Bosch Rexroth R986110077 (Series 52/53) is a direct OEM replacement for CAT 293-9611, engineered for reliable compatibility and consistent hydraulic performance in the same footprint.
Technical Specifications
Flow Performance
With a 45 cc displacement, the R986110077 delivers predictable output per revolution for stable actuator response and repeatable machine control. Flow scales directly with speed up to 2600 RPM, supporting consistent hydraulic delivery across the operating range.
Efficiency & Durability
Rated for 3600 PSI nominal pressure with 4600 PSI peak capability, the unit is built to maintain performance under high-load transients without compromising system stability. Operation up to 2600 RPM supports sustained duty while preserving pressure capability within the specified limits.
Installation
Designed as an OEM-form, fit, and function replacement for CAT 293-9611, supporting direct installation with standard mounting interfaces. It is intended to install without modifications when replacing the original component.
Features and Benefits
- 45 cc displacement: Provides consistent displacement per revolution for repeatable flow output and predictable hydraulic response.
- 3600 PSI nominal / 4600 PSI peak pressure rating: Supports high working pressure with defined peak headroom for transient load events.
- 2600 RPM maximum speed: Enables higher operating speed capability for maintaining required flow as system demand varies.
Operational Information
Operate within the specified limits of 3600 PSI nominal (4600 PSI peak) and up to 2600 RPM to maintain stable performance. Proper system filtration and fluid condition are expected to support long-term reliability consistent with Series 52/53 operation.
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 share a 3600 PSI nominal pressure class, so selection is primarily driven by displacement (flow per revolution) and allowable speed for your system requirements.
?? 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 |
|---|---|---|---|---|
| R986110077 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986111125 | 85cc | 3600 PSI | 2500 | 52/53 |
| R986110049 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986110119 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986110045 | 28cc | 3600 PSI | 3000 | 52/53 |
Key Differences
Displacement
R986110077 and R986110049 are 45cc options for matching an existing 45cc setup; R986110045 (28cc) suits lower flow needs, while R986110119 (71cc) and R986111125 (85cc) support higher flow requirements at the same nominal pressure rating.
Pressure Rating
All compared models list 3600 PSI nominal pressure; R986110077 additionally specifies a 4600 PSI peak pressure, so confirm peak-pressure requirements when substituting other part numbers.
Speed
Maximum speed varies by model: R986110077/R986110049/R986110119 are rated 2600, R986111125 is 2500, and R986110045 is 3000—choose a model that meets or exceeds your operating speed.
Quick Selection Guide
Choose: R986110077
Because: When you need a Series 52/53, 45cc displacement unit with 3600 PSI nominal pressure, 4600 PSI peak pressure, and up to 2600 max speed.
Choose: Higher displacement model (R986110119 71cc or R986111125 85cc)
Because: When your system requires more flow per revolution than a 45cc unit while staying in the 3600 PSI nominal pressure class (verify the lower max speed of 2500 on R986111125 if speed is critical).
Choose: Lower displacement model (R986110045 28cc)
Because: When you need reduced flow per revolution and/or higher allowable speed (up to 3000) compared with 45cc options, while maintaining a 3600 PSI nominal pressure rating.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation, and confirm nominal/peak pressure and maximum speed requirements align with your system.
