Bosch Rexroth R986111411 (Series 52/53) is a precision OEM replacement hydraulic unit for CAT 375-2948, engineered for reliable compatibility and consistent performance in demanding hydraulic circuits.
Technical Specifications
Flow Performance
With a 45 cc displacement, R986111411 delivers predictable volumetric output per revolution to support stable actuator and system response. The displacement profile supports consistent flow characteristics across the operating speed range up to 2600 RPM, enabling repeatable machine behavior under varying load conditions.
Efficiency & Durability
Rated for 3600 PSI nominal pressure with 4600 PSI peak capability, the unit is designed to maintain hydraulic performance under high-load transients without compromising operational stability. Maximum speed of 2600 RPM supports high-duty cycle operation while sustaining consistent output characteristics within the specified pressure envelope.
Installation
Designed as a direct OEM replacement for CAT 375-2948, the R986111411 fits the intended mounting and hydraulic interfaces for straightforward installation. It is intended to install without modifications when replacing the original component in the same configuration.
Features and Benefits
- 45 cc displacement: Provides consistent volume per revolution for predictable system flow response and repeatable control behavior.
- 3600 PSI nominal / 4600 PSI peak pressure rating: Supports high-load operation and manages short-duration pressure spikes without requiring derating under typical transients.
- 2600 RPM maximum speed capability: Enables stable performance at higher operating speeds to maintain required hydraulic output in demanding duty cycles.
Operational Information
Optimized for high-pressure hydraulic operation up to 3600 PSI nominal and 4600 PSI peak, with continuous performance capability up to 2600 RPM. For reliability, operate within the specified pressure and speed limits and maintain system conditions consistent with standard hydraulic component best practices.
Quality Assurance
Manufactured to Bosch Rexroth’s stringent quality standards with rigorous testing throughout the production process.

| Part Number | Displacement | Pressure | Max Speed | Series |
|---|---|---|---|---|
| R986111411 | 45cc | 3600 PSI | 2600 | 52/53 |
| R986110934 | 74cc | 3600 PSI | 2600 | 52/53 |

| R986110680 | 100cc | 3600 PSI | 2300 | 52/53 |
Key Differences
Displacement
R986111411 is 45cc, while the comparison parts range from 71cc to 140cc; choose higher displacement when you need more flow at a given speed, and choose 45cc when your system is sized for lower displacement.
Pressure Rating
All compared models list 3600 PSI nominal pressure; R986111411 also specifies 4600 PSI peak pressure, so confirm your duty cycle and peak events align with the ratings required for your system.
Speed
Max speed is 2600 for R986111411 and for the 71cc and 74cc options, while the 100cc option is 2300 and the 140cc option is 2000; choose a model that meets your required operating speed without exceeding its limit.
Quick Selection Guide
Choose: R986111411
Because: When you need a 45cc displacement unit with 3600 PSI nominal pressure, 4600 PSI peak pressure capability, and up to 2600 max speed within the 52/53 series.
Choose: Higher displacement model
Because: When your required flow exceeds what a 45cc unit can provide, consider 71cc (R986110609), 74cc (R986110934), 100cc (R986110680), or 140cc (R986111453), ensuring the max speed rating also meets your needs.
Choose: Lower pressure model
Because: When system operating pressures are below 3600 PSI nominal, select a component rated appropriately for your system requirements (verify ratings match your application).
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation.
