Bosch Rexroth R986110090 (Series 52/53) is an OEM replacement for CAT 232-1835, delivering reliable hydraulic performance with direct-fit compatibility and consistent output under rated pressures.
Technical Specifications
Flow Performance
With a 71 cc displacement, the R986110090 provides predictable volumetric output per revolution for stable actuator response and controllable machine movement. Performance is maintained across its operating range up to 2600 max speed, supporting responsive flow delivery as system demand changes.
Efficiency & Durability
Rated for 3600 PSI nominal pressure with 4600 PSI peak capability, this unit is built to sustain performance under high-load hydraulic conditions. Operation up to 2600 max speed supports consistent output while helping maintain stable performance across varying duty cycles.
Installation
Designed as a direct OEM replacement for CAT 232-1835, the R986110090 installs with OEM-fit compatibility. It is intended to mount in place without modifications when replacing the original component.
Features and Benefits
- 71 cc displacement: Delivers consistent volume per revolution for predictable machine response and controllable hydraulic output.
- 3600 PSI nominal / 4600 PSI peak pressure rating: Supports high-load operation with headroom for short-duration pressure spikes within the specified peak rating.
- 2600 max speed capability: Maintains responsive hydraulic performance at higher operating speeds for demanding duty cycles.
Operational Information
Operate within the specified 3600 PSI nominal and 4600 PSI peak pressure limits and up to 2600 max speed to maintain stable performance. The 48.5 weight and Series 52/53 design support reliable operation when used within rated conditions.
Quality Assurance
Manufactured to Bosch Rexroth’s stringent quality standards with rigorous testing throughout the production process.

Product Selection Guide
These Series 52/53 components are best compared by displacement (flow per rev) since the listed pressure (3600 PSI nominal) and speed (2600 max) are consistent across the similar part numbers provided. If you’re comparing other hydraulic pumps, displacement and control type are typically the fastest way to narrow down compatible options.
?? 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 |
|---|---|---|---|---|
| R986110090 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986110113 | 60cc | 3600 PSI | 2600 | 52 |
| R986110106 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986111581 | 60cc | 3600 PSI | 2600 | 52 |
| R986110632 | 74cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986110090 is 71cc; comparable options include 60cc (R986110113, R986111581) for lower flow per revolution and 74cc (R986110632) for slightly higher flow—choose based on required flow and how much speed you can run to achieve it.
Pressure Rating
The similar products listed all show 3600 PSI; R986110090 is rated 3600 PSI nominal with 4600 PSI peak—verify your system’s required nominal and peak pressures match the part you select.
Speed
All compared models list 2600 max speed, so selection is typically driven more by displacement and pressure requirements than by speed capability.
Quick Selection Guide
Choose: R986110090
Because: When you need 71cc displacement with 3600 PSI nominal pressure capability, 4600 PSI peak capacity, and up to 2600 max speed in a Series 52/53 replacement.
Choose: Higher displacement model
Because: When flow requirements exceed what a 71cc unit can deliver at your available operating speed—consider the 74cc option (R986110632) if the rest of the configuration matches.
Choose: Lower pressure model
Because: When the system operates at lower pressures—selecting a lower-rated unit is only appropriate if its pressure rating still meets your system requirements (no lower-pressure alternatives are listed here, so confirm before substituting).
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation. If you’re sourcing similar axial units, browse our piston pumps selection to compare configurations and displacements.
