Bosch Rexroth R986110806 (Series 31*) is a reliable OEM replacement for CAT 416-8986, built to maintain OEM-fit compatibility and consistent hydraulic performance under demanding duty cycles.
Technical Specifications
Flow Performance
With a 110 cc displacement, the R986110806 delivers stable, predictable output per revolution for consistent actuator response. Its design supports dependable flow performance up to a maximum speed of 2200 rpm, helping maintain steady system behavior in continuous operation.
Efficiency & Durability
Rated for 3600 PSI nominal pressure and 4600 PSI peak pressure, this unit is engineered to sustain performance through high-load events without compromising operational stability. Reliable operation is maintained across its speed capability up to 2200 rpm, supporting consistent hydraulic output under variable demand.
Installation
Configured as a direct OEM replacement for CAT 416-8986 for straightforward integration and OEM-fit alignment. Installs without modifications when replacing the original component in the same mounting location.
Features and Benefits
- 110 cc displacement: Provides consistent volumetric output per revolution for predictable hydraulic response.
- 3600 PSI nominal / 4600 PSI peak pressure capability: Supports sustained high-pressure operation and tolerates short peak events to help prevent performance drop during load spikes.
- 2200 rpm maximum speed: Maintains dependable flow capability across operating speeds up to 2200 rpm for stable system performance.
Operational Information
Designed for reliable operation in hydraulic systems up to 3600 PSI nominal and 4600 PSI peak, with rotational speeds up to 2200 rpm. Operating conditions should remain within the host system’s established limits to preserve consistent performance.
Quality Assurance
Manufactured to Bosch Rexroth’s stringent quality standards with rigorous testing throughout the production process.

Product Selection Guide
Within the 31* series, these part numbers primarily differ by displacement and allowable speed while maintaining the same nominal pressure rating, so selection is driven by required flow and operating RPM.
?? 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 |
|---|---|---|---|---|
| R986110806 | 110cc | 3600 PSI | 2200 | 31* |
| R986111159 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986110061 | 74cc | 3600 PSI | 2600 | 52/53 |
| R986110054 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986111250 | 45cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986110806 is 110cc (highest flow per revolution among those listed), while R986111159 is 100cc and R986110061 is 74cc; R986110054 and R986111250 are 45cc options for lower flow needs where a smaller displacement is acceptable.
Pressure Rating
All compared models list 3600 PSI nominal pressure, so pressure-based selection is mainly about confirming your system matches that rating; note that only R986110806 includes a stated 4600 PSI peak pressure in the provided specs.
Speed
Maximum speed varies: R986110806 is 2200, R986111159 is 2300, and the 74cc and 45cc options are 2600, which can matter if your prime mover or duty cycle requires higher allowable RPM.
Quick Selection Guide
Choose: R986110806
Because: When you need 110cc displacement with 3600 PSI nominal pressure and a listed 4600 PSI peak pressure, and your operating speed stays within 2200 max.
Choose: Higher displacement model
Because: When required flow per revolution must be higher than 110cc (confirm against available 31* options not shown here).
Choose: Lower pressure model
Because: When your system operates below 3600 PSI nominal and a different pressure-rated option is acceptable (none of the listed comparison parts are lower than 3600 PSI nominal).
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation. If you’re comparing other piston pumps in the same equipment family, confirm control type and rotation direction as well.
