Note

The values in the table are theoretical values, without consideration of efficiencies and tolerances. The values are rounded. Exceeding the maximum or falling below the minimum permissible values can lead to a loss of function, a reduction in operational service life or total destruction of the axial piston unit. We recommend testing the loads by means of experiment or calculation / simulation and comparison with the permissible values.

Explanatory note regarding the selection of hydraulic fluid

The hydraulic fluid should be selected such that the operating viscosity in the operating temperature range is within the optimum range (vopt see selection diagram).

Selection diagram

Filtration of the hydraulic fluid

Finer filtration improves the cleanliness level of the hydraulic fluid, which increases the service life of the axial piston unit.

A cleanliness level of at least 20/18/15 is to be maintained according to ISO 4406.

At a hydraulic fluid viscosity of less than 10 mm²/s (e.g. due to high temperatures in short-term operation) at the drain port, a cleanliness level of at least 19/17/14 according to ISO 4406 is required.

For example, the viscosity is 10 mm²/s at:

HLP 32 a temperature of 73°C HLP 46 a temperature of 85°C

Flushing and boost pressure valve

The flushing and boost pressure valve is used in closed circuits for the removal of heat and to ensure a minimum boost pressure level.

Hydraulic fluid is directed from the respective low pressure side into the motor housing. This is then fed into the reservoir, together with the leakage. The removed hydraulic fluid must be replaced by cooled hydraulic fluid from the boost pump.

The valve is integrated into the port plate.

Flushing flow qv

Orifices can be used to set the flushing flows as required.

The specifications below are based on:

ΔpND = pND – pG = 20 bar and ν = 10 mm²/s

(pND = low pressure, pG = case pressure)

Standard flushing flow is 5.5 l/min with orifice ⌀1.6 mm. Other orifice diameters are available, please state in clear text when ordering.

Anti-cavitation valve

When stopping a system with a relatively large mass (i.e. fan drive) the anti-cavitation valve provides fluid to the motor inlet during the coasting time.

The valve is integrated into the port plate.

Please note:

Then direction of rotation must be fixed to clockwise or counter clockwise during project planning.

The outside dimensions of the motor with anti-cavitation valve are identical to the standard version.

Circuit diagram

Speed sensor

The version A10F...D ("Prepared for speed sensor", i.e. without sensor) is equipped with an extra port D for installation of a suitable sensor and with a toothed ring on the rotary group. The toothing can be scanned by a sensor and a speed-proportional signal can thus be generated.

On deliveries the sensor port D is plugged with a pressure-resistant cover.

Installation instructions

General

During commissioning and operation, the axial piston unit must be filled with hydraulic fluid and air bled. This must also be observed following a relatively long standstill as the axial piston unit may drain back to the reservoir via the hydraulic lines. The case drain fluid in the housing must be directed to the reservoir via the highest available drain port (L, L1). If a shared drain line is used for several units, make sure that the respective case pressure is not exceeded. The shared drain line must be dimensioned to ensure that the maximum permissible case pressure of all connected units is not exceeded in any operating conditions, specifically on cold start. If this is not possible, separate reservoir lines must be laid as required. To achieve favorable noise values, all connecting lines should be decoupled by using elastic elements and above-reservoir installation is to be avoided. In all operating conditions, the drain line must flow into the reservoir below the minimum fluid level.

Installation position

See the following examples 1 to 4.

Further installation positions are possible upon request. Recommended installation position: 1 and 2.

Below-tank installation (standard)

Below-tank installation is at hand if the axial piston unit is installed below the minimum liquid level outside the tank.

Installation position	Air bleeding	Filling
1	‒	L1
2	‒	L

Above-reservoir installation

Above-reservoir installation means that the axial piston unit is installed above the minimum fluid level of the reservoir.

Note

Connection F is part of the external piping and must be provided on the customer side to simplify the filling and bleeding.

General project planning notes

The axial piston unit is designed to be used in open and closed circuits. The project planning, installation and commissioning of the axial piston unit require the involvement of qualified skilled personnel. Before using the axial piston unit, please read the corresponding instruction manual completely and thoroughly. If necessary, request it from Bosch Rexroth. Before finalizing your design, request a binding installation drawing. The specified datas and notes 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 times are valid under optimal storage conditions. Details of these conditions can be found in the data sheet 90312 or the instruction manual. A pressure relief valve is to be provided in the hydraulic system. Observe the instructions in the instruction manual regarding tightening torques of connection threads and other threaded joints used. The notes in the instruction manual on tightening torques of the port threads and other screw joints must be observed. The ports and fastening threads are designed for the permissible maximum pressure pmax (see instruction manual). The machine or system manufacturer must ensure that the connecting elements and lines correspond to the specified operating conditions (pressure, flow, hydraulic fluid, temperature) with the necessary safety factors. The working ports and function ports are designated only to accommodate hydraulic lines.

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).
