01Key advantages of the Rexroth AZPF series:
02High efficiency: pressure-dependent gap sealing minimizes internal losses.
03Low noise and vibration: special 12-tooth geometry ensures uniform flow.
04High load capacity: robust plain bearings easily withstand high radial and axial forces.
05Ideal power-to-weight ratio: the high-pressure aluminum housing is lightweight and durable.
06Long service life: flexible tubular bearings protect the system against wear even at low-speed operation.
07High operating pressure: steadily withstands continuous pressure up to 250 bar and peak pressure up to 280 bar.
08Modularity and compatibility: available with different shafts, flanges, and multi-section combinations.
