The SYDFE1-2X/018R-VKC62N00-0000-A0X0XXX SO43A-1834 hydraulic control unit is produced by Bosch Rexroth within the SYD Hydraulic Control Systems series. It regulates pump displacement and pressure in automated hydraulic circuits. The unit has a displacement of 18 cm3 and turns clockwise, making it compatible with right-hand shaft couplings. A housing filling quantity of 0.4 l provides the initial oil volume for commissioning. It accepts mineral oil classified as HL or HLP, ensuring lubrication and sealing of internal components. The nominal flow reaches 59.4 l/min at maximum geometric volume, supporting medium flow applications. Operating pressure can be set up to 280 bar, and under that pressure the device delivers 27.7 kW. The control electronics respond to a 0 to 10 V pressure command and a ±10 V swivel angle signal to adjust output in closed-loop systems.
The assembly weighs 15.5 kg without a through-drive which simplifies mounting on compact power units. Shaft loading permits 700 N axial and 350 N radial force, allowing direct coupling to gear sets or pulleys. Maximum speed is 3300 rpm when running at full displacement, yet the mechanism can work down to 250 rpm for low-flow tasks. Peak torque reaches 80.1 Nm at 280 bar, and the drive axis moment of inertia is limited to 0.0009 kg·m² to minimize start-up energy. These characteristics enable precise, efficient hydraulic power modulation within industrial automation platforms.
