Bosch Rexroth R986111408 is a Series 52/53* hydraulic unit engineered as an OEM replacement for CAT 587-0008, delivering reliable, compatible performance with matched operating characteristics.
Technical Specifications
Flow Performance
With a 72 cc displacement, the R986111408 provides consistent volumetric output per revolution for predictable actuator and motor response. Performance is maintained up to a maximum speed of 2600, supporting stable flow delivery across demanding duty cycles.
Efficiency & Durability
Rated for 3600 PSI nominal pressure and 4600 PSI peak pressure, this unit is built to sustain high-load hydraulic operation without sacrificing performance. Its 2600 maximum speed capability helps maintain responsive system behavior while operating within specified pressure limits.
Installation
Designed as a direct replacement for CAT 587-0008, the R986111408 is intended to match OEM fit and interface requirements. Installation is straightforward and does not require modifications when replacing the original component in the same configuration.
Features and Benefits
- 72 cc displacement: Delivers predictable output per revolution to support consistent machine response and controllable hydraulic performance.
- 3600 PSI nominal / 4600 PSI peak pressure capability: Supports high working pressures with headroom for peak events, helping maintain performance during transient load spikes.
- 2600 maximum speed rating: Enables higher operating speed capability for responsive flow delivery within the specified operating envelope.
Operational Information
Operate within the stated 3600 PSI nominal and 4600 PSI peak pressure limits and up to 2600 speed to maintain consistent performance. The 48.5 weight reflects a robust build suited to sustained hydraulic duty in typical industrial and mobile operating environments.
Quality Assurance
Manufactured to Bosch Rexroth’s stringent quality standards with rigorous testing throughout the production process.

Compatibility & Applications
Direct Replacement Information
This Rexroth R986111408 replaces CAT 587-0008 in high-pressure mobile and industrial hydraulic system applications.
- Closed-loop or open-loop hydraulic circuits requiring 72cc variable displacement flow control
- Hydraulic systems operating at 3600 PSI nominal pressure with demand-based output regulation
- Pump drives up to 2600 RPM where variable-flow axial piston pump control is required for actuators or hydraulic motors
Common Applications
This Bosch Rexroth R986111408 is commonly used in:
- construction and earthmoving equipment hydraulic pumps and drive circuits
- material handling and lifting equipment hydraulics
- industrial power units for presses, clamps, and high-force actuation
- process machinery and general industrial hydraulics requiring variable flow
Important: Verify mounting interface, shaft configuration, rotation, control type, and port locations match the existing CAT 587-0008 installation before ordering.
Product Selection Guide
These 52/53* components are best compared by matching displacement (cc/rev) and maximum speed while keeping the same 3600 PSI nominal pressure requirement.
?? 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 |
|---|---|---|---|---|
| R986111408 | 72cc | 3600 PSI | 2600 | 52/53* |
| R986110606 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986110675 | 72cc | 3600 PSI | 2600 | 52/53* |
| R986110936 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986110804 | 74cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986111408 is 72cc, matching R986110675 (72cc) most closely; R986110936 and R986110804 are slightly higher at 74cc, and R986110606 is higher at 100cc—choose higher displacement when you need more flow per revolution without changing drive speed.
Pressure Rating
All listed comparison models show 3600 PSI pressure, aligning with R986111408’s 3600 PSI nominal rating; ensure your system does not exceed the component’s rated limits and note that peak pressure capability is not provided for the comparison items.
Speed
R986111408 is rated to 2600 max speed, matching R986110675, R986110936, and R986110804 (2600), while R986110606 is lower at 2300—select a 2600-rated option when your duty cycle requires higher operating speed.
Quick Selection Guide
Choose: R986111408
Because: When you need a 72cc displacement with 3600 PSI nominal pressure capability and up to 2600 max speed in the 52/53* series.
Choose: Higher displacement model
Because: When your required flow per revolution is higher than 72cc (e.g., 74cc options R986110936/R986110804 or 100cc option R986110606), while still maintaining a 3600 PSI nominal pressure requirement.
Choose: Lower pressure model
Because: Not applicable from the models listed, since all provided comparison options are rated at 3600 PSI nominal.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation. For similar piston pumps and related options, review our pump selection pages or contact our team.
