Product Selection Guide
These Bosch Rexroth 31* components share the same 3600 PSI nominal pressure class, so selection is primarily driven by required displacement (flow) and allowable operating speed.
?? Important: The specifications shown are for reference and comparison purposes. Always verify specifications with the official manufacturer documentation or contact our technical team before ordering to ensure compatibility with your application.
| Part Number | Displacement | Pressure | Max Speed | Series |
|---|---|---|---|---|
| R986111283 | 110cc | 3600 PSI | 2200 | 31* |
| R986111503 | 85cc | 3600 PSI | 2500 | 52/53 |
| R986110074 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986110574 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986110088 | 45cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986111283 is 110cc, higher than the compared 100cc, 85cc, 71cc, and 45cc options; choose higher displacement when you need more flow per revolution, and lower displacement when you can meet flow needs with higher speed or want finer control at lower flow.
Pressure Rating
All listed comparison models show 3600 PSI pressure, matching the nominal pressure of R986111283; if your duty cycle requires operating beyond nominal, confirm suitability against the peak pressure requirement of your system.
Speed
R986111283 is rated to 2200 max speed, while the comparison models range from 2300 to 2600; choose the higher-speed options when your application requires higher RPM capability within the same nominal pressure class.
Quick Selection Guide
Choose: R986111283
Because: When you need 110cc displacement with 3600 PSI nominal pressure, up to 4600 PSI peak pressure, and a 2200 max speed rating.
Choose: R986110574
Because: When you want a similar pressure class (3600 PSI) but slightly lower displacement (100cc) and a higher max speed rating (2300) than R986111283.
Choose: R986111503 / R986110074 / R986110088
Because: When your flow requirement is lower and you prefer smaller displacement options (85cc, 71cc, or 45cc) with higher max speed ratings (2500–2600) while staying in the 3600 PSI nominal pressure class.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation, and confirm displacement, pressure (nominal/peak), and max speed align with your system requirements.
