Bosch Rexroth R986111376 (Series 52/53) is a direct OEM replacement for CAT 355-2394, built to deliver reliable hydraulic performance with proven compatibility in the original installation envelope.
Technical Specifications
Flow Performance
With a 100 cc displacement, the R986111376 supports strong per-revolution output for consistent actuator response and predictable machine control. Stable displacement behavior helps maintain repeatable flow characteristics across operating speeds up to 2300 RPM.
Efficiency & Durability
Rated for 3600 PSI nominal pressure with 4600 PSI peak capability, this unit is designed to sustain performance under demanding load conditions. The 2300 RPM maximum speed supports responsive operation while maintaining durability under continuous duty pressure cycles.
Installation
Engineered as an OEM form-and-fit replacement for CAT 355-2394, the R986111376 installs as a direct replacement with no modifications required. OEM-matching interface expectations support straightforward mounting and hydraulic line integration.
Features and Benefits
- 100 cc displacement: Delivers consistent per-revolution output to support predictable flow and repeatable machine response.
- 3600 PSI nominal / 4600 PSI peak pressure rating: Maintains hydraulic performance under high load and transient pressure spikes within rated limits.
- 2300 RPM maximum speed capability: Supports fast cycle response and stable operation across a wide operating speed range up to 2300 RPM.
Operational Information
Designed for operation within rated pressure limits (3600 PSI nominal, 4600 PSI peak) and speeds up to 2300 RPM to maintain reliable hydraulic output. Proper system filtration and adherence to rated conditions help sustain consistent performance over time.
Quality Assurance
Manufactured to Bosch Rexroth’s stringent quality standards with rigorous testing throughout the production process.

Product Selection Guide
Compare these Series 52/53 components primarily by displacement (flow per revolution) and allowable speed, since the listed nominal pressure rating is the same across the compared part numbers. If you’re still narrowing down options, browse our hydraulic pumps selection for related configurations.
?? 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 |
|---|---|---|---|---|
| R986111376 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986110631 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986110671 | 72cc | 3600 PSI | 2600 | 52/53* |
| R986110609 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986111102 | 74cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986111376 is 100cc, while the comparison parts are 71–74cc; choose 100cc when your system requires higher flow per revolution, and choose 71–74cc when the existing system is designed around a smaller displacement.
Pressure Rating
All compared models list 3600 PSI nominal pressure; however, R986111376 also specifies a 4600 PSI peak pressure rating, so confirm your duty cycle and peak events align with the pump’s stated limits.
Speed
R986111376 lists 2300 max speed, while the comparison parts list 2600; select the model that meets or exceeds your required operating speed range. For similar axial designs, see our piston pumps lineup.
Quick Selection Guide
Choose: R986111376
Because: When you need a Series 52/53 unit with 100cc displacement, 3600 PSI nominal pressure, 4600 PSI peak pressure capability, and a max speed of 2300.
Choose: Higher displacement model
Because: When flow requirements exceed what a 71–74cc option can provide and your system is designed for a larger displacement.
Choose: Lower pressure model
Because: When system operates at lower pressures for cost savings.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation. If you’re comparing adjacent build options, R986111250 may be a relevant cross-check depending on your OEM reference and control setup.
