Bosch Rexroth R986110606 (Series 52/53) is a high-performance OEM replacement for CAT 346-4095, built to deliver reliable, compatible hydraulic power with a 100 cc displacement in demanding systems.
Technical Specifications
Flow Performance
With a 100 cc displacement, the R986110606 delivers consistent, repeatable output per revolution to support stable actuator response and predictable system behavior. At speeds up to 2300 RPM, it maintains strong flow capability for high-demand hydraulic functions while supporting smooth, controlled operation.
Efficiency & Durability
Rated for 3600 PSI nominal pressure with 4600 PSI peak capability, this unit is designed to sustain performance under high loading without sacrificing control. Operation up to 2300 RPM supports productivity while maintaining dependable hydraulic output across typical duty cycles.
Installation
Engineered as a direct OEM replacement for CAT 346-4095, the R986110606 is intended to match OEM mounting and interface requirements for straightforward installation. It is designed to fit without modifications when replacing the original component in the same configuration.
Features and Benefits
- 100 cc displacement: Provides a defined 100 cc per revolution output for predictable flow and consistent machine response.
- 3600 PSI nominal / 4600 PSI peak pressure rating: Supports continuous operation at 3600 PSI with capacity for 4600 PSI peak events to handle high-load transients.
- 2300 RPM maximum speed capability: Enables high-speed operation up to 2300 RPM to maintain hydraulic performance in fast-cycle conditions.
Operational Information
Designed for hydraulic systems requiring up to 3600 PSI nominal pressure and intermittent peaks to 4600 PSI, with operating speeds up to 2300 RPM. Use within the machine’s specified hydraulic fluid and temperature limits to maintain stable performance and reliability.
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) and allowable speed differences. If you’re comparing other hydraulic pumps for similar duty cycles, confirm the circuit type (closed-loop vs. open-circuit) and control requirements first.
?? 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 |
|---|---|---|---|---|
| R986110606 | 100cc | 3600 PSI | 2300 | 52/53 |
| R986110081 | 71cc | 3600 PSI | 2600 | 52/53 |

Key Differences
Displacement
R986110606 is 100cc; alternatives range from 28cc to 110cc, so choose lower displacement (28cc/45cc/71cc) when you need less flow and higher displacement (110cc) when you need more flow than 100cc provides.
Pressure Rating
All listed comparison models are rated at 3600 PSI nominal; R986110606 additionally specifies a 4600 PSI peak rating, so confirm your duty cycle aligns with the pressure ratings required.
Speed
Maximum speed varies across the options (R986110606: 2300; others: 2200–3000), so ensure the selected part’s max speed meets or exceeds your operating speed.
Quick Selection Guide
Choose: R986110606
Because: When you need a 100cc displacement unit with 3600 PSI nominal pressure capability, 4600 PSI peak pressure capability, and a max speed of 2300.
Choose: R986110805
Because: When flow requirements exceed 100cc and you can operate within its 110cc displacement and 2200 max speed limits (3600 PSI nominal).
Choose: R986110045 / R986111374 / R986110081
Because: When you need reduced displacement (28cc/45cc/71cc) and/or higher allowable max speed (2600–3000) while maintaining a 3600 PSI nominal pressure rating. For additional cross-reference options in the same family of piston pumps, compare control type and mounting details.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation.
