Bosch Rexroth R986110102 (Series 52/53) is a direct OEM replacement for CAT 153-7021, delivering compatible fit and consistent hydraulic output for reliable machine performance.
Technical Specifications
Flow Performance
With a 100 cc displacement, the R986110102 provides predictable volume delivery per revolution to support stable actuator and drive performance. Rated for speeds up to 2300, it maintains consistent flow characteristics across the operating range for responsive hydraulic control.
Efficiency & Durability
Designed to operate at a nominal pressure of 3600 PSI with peak capability to 4600 PSI, this unit supports high-load hydraulic demands without sacrificing performance consistency. The Series 52/53 design is intended to sustain output at elevated pressures and up to 2300 max speed, helping reduce performance drift under continuous duty.
Installation
Engineered as an OEM replacement for CAT 153-7021, the R986110102 is intended for direct fit and standard mounting compatibility. Installation is straightforward as a drop-in replacement with no modifications required.
Features and Benefits
- 100 cc displacement: Delivers consistent volume per revolution to support predictable machine response and repeatable hydraulic performance.
- 3600 PSI nominal / 4600 PSI peak pressure capability: Supports demanding load conditions while maintaining controlled hydraulic output during pressure transients.
- 2300 maximum speed rating: Enables reliable operation at higher rotational speeds to sustain required flow delivery within the specified operating envelope.
Operational Information
Operate within the specified pressure limits (3600 PSI nominal, 4600 PSI peak) and up to 2300 max speed to maintain stable performance. The 75 weight and Series 52/53 configuration support dependable operation in typical hydraulic system conditions when installed and operated within the machine’s standard parameters.
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 3600 PSI nominal pressure class, so selection is primarily driven by displacement (flow need) and the maximum speed capability.
?? 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 |
|---|---|---|---|---|
| R986110102 | 100cc | 3600 PSI | 2300 | 52/53 |

Key Differences
Displacement
R986110102 is the highest displacement option listed at 100cc, while the comparison parts range from 45cc to 71cc; higher displacement supports higher flow per revolution, while lower displacement is typically chosen when less flow is required.
Pressure Rating
All listed comparison parts are rated at 3600 PSI (nominal), matching the current product’s nominal pressure; only R986110102 lists a peak pressure spec (4600 PSI), so confirm peak pressure requirements when comparing.
Speed
R986110102 is listed at 2300 max speed, while the comparison parts are listed at 2600; if your duty cycle requires higher maximum speed, the 2600-rated options may be a closer fit, provided displacement meets your flow needs.
Quick Selection Guide
Choose: R986110102
Because: When you need 100cc displacement with 3600 PSI nominal pressure, 4600 PSI peak capability, and a 2300 max speed limit.
Choose: Higher displacement model
Because: When required displacement (cc) and resulting flow per revolution must be higher than 100cc to meet system flow demand.
Choose: Lower pressure model
Because: When the system operates at lower pressures than 3600 PSI nominal and a lower-rated component is acceptable.
Compatibility: Verify mounting pattern, shaft configuration, and port sizes match your existing installation. If you’re comparing options across our hydraulic pumps lineup, confirm the interface details before selecting an equivalent unit.
