Indexing
- Flow: 10 gallons per minute (38 liters per minute)
- Pressure: 1,000 PSI (70 bar)
- Duration: 6 seconds
Press Advance
- Flow: 20 gallons per minute (76 liters per minute)
- Pressure: 500 PSI (35 bar)
- Duration: 2 seconds
Pressing
- Flow: 2 gallons per minute (7.6 liters per minute
- Pressure: 3,000 PSI (210 bar)
- Duration: 10 seconds
Press Retraction
- Flow: 20 gallons per minute (76 liters per minute)
- Pressure: 500 PSI (35 bar)
- Duration: 3 seconds
Part Removal (Index Reverse)
- Flow: 10 gallons per minute (38 liters per minute)
- Pressure: 1,000 PSI (70 bar)
- Duration: 6 seconds

How to Use the Bosch Rexroth Sytronix Size and Select Assistant
Let's review how the Bosch Rexroth Size and Select Tool can help you find the optimal solution for your application.
1. Application Selection & Input Data
To begin, go to the web page and select your application type. Once entered, the tool will have you refine your selection. Select the assembly that aligns most effectively with your requirements.
2. Defining Functions
Next, you will be required to establish various functions for each application step. Our application includes indexing forward, press advance, pressing, press open, and index reverse. Additionally, specifying the necessary flow rates, pressures, and durations for each function is crucial.
3. Analyzing Solutions
Once you have defined the functions, the tool will provide you with various solutions to analyze. It will recommend the most efficient solution based on the parameters you have entered. In the case of the application example mentioned earlier, the software suggests using a 7.5 kW (10 horsepower) motor with a variable frequency drive, paired with a 45 CC pump.
4. Evaluating Utilization
Here, you have the opportunity to analyze the utilization of the motor, drive, and pump components in the recommended solution. In our example, the motor utilization is at an impressive 91%, demonstrating the efficient utilization of available power. The drive utilization represents the average power consumption, while the pump utilization indicates the potential for increased flow.
5. Selecting the Best Solution
Once you have explored the various alternative solutions, Select the best option! For our application, the recommended solution is the best choice. This optimized solution guarantees the utmost utilization while simultaneously conserving energy and reducing costs.
6. Finalizing the Configuration
Once you have selected, complete the configuration process and generate a comprehensive report. This report will provide you with all the necessary details, including specifications, pressure-flow profiles, motor utilization, energy savings, reduction in CO2 emissions, and a detailed bill of materials.
In Summary
In the realm of hydraulic systems, efficiency is paramount for seamless operations. Engineers rely on Bosch Rexroth's Sytronix Size and Select Assistant tool to precisely determine the optimal size for variable-speed hydraulic systems, enhancing their performance, be it a hydraulic pump with a variable frequency drive or a Servo Drive. This blog post reviewed the online tool's features through a practical two-axis press system application guided by hydraulic expert Rob Panzarella, showcasing how to accurately size, select, and order hydraulic motor pumps with the Sytronix Size and Select Assistant.
