Fixed Displacement Hydraulic Motor A2FE
1.Fixed displacement motor A2FM of axial piston , bent axis design,suitable for hydrostatic drives in open and closed circuits.
2.Use in mobile and industrial applications
3.The output speed depends on the flow capacity of the pump and the displacement of the motor
4The torque increases with the pressure different between the high and low pressure side and with increasing displacement
5.One piece pistons with piston rings

Fluid Recommendations
| Operatingtemperature range | DIN51519 or ISO(VG) Recommendations viscosity class to DIN51519ISO(VG) |
| 30-40℃ | VG22 22mm2/s at 40°C |
| 40-50℃ | VG35 32mm2/s at 40°C |
| 50-60℃ | VG46 46mm2/s at 40°C |
| 60-70℃ | VG68 68mm2/s at 40°C |
| 70-80℃ | VG100 100mm2/s at 40°C |
Filtration of Fluid
Recommended filtration:10um,Coarser filtration of 25-40um,is possible,but with filtration of10um.longer service life life is obtained (reduce wearing).
Speed Range
No limitation on minimum Speed nmin,if high uniformity of rotation is required, nmin should not be lower than 50 rpm.See table for maximum Speed nالحد الأقصى.
Mounting Position
Optional.The housing must always be filled with oil.
