4/84 Hägglunds CA | Radial piston hydraulic motor
Bosch Rexroth AB, RE 15305/06.2019
Bosch Rexroth‘s hydraulic industrial motor Hägglunds CA is
of the radial piston type with a rotating cylinder block/
hollow shaft and a stationary housing. The cylinder block is
mounted in fixed roller bearings in the housing. An even
number of pistons are radially located in bores inside the
cylinder block, and the distributor directs the incoming and
outgoing oil to and from the working pistons. Each piston is
working against a cam roller.

When the hydraulic pressure is acting on the pistons, the
cam rollers are pushed against the slope on the cam ring
that is rigidly connected to the housing, thereby producing
a torque. The cam rollers transfer the reaction force to the
pistons which are guided in the cylinder block. Rotation
therefore occurs, and the torque available is proportional
to the pressure in the system.
Oil main lines are connected to ports A and C in the con-
nection housing and drain lines to one of the D -ports in the
motor housing. (See 3.2 Port connections)
The motor is connected to the shaft of the driven machine
through the cylinder block. The torque is transmitted by
splines or shrink disc coupling.

4.4 Recommended charge pressure
The hydraulic system must be such that the motor will
recieve sufficient charge pressure at the charge pressure
port (low pressure port). This applies to all types of
installations.
4.4.1 The motor working in driving mode only
The pressure at the charge pressure port (low pressure port),
should, during operation of the motor, be at least one bar
above the case pressure independent of numbers of ports
that are connected. Two cases to be considered:
Case 1: No shock loads.
Required charge pressure = case pressure + 1 bar (14.5 psi)
during operation, but shall not be below 2 bar (29.0 psi)
Case 2: With shock loads.
Required charge pressure at the outlet port corre
sponds to
30% of value given in diagram. See Fig. 5 and Fig. 6
DD00100961
4.4.2 The motor working in braking mode
For motors working in braking mode (pump mode), the
required charge pressure at the inlet port is according
to diagram. See Fig. 5 and Fig. 6.
4.4.3 The motor working in 2-speed mode
The motor is used with a 2-speed valve, VTCA 600.
Required charge pressure at inlet port for valve is according
to diagram. See Fig. 5 and Fig. 6
Fig. 5: Recommended charge pressure for motor workning in braking mode (pump mode), 2-port connection.
Valid for oil viscosity 40 cSt.
Note!
The diagrams are valid for 1 bar (14,5 psi) case pressure.
With increasing case pressure the charge pressure must
be increased accordingly.

Details regarding the selection of hydraulic fluid
The hydraulic fluid should be selected such that the
operating viscosity in the temperature range, as meas-
ured in the motor housing, is within optimum operation
range, see Fig. 7. General recommendation is to have a
system temperature of 50°C, see dotted line in Fig. 7. An
ISO VG 68 fluid will render just above 40 cSt at this point.
• Optimum viscosity range is 40 to 150 cSt.
• Running above 150 cSt or below 40 cSt results in
reduced efficiency.
• Running above 400 cSt results in substantial efficiency
loss.
• Starting at above 10 000 cSt imparts unnecessary
strain on parts.
• Running below 30 cSt may impact service life.
• Running below 20 cSt (10 cSt for option C-coated mo
-
tors) may render instant seizure.
The operating temperature is also limited by the seal type, see
Table 3: General data (metric) or Table 4: General data (US).
4.5 Hydraulic fluids
The hydraulic motor Hägglunds CA is primarily designed for
operation with hydraulic fluids according to ISO 11158 HM.
Before the start of project planning, see data sheet
RE 15414, Hydraulic fluid quick reference, for detailed
information on hydraulic fluids and specific additional
demands.
Table 7: Applicable uids
Within these standards, not all fluid classes are allowed,
some are recommended, and there are also additional
demands (see data sheet RE 15414).
Filtration of the hydraulic fluid
A contamination level better than 18/16/13 according to ISO
4406 is required.
The less contamined the fluid, the longer the service life of
the hydraulic motor.

Exemple:
Hägglunds CA 100 100 working at 250 bar and n = 50 rpm.
The CA motors have very high overall efficiency, and they
are frequently used in applications with high power.
To avoid high temperature in the case, the losses generated
in the motors must be cooled away. High temperature gives
lower viscosity and this gives reduction in basic rating life
and max allowed power for the motor.
For flushing flow inlets, see Fig. 41 and Fig. 42.
For continuous duty the motors must be flushed when the
shaft power exceed the following max power:

4.13 Freewheeling
4.13.1 The function of freewheeling
Hägglunds CA motors can be operated in freewheeling
mode.
Principally this is performed by disengaging the pistons,
allowing the rotating group to rotate as a flywheel on its
main bearings. The piston units are not engaged and thus
there is no oil flow to cause a flow loss, Hägglunds motors
of standard design are suitable for this performance due to
the following facts:
1. Pistons are not actuated by any return springs.
2. The motor case can withstand sucient case pressure
to force the pistons toward the bottom of each cylinder
bore and keep them in this position.
The basic function of the freewheeling is to have the motor
housing (via drain ports D1, D2 or D3) lightly pressurized
(see Fig. 47) while main ports A and C are without restric-
tion drained directly to the fluid reservoir. See Fig. 46. The
case pressure introduced in the normal drain connection
will then act on the outer surface of each piston assembly
pressing them towards the motor centre.
The rotating part of the motor (cylinder block with piston
and cam roller) can now rotate on its main bearings wit-
hout any pumping of oil, as the piston with cam rollers have
lost any contact with the cam ring. See Fig. 45.
During freewheeling periods, the following functions must
be performed:
1. Main connections A & C of the motor drained to reservoir.
2. Fail-safe type brake released, if used.
3. An adequate pressure introduced into the drain ports of
the motor. See Fig. 47 (required case pressure).

Note!
It is not allowed for the pistons to extend back to the cam

still.
Note!
If a motor is subject to external shock loads under
freewheeling operation, this must be subject to atten-
tion. Please contact Bosch Rexroth representative for
further information.
Radial piston hydraulic motor | Hägglunds CA 35/84
RE 15305/06.2019, Bosch Rexroth AB
To use Hägglunds CA motor in freewheeling mode must
following be maintained:
• The motor case must be pressurized all the time
when the motor is in freewheeling mode, see Fig. 47.
• The motor case must be flushed all the time when
the motor is in frewheeling mode, see Fig. 47.
An accumulator can be added into the circuit to shorten the
time to retract all the pistons completely, see Fig. 46.
An accumulator can also be added into the circuit to reduce
the pressure spikes in the motor case when the pistons are
extracted, see Fig. 46.

4.13.3 Oil volume for freewheeling
Freewheeling conditions are obtained by pressurizing the
case via the drain connections and drain the main ports to
tank. To retract all pistons completely, a certain oil volume
is required depending upon motor type. This oil volume can
be calculated from the following:
V
F

4.13.4 Freewheeling restrictions
Freewheeling in vertical position is restricted for multi cam-
ring motors
Note!
Freewheeling in vertical position > 70 rpm may increase
the risk of wear in multi cam ring motors
(CA 100/140/210).
For support regarding increased robustness in vertical
freewheeling, please contact your Bosch Rexroth repre-
sentative.

4.13.5 Power loss freewheeling
Even if the freewheeling operation takes place with lowest
possible friction in the main bearings and with no flow losses
in the main ports of the motor, a powerloss must take place
in the motor case due to viscous friction between moving
and fixed parts. This powerloss is expressed in Fig. 47.
Case flushing is required to prevent overheating,
see diagram Fig. 47
Required case pressure 1.5 -2 bar (21.8-29 psi).

*If the motor has been subject to freewheeling under e.g.
winch quick release conditions the motor should be
inspected before further use.
**Viton seals are recommended for speeds above 280 rpm.
Note!
Freewheeling will require exchange of oil in the housing
to prevent overheating.
In order to accomplish proper freewheeling, a case
pressure according to Fig. 47 has to be maintained.
On the other hand, a higher casing pressure than 2 bar
(29 psi) should be avoided in order to achieve good
service life of the main radial shaft seal.

Radial piston hydraulic motor | Hägglunds CA 43/84
RE 15305/06.2019, Bosch Rexroth AB
Speed variation data was acquired according to ISO 4392-3
where torque on the shaft and flow into the motor is held
constant.
In order to obtain smooth operation at low speed it is
important to understand that the mechanisms behind
speed variation are governed by leakage and friction
variation in the motor together with characteristics of the
load and the hydraulic system.
When the theoretical flow needed to rotate the motor is in
the same order of magnitude or less than the leakage flow
there is a risk for speed variation. Friction losses in the
motor will increase at low speed due to reduced oil film
thickness. Any variation in these friction losses may result
in speed variation.
• Speed variation resulting from both friction and
leakage will be lower with high case oil viscosity.
Recomendation is to have a case oil viscosity be-
tween 100-150 cSt.
• The load characteristics on the shaft will also affect
speed variation, for example moment of inertia,
friction effects and natural frequency.
• Smooth operation at low speed is enhanced by a
constant flow source, like a flow control valve or a
small pump that is not operating in its lower
displacement range.
• Compressibility of hydraulic oil volume between flow
source and motor and deformation of hoses may also
result in speed variation, especially if the natural
frequency of the hydraulic system and the load is
close to each other.
• Therefore, smooth operation is enhanced by a stiff
hydraulic system connecting the flow source and the
motor, i.e. using short pipings with small dimension.
4.16 Painting system
Corrosion protection
The painting system of Hägglunds motors and accessories
are avalible in two different corrosivity categories regarding
corrosion protection in accordance with SS-EN ISO 12944:
• C3 - Corrosivity category Medium - which is recom-
mended for normal urban and industrial atmosphere.
• C5M - Corrosivity category Very High - which is
recommended for marine environment with high salt
load or other aggressive atmosphere.
Colour
Standard colour for Hägglunds motors and accessories is
orange (RAL 2002).

5 DISPLACEMENT SHIFT
Hägglunds CA can be configured with displacement shift
(2-speed). When ordering a motor with displacement shift
the main rotation, clockwise (R) or counter clockwise (L),
has to be specified in the ordering code.
To be used with VTCA valve, see
document: RE 15389
Special index 06 can be used for increased efficiency when
running at higher speed in half displacement, see 9.1:
Special index 06: Motor for high speed at half displacement.
Option 0:
Standard configuration is single speed motor.
Option R:
2-speed motor used for main rotation clockwise (as viewed
from shaft side and inlet to A port).
Option L:
2-speed motor used for main rotation counter-clockwise (as
viewed from shaft side and inlet to A port).
6 TYPE OF SEAL
Option N:
NBR (Nitrile)
Preferred alternative at low ambient tempera-
tures and moderate case oil temperatures.
See section 4.2: General data
Option V:
FPM (Viton)
Preferred alternative at higher case oil temper-
atures, at speed > 280 rpm or when operating with fire
resistant fluids. See section 4.2: General data, 4.13.5: Power
loss freewheeling and 4.5: Hydraulic fluids
Note!
Shift from full to half displacement when motor is
running is allowed up to 30 rpm and when high pressure
is max 150 bar with recommended charge pressure 20
bar. Shift from half to full displacement when motor is
running is not allowed. Running at reversed direction in
half displacement is possible, but must be limited to
210 bar.

11.1.3 Torque arm mounting on plain shaft
Design of driven shaft end on normally loaded shaft
In drives with only one direction of rotation and/or load where
the stresses in the shaft are moderate, the shaft can be plain.
Design of driven shaft end on heavily loaded shaft
Where the driven shaft is heavily loaded and is subject to high
stresses, for example for changes in the direction of rotation
and/or load, it is recommended that the driven shaft should
have a stress relieving groove.

Displacement shift from half to full displacement is not
allowed while the motor is rotating. Shifting from full to
half displacement means that 25% of the pistons are
provided with high pressure and 75% of the pistons are
provided with low pressure. This resulting in twice the
speed and half the torque compared to full displacement.
