Data Sheet of A2FO Series

REXROTH Type Code of A2FO Series

 

 

 

General instructions

–The pump A2FO is designed to be used in open circuits.

–The project planning, installation and commissioning of the axial piston unit requires the involvement of qualified personnel.

–Before using the axial piston unit, please read the corresponding instruction manual completely and thoroughly. If necessary, these can be requested from Bosch Rexroth.

–During and shortly after operation, there is a risk of burns on the axial piston unit. Take appropriate safety measures (e. g. by wearing protective clothing).

–Depending on the operating conditions of the axial piston unit (operating pressure, fluid temperature), the characteristic may shift.

–Service line ports:

  - The ports and fastening threads are designed for the specified maximum pressure. The machine or system manufacturer must ensure that the connecting elements and lines correspond to the specified application conditions (pressure, flow, hydraulic fluid, temperature) with the necessary safety factors.

  - The service line ports and function ports can only be used to accommodate hydraulic lines.

–The data and notes contained herein must be adhered to.

–The product is not approved as a component for the safety concept of a general machine according to ISO 13849.

–A pressure-relief valve is to be fitted in the hydraulic system.

–The following tightening torques apply:

  - Fittings: Observe the manufacturer's instructions regarding tightening torques of the fittings used.

  - Mounting bolts: For mounting bolts with metric ISO thread according to DIN 13 or with thread according to ASME B1.1, we recommend checking the tightening torque in individual cases in accordance with VDI 2230.

  - Female threads in the axial piston unit: The maximum permissible tightening torques MG max are maximum values for the female threads and must not be exceeded. For values, see the following table.

  - Threaded plugs: For the metallic threaded plugs supplied with the axial piston unit, the required tightening torques of threaded plugs MV apply. For values, see the following table.

Technical data

1) These values are valid at:
- an absolute pressure of pabs = 1 bar at suction port S
- for the optimum viscosity range from vopt = 36 to 16 mm2/s
- with hydraulic fluid based on mineral oils
2) Maximum speed (limiting speed) with increased inlet pressure pabs at suction port S, see the following diagram.
3) Torque without radial force, with radial force see table "Permissible radial and axial forces of the drive shafts"
