Product Selection Guide
These Bosch Rexroth Series 52/53 components share a 3600 PSI nominal pressure class, so selection typically comes down to matching displacement (flow) and allowable speed to your existing setup.
?? 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 |
|---|---|---|---|---|
| R986111098 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986111478 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986110071 | 28cc | 3600 PSI | 3000 | 52/53 |
| R986110063 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986111250 | 45cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986111098 is 71cc; alternatives range from 28cc (R986110071) and 45cc (R986111250) for lower flow needs, to 74cc (R986110063) for a close match, and 100cc (R986111478) when higher flow per revolution is required.
Pressure Rating
All listed comparison models are rated at 3600 PSI nominal; R986111098 also specifies a 4600 PSI peak rating, so confirm your duty cycle and peak events align with the replacement part’s documented limits.
Speed
Maximum speed varies by model: R986111098 and R986110063 and R986111250 are 2600 max, R986111478 is 2300, and R986110071 is 3000—match the replacement to your prime mover and operating RPM range.
Quick Selection Guide
Choose: R986111098
Because: When you need a 71cc displacement with 3600 PSI nominal pressure, 4600 PSI peak capability, and up to 2600 max speed in a Series 52/53 replacement.
Choose: Higher displacement model
Because: Choose R986111478 (100cc) when your required flow per revolution is higher than a 71cc unit can provide, and your operating speed is within its 2300 max speed limit.
Choose: Lower displacement model
Because: Choose R986110071 (28cc) or R986111250 (45cc) when your system requires lower flow per revolution while maintaining a 3600 PSI nominal pressure rating, and match to the appropriate max speed (3000 for 28cc; 2600 for 45cc).
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation.
