Bosch Rexroth R986110052 is a Series 52/53 hydraulic pump engineered as an OEM replacement for CAT 228-3636, delivering compatible fit and consistent 45 cc/rev performance for reliable system operation.
Technical Specifications
Flow Performance
With a 45 cc displacement, the R986110052 provides predictable flow output proportional to shaft speed for stable actuator response and controllable hydraulic power delivery. At speeds up to 2600 RPM, displacement-based flow remains consistent, supporting repeatable machine function under varying load conditions.
Efficiency & Durability
Designed for continuous hydraulic duty at a nominal pressure of 3600 PSI with peak capability to 4600 PSI, the unit maintains performance under high-load transients. Operation up to 2600 RPM supports high cycle rates while preserving stable output within the specified pressure envelope.
Installation
Configured as a direct OEM replacement for CAT 228-3636 in the Rexroth Series 52/53 form factor for straightforward integration. Intended to install without modifications when replacing the original component.
Features and Benefits
- 45 cc displacement: Provides consistent displacement-based flow characteristics for repeatable motion control and predictable hydraulic output.
- 3600 PSI nominal / 4600 PSI peak pressure rating: Supports sustained high-pressure operation with headroom for short-duration peak load events.
- 2600 RPM maximum speed capability: Enables higher operating speeds to meet system flow demand while maintaining controlled performance.
Operational Information
Operate within the specified limits of 3600 PSI nominal pressure, 4600 PSI peak pressure, and up to 2600 RPM to maintain stable performance. Unit weight is approximately 40, supporting robust mechanical stability in typical hydraulic installations.
Quality Assurance
Manufactured to Bosch Rexroth’s stringent quality standards with rigorous testing throughout the production process.

Product Selection Guide
These 52/53 series components share the same nominal pressure rating but differ primarily in displacement and maximum speed capability, which drives flow and operating range.
?? 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 |
|---|---|---|---|---|
| R986110052 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986111125 | 85cc | 3600 PSI | 2500 | 52/53 |
| R986110960 | 60cc | 3600 PSI | 2600 | 52 |
| R986110955 | 60cc | 3600 PSI | 2600 | 52 |
| R986110997 | 110cc | 3600 PSI | 2200 | 31* |
Key Differences
Displacement
R986110052 is 45cc, while the comparison options range from 60cc (R986110960, R986110955) to 85cc (R986111125) and 110cc (R986110997); higher displacement is typically selected when you need more flow per revolution.
Pressure Rating
All listed comparison models show 3600 PSI nominal pressure, matching R986110052’s nominal rating; confirm your system’s required operating and peak pressure align with the component limits.
Speed
R986110052 and the 60cc options list 2600 max speed, the 85cc option lists 2500, and the 110cc option lists 2200; larger displacement options may have lower max speed, which can influence allowable operating RPM.
Quick Selection Guide
Choose: R986110052
Because: When you need a 45cc displacement unit with 3600 PSI nominal pressure, 4600 PSI peak pressure, and up to 2600 max speed in a 52/53 series replacement.
Choose: Higher displacement model
Because: When flow requirements exceed a 45cc displacement, consider 60cc (R986110960 or R986110955), 85cc (R986111125), or 110cc (R986110997), while also checking the listed max speed for the larger sizes.
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, and confirm displacement, pressure ratings, and max speed meet your system requirements.
