Series 52 design supports efficient power transfer at working pressures up to 3600 PSI, helping control operating cost while maintaining predictable performance.
Efficiency & Durability
Rated for 3600 PSI nominal pressure and 4600 PSI peak pressure, this component is built to sustain demanding load cycles without sacrificing performance. It supports speeds up to 2600, maintaining dependable operation across typical duty conditions while helping limit downtime through robust pressure capability.
Installation
Engineered as an OEM-fit replacement for CAT 316-8366, the R986110955 matches the required interface for straightforward installation. It is intended as a direct replacement with no modifications required.
Features and Benefits
- 60 cc displacement: Delivers predictable displacement-based flow for stable machine response and repeatable cycle performance.
- 3600 PSI nominal / 4600 PSI peak pressure capability: Supports high-load operation with defined pressure margins for transient spikes and demanding duty cycles.
- 2600 max speed capability: Enables reliable operation at higher rotational speeds to maintain output across varying operating conditions.
Operational Information
Operate within the stated pressure limits (3600 PSI nominal, 4600 PSI peak) and up to 2600 speed to maintain consistent performance. Designed for dependable service in standard hydraulic operating environments where stable output and controlled operating cost are priorities.
Quality Assurance
Manufactured to Bosch Rexroth’s stringent quality standards with rigorous testing throughout the production process.

Compatibility & Applications
Direct Replacement Information
This Bosch Rexroth R986110955 replaces CAT 316-8366 in high-pressure closed-loop and open-circuit hydraulic drive applications.
- Hydrostatic circuits requiring 60cc/rev displacement variable flow control
- Systems operating at 3600 PSI nominal pressure with variable displacement demand
- Mobile and industrial axial piston variable pump circuits up to 2600 RPM max input speed
Common Applications
This Bosch Rexroth R986110955 is commonly used in:
- construction and earthmoving equipment hydraulic drive systems
- material handling machinery (lift, propel, and auxiliary hydraulics)
- industrial machinery power units and process equipment hydraulics
Important: Verify mounting interface, shaft type, rotation, controls, and port configuration match the existing CAT 316-8366 installation before ordering.
Product Selection Guide
Within Series 52, R986110955 (60cc) sits between smaller 28cc and larger 71cc displacement options, with comparable nominal pressure and similar max speed to most listed alternatives. If you are comparing hydraulic pumps across equipment platforms, displacement and control type are typically the quickest way to narrow down fitment.
?? 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 |
|---|---|---|---|---|
| R986110955 | 60cc | 3600 PSI | 2600 | 52 |
| R986110631 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986110071 | 28cc | 3600 PSI | 3000 | 52/53 |
| R986110068 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986110099 | 45cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
Displacement varies from 28cc (R986110071) to 71cc (R986110631), with 45cc options (R986110068/R986110099) and the current 60cc (R986110955) in between; higher displacement is typically chosen when more flow is needed at a given speed, while lower displacement is used when lower flow is acceptable or desired.
Pressure Rating
All compared models list 3600 PSI pressure, while R986110955 additionally specifies a 4600 PSI peak pressure; match your system’s required nominal pressure and confirm any peak/overload requirements against the component rating.
Speed
Most listed models show 2600 max speed (including R986110955), while R986110071 lists 3000; select based on the required operating speed range and ensure the component’s max speed meets or exceeds your application needs.
Quick Selection Guide
Choose: R986110955
Because: When you need Series 52 with 60cc displacement, 3600 PSI nominal pressure, up to 4600 PSI peak pressure, and 2600 max speed.
Choose: Higher displacement model
Because: When flow requirements exceed a 60cc displacement—consider R986110631 (71cc) if the 3600 PSI pressure and 2600 speed align with your system.
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. For similar piston pumps, also confirm control configuration and case drain routing to avoid startup and heat issues.
