A2FM oblique axis quantitative motor
The A2FM series motors are designed with a skewed shaft construction, which ensures stability and reliability in a variety of applications. The one-piece plunger design with plunger ring increases the durability and reliability of the unit for long hours and high loads.
It is suitable for hydraulic transmission in open or closed circuit, walking machinery, engineering vehicles, agricultural machinery, coal machinery, special machinery and other industrial fields.

Product features
◉ Oil filtration: The recommended filtration accuracy is 10 μ m. Coarse filters between 25-40um can be used, but using a 10 μ m filter can extend the service life (reduce wear).
◉ Speed range: The minimum speed n is not limited. If uniform rotation is required, n should not be less than 50rpm.
◉ Compact structure: The A2FE series inclined shaft dosing motors are characterized by compact structure and small size because the mounting flange is designed in the middle of the casing and the mounting part can be hidden deep inside the machine.
◉ High speed and high pressure: A2FE hydraulic motors offer high power density and total efficiency with high initial efficiency. Its robust bearing system and compact structural design give the motor a long service life and high stability.

|
1) Values apply: |
2) Intermittent maximum speed: overspeed during unloading and overhaul, t<5 seconds and Δp<150 bar |
|
In the optimum viscosity range:Vopn=16~36mm²/s |
3) Limit the inlet flow with a balancing valve. |
|
Application of mineral oil-based hydraulic fluids |
4) Without radial force torque. |
