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. Other permissible limit values, such as speed variation, reduced angular acceleration as a function of the frequency and the permissible angular acceleration at start (lower than the maximum angular acceleration) can be found in data sheet 90261.

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:

Note
The service life of the shaft seal is influenced by the speed of the axial piston unit and the case pressure. The service life decreases with an increase of the mean differential pressure between the case and the ambient pressure and with a higher frequency of pressure spikes. The case pressure must be equal to or higher than the ambient pressure.Direction of flow

General information
The specified values are maximum data and not approved for continuous operation. The axial force in the direction of action -Fax is to be avoided as this reduces the bearing life cycle. The output by means of belts requires special conditions. Please consult us.
Notes for sizes 250 ... 1000:
In case of radial forces limited performance data is valid. Please contact us. In case of axial forces during operation of the unit please contact us.Effect of radial force Fq on the service life of bearings
By selecting a suitable direction of radial force Fq the load on the bearings caused by the internal rotary group forces can be reduced, thus optimizing the service life of the bearings. Recommended position of mating gear is dependent on direction of rotation. Examples:
Toothed gear drive, size 5 … 180

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. Particularly in the installation position "drive shaft upwards" filling and air bleeding must be carried out completely as there is, for example, a danger of dry running. The case drain fluid in the housing must be directed to the reservoir via the highest available drain port (T1,T2). 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 suction and drain lines must lead into the reservoir below the minimum fluid level. The permissible suction height hS results from the overall loss of pressure; it must not, however, be higher than hS max = 800 mm. The minimum suction pressure at port S must also not fall below 0,8 bar absolute during operation and during cold start. When designing the reservoir, ensure adequate space between the suction line and the drain line.This provides a slow-down and desgasification of the fluid and prevents that heated return flow is being drawn directly back into the suction line.Installation position
See the following examples 1 to 8.
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.

Above-reservoir installation
Above-reservoir installation means that the axial piston unit is installed above the minimum fluid level of the reservoir.
Recommendation for installation position 8 (drive shaft upward): A check valve in the drain line (cracking pressure 0,5 bar) can prevent draining of the pump housing.

The axial piston unit is designed to be used in open 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).
