Installation and Maintenance Manual, Compact CBP 

1.3  Functional description

Fig. 1  The COMPACT CBP 140

Hägglunds  hydraulic  industrial  motor  COM-
PACT 

CBP  is  of  the  radial-piston  type  with 

a  rotating  cylinder  block/hollow  shaft  and  a 
stationary housing. The cylinder block is moun-
ted in fixed roller bearings in the housing. An 
even number of pistons are radially located in 
bores inside the cylinder block, and two valve 
plate 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 
piston which are guided in the rotating 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 connection blocks and drain lines to ports 
D1, D, D or D4 

 

in the motor housing.

The  motor  is  connected  to  the  shaft  of  the 
driven  machine  through  the  hollow  shaft  of 
the  cylinder  block.The  torque  is  transmitted 
by splines.
