A2FM Bent Axis Hydraulic Motor

Eternal Hydraulic – Rexroth Type A2FO/A2FM Bent Axis Fixed Displacement Piston Pump/Motor

The A2FM is a fixed bent axial piston hydraulic motor with axial tapered piston rotary group in bent-axis design for hydrostatic drives in open circuits. Flow is proportional to drive speed and displacement. For axial piston units with bent-axis design, the pistons are arranged diagonally with respect to the drive shaft.
In an open circuit, the hydraulic fluid flows from the reservoir to the hydraulic pump from where it is fed via a directional valve to the consumer, e.g. hydraulic motor. From the consumer, the hydraulic fluid flows back to the reservoir via the directional valve.
This motor is available in sizes: 10 | 12 | 16 | 23 | 28 | 32 | 45 | 56 | 63 | 80 | 90 | 107 | 125 | 160 | 180 | 250.

APPLICATION

Piston pumps are widely used in high-pressure, high-flow, high-power systems and where the flow needs to be regulated, such as mobile and construction equipment, engineering vehicles, heavy-duty planers, metal forming and stamping, machine tools, hydraulic presses, oilfield equipment, mining and metallurgical machinery, marine,  etc.
