Bosch Rexroth R986110048 (Series 52) is a direct OEM replacement for CAT 229-0099, delivering reliable, compatible hydraulic performance with a cost-effective approach to maintaining original machine function.
Technical Specifications
Flow Performance
With a 60 cc displacement, the R986110048 provides consistent, predictable output per revolution to support stable hydraulic response. Rated for up to 2600 max speed, it is suited for maintaining flow capability across typical operating speeds while supporting cost-effective system uptime.
Efficiency & Durability
Designed for demanding duty, it operates at 3600 PSI nominal pressure with 4600 PSI peak capability to handle load changes without sacrificing performance. The 2600 max speed rating supports sustained operation, helping maintain consistent hydraulic behavior over time.
Installation
Engineered as an OEM-fit replacement for CAT 229-0099, this Series 52 unit is intended to install as a direct replacement with no modifications. Standard mounting and connection expectations align with the original component footprint.
Features and Benefits
- 60 cc displacement: Delivers consistent output per revolution for stable actuator and circuit response.
- 3600 PSI nominal / 4600 PSI peak pressure rating: Supports continuous working loads and manages short-duration pressure spikes without changing the component.
- 2600 max speed capability: Maintains reliable operation across a wide speed range to support consistent hydraulic performance.
Operational Information
Operate within the stated 3600 PSI nominal and 4600 PSI peak pressure limits and up to 2600 max speed to maintain expected reliability. The 48.5 weight reflects a robust build suited for steady hydraulic service under normal system operating conditions.
Quality Assurance
Manufactured to Bosch Rexroth’s stringent quality standards with rigorous testing throughout the production process.

Product Selection Guide
These Series 52 components share a 3600 PSI nominal pressure rating, with selection primarily driven by displacement (flow) and allowable operating speed for hydraulic pumps.
?? 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 |
|---|---|---|---|---|
| R986110048 | 60cc | 3600 PSI | 2600 | 52 |
| R986111332 | 63cc | 3600 PSI | 2600 | 53 |

| R986111478 | 100cc | 3600 PSI | 2300 | 52/53 |
Key Differences
Displacement
R986110048 is 60cc, closest to R986111332 at 63cc for near-like-for-like flow; R986111478 (100cc), R986111123 (110cc), and R986111454 (280cc) step up flow capacity for higher output requirements.
Pressure Rating
All listed comparison models show 3600 PSI nominal pressure; R986110048 also specifies 4600 PSI peak pressure, which should be matched to your system’s transient/peak demands.
Speed
R986110048 and R986111332 list 2600 max speed, while higher-displacement options list lower max speeds where provided (2200 for R986111123 and 2300 for R986111478); R986111454 speed is not provided and must be verified before substituting.
Quick Selection Guide
Choose: R986110048
Because: When you need 60cc displacement with 3600 PSI nominal pressure, 4600 PSI peak pressure, and up to 2600 max speed in a Series 52 replacement.
Choose: Higher displacement model
Because: When flow requirements exceed 60cc—consider R986111478 (100cc), R986111123 (110cc), or R986111454 (280cc), while confirming the listed max speed meets your operating range.
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. If you’re comparing similar piston pumps, confirm control type and rotation as well.
