Bosch Rexroth R986111455 (Series 52/53) is a direct OEM replacement for CAT 460-4904, delivering consistent 100 cc displacement performance with reliable compatibility in demanding hydraulic duty cycles.
Technical Specifications
Flow Performance
With a 100 cc displacement, the R986111455 provides predictable volumetric output per revolution to support stable actuator and drive response. Rated for speeds up to 2300 RPM, it maintains consistent flow delivery across the operating range when properly supplied and controlled.
Efficiency & Durability
Designed for continuous hydraulic loading at 3600 PSI nominal pressure with capability up to 4600 PSI peak, the unit supports high-force operation without sacrificing stability. The 2300 RPM maximum speed rating helps sustain performance under dynamic conditions where rapid response and repeatable output are required.
Installation
Built as an OEM-form replacement for CAT 460-4904, the R986111455 is intended to install as a direct replacement with no modifications. Standard fitment supports straightforward mounting and integration into the existing hydraulic circuit.
Features and Benefits
- 100 cc displacement: Delivers a fixed 100 cc per revolution output for repeatable flow behavior and predictable machine response.
- 3600 PSI nominal / 4600 PSI peak pressure capability: Supports continuous operation at 3600 PSI with headroom to 4600 PSI peak for transient load events.
- 2300 RPM maximum speed rating: Enables high-speed operation up to 2300 RPM to maintain required flow delivery during fast cycle demands.
Operational Information
Operate within the specified 3600 PSI nominal and 4600 PSI peak pressure limits and up to 2300 RPM to maintain consistent output and service life. With a 75 lb component mass, ensure secure mounting and proper system support to maintain reliability under vibration and load.
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 span multiple displacements at the same nominal pressure rating, with speed limits that vary by size—use displacement and max speed to match flow and duty 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 |
|---|---|---|---|---|
| R986111455 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986110070 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986111102 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986110062 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986110630 | 100cc | 3600 PSI | 2300 | 52/53 |
Key Differences
Displacement
R986111455 and R986110630 are 100cc options for higher flow per revolution, while R986111102 (74cc), R986110062 (71cc), and R986110070 (45cc) reduce flow per revolution for smaller circuit demand or finer control.
Pressure Rating
All listed comparison models show 3600 PSI nominal pressure; R986111455 additionally specifies 4600 PSI peak pressure, which matters if your system experiences short-duration pressure spikes.
Speed
R986111455 and R986110630 are rated to 2300 max speed, while the smaller-displacement alternatives list 2600 max speed—select based on your prime mover RPM and required operating speed range.
Quick Selection Guide
Choose: R986111455
Because: When you need 100cc displacement with 3600 PSI nominal pressure, 4600 PSI peak capability, and a 2300 max speed limit in a 52/53 series replacement.
Choose: R986110630
Because: When you need the same 100cc displacement, 3600 PSI nominal pressure, and 2300 max speed as the current unit, but are comparing alternate 52/53 part numbers.
Choose: R986111102 / R986110062 / R986110070
Because: When your system flow requirement is lower and you prefer a smaller displacement (74cc, 71cc, or 45cc respectively) while maintaining a 3600 PSI nominal pressure rating and up to 2600 max speed.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation. If you’re comparing similar piston pumps, confirm control type and case drain requirements as well.
