Technical Specifications
Flow Performance
With a 100 cc displacement, R986110684 provides predictable output per revolution for consistent system response under load. The displacement supports stable flow characteristics across operating speeds up to 2300 max, helping maintain controllable actuator and circuit performance.
Efficiency & Durability
Rated for 3600 PSI nominal pressure and 4600 PSI peak pressure, this component is designed to sustain performance in high-pressure duty cycles. Operation up to 2300 max speed supports demanding hydraulic power requirements while maintaining consistent output within its specified operating limits.
Installation
Designed as a direct OEM replacement for CAT 397-3970, R986110684 is intended to match the existing interface for straightforward installation. It is built for OEM-fit replacement without modifications when installed in the corresponding CAT configuration.
Features and Benefits
- 100 cc displacement: Delivers consistent volumetric output per revolution to support stable flow and repeatable machine response.
- 3600 PSI nominal / 4600 PSI peak pressure capability: Supports high-pressure operation, including transient peak events up to 4600 PSI within specified limits.
- 2300 max speed rating: Enables dependable performance at higher operating speeds up to 2300 max to meet demanding cycle requirements.
Operational Information
Built for operation within the specified 3600 PSI nominal and 4600 PSI peak pressure limits and up to 2300 max speed. The 75 weight and Series 52/53 configuration support robust service in continuous-duty hydraulic environments when operated within rated conditions.
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 rating, so selection is primarily driven by displacement (flow) needs and allowable operating speed for your duty cycle.
?? 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 |
|---|---|---|---|---|
| R986110684 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986111315 | 60cc | 3600 PSI | 2600 | 52 |
| R986110100 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986110091 | 140cc | 3600 PSI | 2000 | 31* |
| R986111199 | 110cc | 3600 PSI | 2200 | 31* |
Key Differences
Displacement
R986110684 is 100cc; smaller options (R986111315 at 60cc, R986110100 at 71cc) suit lower flow requirements, while larger options (R986111199 at 110cc, R986110091 at 140cc) are better when higher flow per revolution is needed.
Pressure Rating
All listed comparators are rated at 3600 PSI nominal; R986110684 also specifies a 4600 PSI peak rating, so confirm your system’s peak pressure demands align with the part selected.
Speed
Maximum speed varies across the group (R986110684: 2300; 60cc/71cc options: 2600; 110cc: 2200; 140cc: 2000), so choose a model that meets your required operating RPM without exceeding its limit.
Quick Selection Guide
Choose: R986110684
Because: When you need a 100cc displacement with 3600 PSI nominal pressure capability and up to 2300 max speed, with a specified 4600 PSI peak rating.
Choose: Higher displacement model
Because: When your flow requirements exceed a 100cc displacement—consider R986111199 (110cc) or R986110091 (140cc)—and ensure your required operating speed is within their listed max speeds (2200 and 2000, respectively).
Choose: Lower displacement model
Because: When you need reduced flow per revolution and/or higher maximum speed—consider R986111315 (60cc) or R986110100 (71cc), both listed at 2600 max speed with 3600 PSI nominal pressure.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation, and confirm displacement, pressure, and maximum speed align with your system requirements.
