2�5 General safety instructions
• Observe the country-specic accident prevention and environmental protection
regulations.
• Observe the safety regulations of the country in which the product is
used/operated.
• Use Rexroth products only when they are in good working order.
• Observe all notices on the product.
• Do not assemble, operate, remove or maintain Rexroth products if under the
inuence of alcohol, drugs or medication that may affect your reaction time.
• Only use genuine Rexroth accessories and spare parts to ensure there is no
hazard to persons from unsuitable spare parts.
• Observe the technical data and ambient conditions specied in the product
documentation.
• If unsuitable products are installed or used in safety-relevant applications,
unexpected operating conditions may occur in the application, which could result
in personal injury or property damage. For this reason, only use the product in
safety-relevant applications if this use is expressly indicated and approved in the
product documentation, e. g.in explosion protection areas or in safety-related
parts of acontrol system (functional safety).
• Only commission the product if it has been determined that the end product
(e.g.machinery/system) in which the Rexroth products are installed complies
with the country-specic provisions, safety regulations and standards for the
application.
• Use tools appropriate for the work being performed and wear appropriate
protective clothing to prevent punctures and cuts (e.g.when removing
protective covers, disassembly).
• There is arisk of entanglement when operating the axial piston unit with
abare shaft end. Check whether or not your machine requires additional safety
measures for your application. If necessary, make sure these are appropriately
implemented.
• Depending on the type of control used, electromagnetic effects can be produced
when using solenoids. Applying adirect voltage signal (DC) to solenoids does
not create electromagnetic interference (EMI) nor is the solenoid affected
by EMI. Potential electromagnetic interference (EMI) exists if the solenoid is
energized with amodulated direct current (e.g.PWMsignal). Appropriate testing
and measures should be taken by the machine manufacturer to ensure other
components or operators (e.g.with pacemaker) are not affected by this potential.

Safety instructions | A10VOH145 series 60 11/56
2�6 Product-specic safety instructions
The following safety instructions apply to chapters 6 to 14.
WARNING
Danger due to excessive pressure!
Risk of death or injury, or property damage!
Improperly changing the factory pressure settings can result in apressure
increase beyond the permissible maximum pressure.
Operating the unit above the maximum permissible pressure can cause
components to burst and hydraulic uid to escape under high pressure.
▶ Changes to the factory settings may only be made by BoschRexroth
specialists.
▶ In addition, apressure relief valve is required in the hydraulic system
as back-up. If the axial piston unit is equipped with apressure cut-off
and/or pressure controller, this is not an adequate safeguard against
pressure overload.
Danger due to suspended loads!
Risk of death or injury, or property damage!
Improper transportation may cause the axial piston unit to fall down and lead to
injury, e.g.crushing or fracture, or damage to the product.
▶ Make sure that the load bearing capacity of the lifting device is sufcient to
safely bear the weight of the axial piston unit.
▶ Never step or grip under suspended loads.
▶ Ensure astabletransport position.
▶ Use your personal protective equipment (e.g.safety goggles, safety gloves,
suitableworking clothes, safety shoes).
▶ Use suitablelifting devices for transport.
▶ Observe the prescribed position of the lifting strap.
▶ Observe the national laws and regulations on occupational health and safety,
and transportation.
System/machine under pressure!
Risk of death or serious injury when working on unsecured machines/systems!
Property damage!
▶ Switch off the relevant machine/system part and secure it against reactivation
according to the parameters by the machine/system manufacturer.
▶ Ensure that all relevant components of the hydraulic system are depressurized.
For this purpose, observe the parameters indicated by the machine/system
manufacturer.
▶ Please note that the hydraulic system might still be pressurized even after
separation from the actual pressure supply.
▶ Do not disconnect any line connections, ports or components as long as the
hydraulic system is under pressure.

BoschRexrothAG, RE 92704-01-B/2022-12-07
12/56 A10VOH145 series 60 | Safety instructions
WARNING
Escaping hydraulic uid mist!
Risk of explosion and re hazard, health hazard, risk of environmental pollution!
▶ Depressurize the relevant machine/system component and repair the leak.
▶ Only perform welding work when the machine/system is depressurized.
▶ Keep open ames and ignition sources away from the axial piston unit.
▶ If axial piston units are located in the vicinity of ignition sources or
powerful thermal radiators, ashield must be erected to ensure any
escaping hydraulicuid cannot be ignited, and to protect hose lines from
premature aging.
Escaping hydraulic uid due to leakage of machine/system components!
Risk of burning and risk of injury due to escaping hydraulic uid jet!
In case of leakage at the axial piston unit, high-pressure
uid jets may escape.
▶ Depressurize the relevant machine/system component and repair the leak.
▶ Never attempt to block or seal the leak or hydraulic uid jet with acloth.
Hydraulic uid will explode when making contact with water!
Explosion and re hazard!
▶ Do not bring hot hydraulic uids in contact with water.
Electrical voltage!
Danger to life or risk of injury due to electric shock or property damage!
▶ Always disconnect the voltage supply to the relevant machine/system
part before installing the product and/or connecting or disconnecting the
connector. Protect the machine/system against being re-energized.
Restriction of control function!
Risk of injury or property damage!
Under certain circumstances, moving parts in control equipment
(e.g., valve spools) can get stuck in an undened position due to contamination
(e.g., impure hydraulic uid, abrasion or residual dirt from components).
As aresult, the hydraulic uid ow and the build-up of torque in the
axial piston unit can no longer respond correctly to the operator’s specications.
Even the use of various lter elements (external or internal ow ltration) will not
rule out afault but merely reduce the risk.
▶ Check whether your application requires remedial measures on your machine
in order to bring the driven consumer to asafe position (e.g.safe stop).
▶ If necessary, make sure these are appropriately implemented.

RE 92704-01-B/2022-12-07, BoschRexrothAG
Safety instructions | A10VOH145 series 60 13/56
CAUTION
High noise development during operation!

3 General instructions on property
damage and product damage
The following notices apply to chapters 6 to 14.
NOTICE
Danger from improper handling!
Product can be damaged!
▶ Do not subject the product to improper mechanical loads.
▶ Never use the product as handle or step.
▶ Do not put/place any objects on the product.
▶ Do not strike the drive shaft of the axial piston unit.
▶ Do not set/place the axial piston unit on the drive shaft or assembled parts.
▶ Do not strike assembled parts (e.g. sensors. solenoids or valves).
▶ Do not hit sealing surfaces (e.g.on the working ports).
▶ Leave the protective covers on the axial piston unit until you connect the lines.
▶ Disconnect all electrical connectors before arc welding and painting
operations.
▶ Make sure the electronic components (e.g.sensors) do not build up
electrostatic charges (e.g.during painting operations).
Risk of property damage due to inadequate lubrication!
Product can be damaged or destroyed!
▶ Never operate the axial piston unit with insufcient hydraulic uid.
Specically, make sure that the rotary group has sufcient lubrication.
▶ When commissioning amachine/system, make sure that the housing area and
the working lines of the axial piston unit are lled with hydraulic uid and
remain lled during operation.
▶ Check the hydraulic uid level in the housing area regularly and replenish,
if necessary. For above-reservoir installation, the housing area may drain out
through the drain line after prolonged standstill periods (air enters through
the shaft seal) or through the working line (gap leakage). This means the
bearings are insufciently lubricated when the system is turned on.
▶ Make sure the suction line is always lled with hydraulic uid during
commissioning and operation.
▶ Ensure in case of above-reservoir installation that before initial start-up of the
axial piston pump (commissioning or recommissioning), the suction line is
completely lled with hydraulic uid. Make certain that the axial piston pump
does suck in hydraulic uid and build up pressure directly after start-up.
In case of longer standstill, suitable measures have to be taken to prevent
draining of the suction line.

5�1 Performance description
The axial piston variable pump generates, controls and regulates ahydraulic uid
ow. The A10VOH145 is designed for mobile applications such as construction
machinery.
Refer to data sheet 92704 and the order conrmation for the technical data,
operating conditions and application limits of the axial piston unit.
5�2 Product description
The A10VOH145 is avariable pump with axial piston rotary group of
swashplate design for hydrostatic drives in an open circuit hydraulic system.
Flow is proportional to drive speed and displacement. The ow can be steplessly
changed by controlling the cradle (13). For axial piston units with swashplate
design, the pistons (11) are arranged axially to the drive shaft (1).
In an open circuit, the hydraulic uid ows from the reservoir to the
hydraulic pump from where it is fed to the consumer, e.g. hydraulic motor.
From the consumer, the hydraulic uid ows directly back to the reservoir.

5�2�2 Functional description
Torque and rotational speed are applied to the drive shaft(1) by adrive motor.
The cylinder (10) is picked up and turned by the splines of the drive shaft.
With every revolution, the pistons(11) complete astroke in the cylinder bores,
the size of which depends on the pitch of the cradle(13). The slipper pads (12)
are held on with the pistons and guided along the glide surface of the cradle by
the retaining plate (3). The inclined position of the cradle during arotation causes
each piston to move over the bottom and top dead centers and back to its initial
position. During this sequence, hydraulic uid is fed in and drained out through
the two control slots in the control plate (7) according to displacement.
On the suction side (9) hydraulic uid ows into the piston chamber as the
piston recedes. At the same time, on the high-pressure side (6) the hydraulic uid
is pushed out of the cylinder chamber into the hydraulic system by the pistons.
The swivel angle of the cradle(13) is continuously adjustable. Adjusting the swivel
angle changes the piston stroke and, with it, the displacement. The swivel angle is
controlled hydraulically by means of the stroking piston. The cradle is mounted for
easy motion in swivel bearings. When pressurized, the cradle is held in balance by
the swiveling forces of the rotary group, which are generated by the eccentrically
mounted cradle and by the control pressure. When depressurized, the spring (2)
presses the swashplate to maximum swivel angle. Increasing the swivel angle
increases the displacement; reducing the angle reduces displacement accordingly.
Various control devices are available depending on requirements.
Information about this can be found in data sheet 92704.
