F12-030-RS-SV-S-000-000 Parker Hydraulic Motor 30cc 500bar 7300rpm

Product Overview

The F12 series is a member of the Parker F11/F12 heavy-duty bent-axis fixed displacement axial piston motor family. The F12 series shares the same 40° bent-axis design philosophy as the F11 series, featuring unique spherical pistons with laminated piston rings, but offers a larger displacement range—from 30 cc/rev to 250 cc/rev. F12 motors are fixed displacement units that can be used as either motors or pumps in both open and closed-loop circuits.

The F12 series delivers maximum intermittent operating pressures up to 480 bar (with certain models up to 500 bar) and speeds up to 7,300 rpm. Core design features include precision gear synchronization and double tapered roller bearings, providing exceptional vibration resistance and high radial load capacity.

Our product provides a fully interchangeable direct replacement for the original Parker F12 series motor, with identical mounting dimensions, port specifications, and shaft configurations. Every unit undergoes 100% simulated duty-cycle testing—performance-validated under rated pressure, peak pressure, and full speed range to ensure volumetric efficiency, mechanical efficiency, torque output, noise levels, and thermal characteristics meet or exceed original OEM specifications.

Key Technical Advantages

1. 40° Bent-Axis Design with Spherical Pistons
The F12 series features Parker’s signature 40° bent-axis design with unique spherical pistons and laminated piston rings. The 40° angle between the drive shaft and cylinder barrel axis delivers a compact, lightweight structure. The spherical piston design significantly reduces internal leakage, improves volumetric efficiency, and provides excellent thermal shock resistance.

2. Gear Synchronization & Double Tapered Bearings
Precision timing gears ensure exact phase synchronization between shaft and cylinder barrel, providing exceptional tolerance to high G-forces and torsional vibrations. Double tapered roller bearings enable the motor to withstand radial loads up to 1,900 kg, while heavy-duty roller bearings support substantial external axial and radial shaft loads.

3. Ultra-High Pressure & High Speed Capability
The F12-030 delivers maximum intermittent pressure of 500 bar and speeds up to 7,300 rpm. The combination of high pressure and high speed provides exceptional power density in a compact package.

4. Low Internal Leakage & High Efficiency
Laminated piston rings minimize internal leakage while delivering high overall efficiency. The 7 or 9-piston design provides high starting torque and smooth motor operation.

5. Modular Mounting & Versatile Configurations
Available with SAE, ISO, CETOP, and cartridge mounting flange options. Shaft ends and port configurations comply with ISO and SAE international standards.
