Project planning notes
The Axial piston fixed motor A4FM is designed to be used in open and closed circuits.
Project planning, installation and commissioning of the axial piston units requires the involvement of skilled personnel.
Before using the axial piston unit, please read the appropriate instruction manual thoroughly and in full. If necessary, this can be requested from
Bosch Rexroth.
Before finalizing your design, request a binding installation drawing.
The specified data and notices contained herein must be observed.
Preservation: Our axial piston units are supplied as standard with preservative protection for a maximum of 12 months. If longer preservative protection is required (maximum 24 months), please specify this in
plain text when placing your order. The preservation periods apply under optimal storage conditions, details of which can be found in the data sheet 90312 or the instruction manual.
For drives that are operated for a long period with constant rotational speed, the natural frequency of the hydraulic system can be stimulated by the excitation frequency of the pump (rotational speed frequency
×9). This can be prevented with suitably designed hydraulic lines.
Please note the details regarding the tightening torques of port threads and other threaded joints in the instruction manual.
Working ports:
The ports and fastening threads are designed for the specified maximum pressure. The machine or system manufacturer must ensure the connecting elements and lines correspond to the specified application conditions (pressure, flow, hydraulic fluid, temperature) with the necessary safety factors.
The service ports and function ports are only designed to accommodate hydraulic lines.
