Bosch Rexroth Hydraulic Industrial Motor Hägglunds CA CA50 CA70 CA100 CA140 CA210

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 pistens are radially located in bores inside the cylinder block, and the distributor directs the incoming and outgoing oil to and from the working pistens. Each piston is working against a cam roller. When the hydraulic pressure is acting on the pistens, 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 connection housing and drain lines to one of the D -ports in the motor housing. The motor is connected to the shaft of the driven machine through the hollow shaft or spline of the cylinder block. The symmetrical design of the motor has made it possible to design it as a dual displacement motor. This means that two different displacements and speeds can be obtained for a given flow. To get the 2-speed function, a motor prepared for two speeds has to be ordered together with a 2-speed valve.
