF27
Description |
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.Size | Dimension | Sauer-Sundstrand MF motor | |||||||
