Model Number	F12-110-MS-SV-S-000-000-P0, F12-250-QF-SV-F-000-0000-P0

Product Description

Product Overview

The F12 series is a member of the Parker F11/F12 large-frame 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, and offers displacements 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 480–500 bar and continuous operating pressures up to 420 bar, with speeds up to 7,300 rpm. Core design features include precision gear synchronization and heavy-duty roller bearings, providing exceptional vibration resistance and high radial load capacity. The 7 or 9-piston design provides high starting torque and smooth motor operation.

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 delivers a compact, lightweight structure with an excellent power-to-weight ratio. 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 deliver radial load capacity up to 1,900 kg and support substantial external axial and radial shaft loads.

3. High Pressure & High Speed Capability
The F12-110 delivers maximum intermittent pressure of 480 bar and continuous working pressure of 420 bar. Maximum continuous speed reaches 4,400 rpm and intermittent speed reaches 4,800 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. The simple, direct design with few moving parts makes the F12 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

The F12-110-MS-SV-S-000-000-P0 is widely used in drive systems across heavy construction and industrial equipment:

High-Speed Saw Drives: Chain saws, circular saws
Forestry Machinery: Feller bunchers, skidders, forwarders
Construction Equipment: Skid-steer loaders, off-highway trucks
Marine Machinery: Marine deck cranes, constant tension winches, hatch covers
Oil & Gas: Nitrogen pumpers, frac trucks, coil tubing equipment
Industrial Equipment: Fan drives, dust collectors, aircraft test stands
Lifting Equipment: Crane swing and winch drives

Expert Maintenance Tips

Shaft seals and all O-rings must be replaced after every disassembly.
Pre-lubricate all moving parts with clean hydraulic fluid before assembly.
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.
Recommended maximum system operating temperature should not exceed 80°C; drain oil temperature should not exceed 115°C.
Monitor case drain flow regularly—an abnormal increase indicates potential piston ring or cylinder barrel wear.
Ensure hydraulic system filtration meets β₁₀ ≥ 75 (ISO 4406 cleanliness code不低于 18/16/13) to maximize motor service life.
Weight is approx. 33–36 kg—use proper handling procedures during installation and removal.
The F12-110 features SAE 6000 psi flange ports and SAE 4-bolt flange—ensure port sealing surfaces are clean and undamaged during installation.
