Bosch Rexroth R986110062 (Series 52/53) is an OEM replacement for CAT 100-3259 engineered to deliver compatible fit and consistent hydraulic performance under demanding pressure and speed conditions.
Technical Specifications
Flow Performance
With a 71 cc displacement, R986110062 provides predictable volumetric output per revolution for stable actuator response and controllable machine motion. Designed for operation up to 2600 max speed, it supports strong flow capability across the operating range while maintaining consistent performance characteristics.
Efficiency & Durability
Rated for 3600 PSI nominal pressure and 4600 PSI peak pressure, this unit is built to sustain performance under high-load hydraulic cycles. Its 2600 max speed capability supports rapid system response while maintaining reliable operation within the stated pressure limits.
Installation
Configured as a direct OEM replacement for CAT 100-3259 for straightforward installation and OEM-equivalent interface compatibility. Intended to fit without modifications when replacing the original component.
Features and Benefits
- 71 cc displacement: Delivers consistent displacement per revolution to support stable flow output and repeatable machine motion.
- 3600 PSI nominal / 4600 PSI peak pressure rating: Handles high working pressures with defined peak capacity for transient load events.
- 2600 max speed capability: Supports higher rotational speeds for responsive hydraulic performance within the specified operating limits.
Operational Information
Operate within the stated 3600 PSI nominal and 4600 PSI peak pressure limits and up to 2600 max speed to maintain consistent performance. The 48.5 weight reflects a robust build suited for continuous-duty hydraulic service.
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 are best compared by matching displacement (flow per revolution), then confirming the same 3600 PSI nominal pressure rating and allowable speed for your duty cycle. If you’re still narrowing down options, review our piston pumps selection for comparable Rexroth-style configurations.
?? 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 |
|---|---|---|---|---|
| R986110062 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986111258 | 140cc | 3600 PSI | 2000 | 31* |

| R986110106 | 71cc | 3600 PSI | 2600 | 52/53 |
| R986110581 | 74cc | 3600 PSI | 2600 | 52/53 |
Key Differences
Displacement
R986110062 is 71cc; alternatives range from 60cc (R986110069) to 74cc (R986110581) and up to 140cc (R986111258). Choose higher displacement when you need more flow at the same speed, or lower displacement when you want less flow per revolution.
Pressure Rating
All compared models list 3600 PSI nominal pressure, aligning with R986110062; ensure your system also accounts for the current product’s 4600 PSI peak requirement where applicable.
Speed
R986110062, R986110069, R986110106, and R986110581 are listed at 2600 max speed, while R986111258 is listed at 2000; select a model that meets or exceeds your required operating speed.
Quick Selection Guide
Choose: R986110062
Because: When you need a 71cc unit with 3600 PSI nominal (4600 PSI peak) capability and up to 2600 max speed in a Series 52/53 replacement.
Choose: Higher displacement model
Because: Choose R986111258 (140cc) when your flow requirements are higher than a 71cc unit can provide, while maintaining a 3600 PSI nominal rating (note its 2000 max speed).
Choose: Lower pressure model
Because: Not applicable within this comparison set, as all listed alternatives are rated 3600 PSI nominal; select based on displacement and speed instead.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation. For broader options across similar hydraulic pumps, compare mounting and control styles before finalizing a replacement.
