01Key advantages of the Rexroth A2F series:
02High efficiency
03Spherical valve plate: uses a reliable spherical control surface.
04Self-centering: the cylinder block automatically aligns with the working surface.
05Low friction: low peripheral speed reduces internal losses and wear.
06High volumetric efficiency: maximizes hydraulic power with minimal energy loss.
07Mechanical strength and robust construction
08High load capacity: the drive shaft is designed for high radial and axial forces.
09Heavy-duty bearings: bearings designed for severe working conditions provide long service life.
10Resistance to pressure shocks: the bimetallic cylinder withstands sudden pressure spikes.
11Operational flexibility
12Dual function: operates as both a hydraulic pump and a hydraulic motor.
13Fluid compatibility: works with standard mineral oils, environmentally friendly fluids, and fire-resistant fluids.
14High operating pressure: withstands up to 400 bar nominal pressure and up to 450 bar peak pressure.
15Compactness: bent-axis geometry delivers high power in a compact housing.
16Easy system integration
17Standard flanges: equipped with SAE and ISO mounting options, simplifying installation in heavy machinery and equipment.
18Low noise level: optimized internal channels significantly reduce vibration and noise.
19Wide size range: available in different displacements, from 5 cm³ to 1000 cm³ per revolution.
