F11-010-MB-CV-K-209-0000-0X Parker Hydraulic Motor 9.8cc 420bar

Product Overview

The F11 series is a member of the Parker F11/F12 small-frame bent-axis fixed displacement axial piston motor family. The F11 series shares the 40° bent-axis design philosophy with unique spherical pistons and laminated piston rings, offering displacements from 4.9 cc/rev to 19.0 cc/rev. F11 motors are fixed displacement units that can be used as either motors or pumps in both open and closed-loop circuits.

The F11-010 is the 9.8 cm³/rev displacement model in the F11 series—one of the most widely used specifications in the family. The F11 series delivers maximum intermittent operating pressures up to 420 bar and continuous operating pressures up to 350 bar, with speeds up to 14,000 rpm. Core design features include precision gear synchronization and heavy-duty roller bearings, providing exceptional vibration resistance and high radial load capacity.

Our product provides a fully interchangeable direct replacement for the original Parker F11 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 F11 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 & Heavy-Duty Roller Bearings
Precision timing gears ensure exact phase synchronization between shaft and cylinder barrel, providing exceptional tolerance to high G-forces and torsional vibrations. Heavy-duty roller bearings support substantial external axial and radial shaft loads.

3. Ultra-High Speed Capability
The F11-010 delivers speeds up to 10,200 rpm. Thanks to lightweight pistons and compact rotating components, the F11 series tolerates extremely high speeds up to 14,000 rpm.

4. Low Internal Leakage & High Efficiency
Laminated piston rings minimize internal leakage while delivering high overall efficiency. The simple, direct design with few moving parts makes the F11 series exceptionally reliable.

5. Compact Design & Wide Temperature Range
Compact housing with excellent power-to-weight ratio. Operating temperature range from -40°C to +115°C enables reliable performance in both extreme cold and high-temperature environments.

Application Areas

• High-Speed Saw Drives: Chain saws, circular saws

• Agricultural Machinery: Combines, windrowers, balers

• Construction Equipment: Mini-excavators, skid-steer loaders

• Forestry Machinery: Logging equipment

• Industrial Equipment: Industrial hydraulic systems, winch drives

• Closed & Open Circuits: Hydrostatic transmission systems

Expert Maintenance Tips

1. Shaft seals and all O-rings must be replaced after every disassembly.

2. Pre-lubricate all moving parts with clean hydraulic fluid before assembly.

3. Purge all air from the motor housing before initial start-up—ensure the case drain line returns directly to the reservoir with the outlet below the oil level to prevent air entrapment and bearing starvation.

4. Monitor case drain flow regularly—an abnormal increase indicates potential piston ring or cylinder barrel wear.

5. Recommended maximum system operating temperature should not exceed 80°C; drain oil temperature should not exceed 115°C.

6. Ensure hydraulic system filtration meets β₁₀ ≥ 75 (ISO 4406 cleanliness code不低于 18/16/13) to maximize motor service life.

7. Weight is approx. 7.7 kg—use proper handling procedures during installation and removal.
