Bosch Rexroth R986110112 is a Series 52/53 hydraulic unit engineered as an OEM replacement for CAT 122-1206, providing direct-fit compatibility with consistent 45 cc displacement performance.
Technical Specifications
Flow Performance
With a 45 cc displacement, R986110112 delivers predictable volumetric output per revolution for stable actuator response and controllable machine motion. At speeds up to 2600 rpm, it supports high-cycle operation while maintaining repeatable flow characteristics within the component’s rated operating envelope.
Efficiency & Durability
Rated for 3600 psi nominal pressure and 4600 psi peak pressure, the unit is built to sustain demanding hydraulic loads without exceeding specified limits. Its Series 52/53 design supports operation up to 2600 rpm, helping maintain performance consistency across varying duty cycles and pressure transients.
Installation
Designed as a direct OEM replacement for CAT 122-1206, R986110112 matches the intended Series 52/53 form factor for straightforward installation. It is intended to install without modifications when replacing the specified OEM component.
Features and Benefits
- 45 cc displacement: Provides consistent displacement per revolution to support repeatable flow delivery and predictable system response.
- 3600 psi nominal / 4600 psi peak pressure capability: Supports continuous operation at 3600 psi with headroom for short-duration pressure spikes up to 4600 psi.
- 2600 rpm maximum speed rating: Enables high-speed operation up to 2600 rpm for responsive hydraulic performance across fast duty cycles.
Operational Information
Operate within the specified 3600 psi nominal and 4600 psi peak pressure limits and do not exceed 2600 rpm maximum speed. The 40 lb component mass supports stable mounting in OEM configurations and reliable operation when installed per the machine’s original hydraulic layout.
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 the same nominal pressure and max speed, so selection is primarily driven by displacement (flow per revolution) and matching the exact replacement part number. If you’re comparing similar piston pumps, confirm the control type and configuration match your existing circuit.
?? 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 |
|---|---|---|---|---|
| R986110112 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986111395 | 60cc | 3600 PSI | 2600 | 52 |
| R986111411 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986111064 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986110936 | 74cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986110112 and R986111411 are 45cc options for matching existing 45cc flow characteristics, while R986111395 (60cc) and R986111064/R986110936 (74cc) increase flow per revolution for higher flow demand at the same speed.
Pressure Rating
All compared models list 3600 PSI nominal pressure, so pressure rating is not a differentiator here; ensure your system requirements align with the current product’s 3600 PSI nominal and 4600 PSI peak capability.
Speed
All compared models list 2600 max speed, so speed does not materially differentiate these options; selection should focus on displacement and configuration matching.
Quick Selection Guide
Choose: R986110112
Because: When you need a Series 52/53 45cc unit with 3600 PSI nominal pressure, 4600 PSI peak pressure, and 2600 max speed to match the current specification.
Choose: Higher displacement model
Because: When flow requirements exceed a 45cc displacement at the same 2600 max speed—consider 60cc (R986111395) or 74cc (R986111064 / R986110936) to increase flow per revolution while keeping the same listed nominal pressure and max speed. For additional options within the same family, you can also compare R986111250 for fit and configuration.
Choose: Lower pressure model
Because: Not applicable within this comparison set, since all listed alternatives have the same 3600 PSI nominal pressure; choose a lower-pressure-rated option only if your system operates at lower pressures and the replacement part’s rated pressure matches your requirement.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation, and confirm displacement, nominal/peak pressure requirements, and max speed align with your system.
