303 series
Variable displacement axial piston bent-axis hydraulic motors
Purpose:
Hydraulic motors convert the working fluid energy into the shaft rotation mechanical energy.
Hydraulic motors are intended for operation in open and close loops of stationary and mobile installations.
Working displacement: 28, 55, 56, 80, 107, 112, 160, 250 ccm/rev
