Product Description

Product Overview

The F12-110 / F12-250 (complete model examples: F12-110-MS-SV-T-000-0000-PT, F12-250-QF-SV-S-000-0000-PO) is a Parker F12 series fixed-displacement bent-axis piston hydraulic motor. Featuring patented spherical piston and gear synchronization design, it delivers exceptional overall efficiency, high speed capability and robust pressure performance for open- or closed-circuit applications. This unit offers full dimensional and functional interchangeability with genuine Parker F12 series motors, matching flange, shaft, ports and overall envelope for direct drop-in replacement. Every unit undergoes 100% simulated operating-condition testing to guarantee consistent performance under high speed, high pressure and continuous load.

Key Technical Advantages

  1. Patented spherical piston design: Spherical pistons combined with precision cylinder barrel deliver exceptional overall efficiency and thermal shock resistance, enabling unusually high shaft speeds.
  2. Gear synchronization and double tapered bearings: Reliable timing gear and heavy-duty bearing arrangement ensure stability and long service life under high pressure and high speed.
  3. Full interchangeability: Flange, shaft, ports and overall dimensions match genuine Parker F12 series units exactly, enabling direct replacement without interface modifications and minimizing downtime.
  4. High power density and compact design: 40° bent-axis geometry provides outstanding power-to-weight ratio ideal for space-constrained high-speed applications.
  5. 100% simulated-condition testing: Every unit is fully tested for pressure, speed, leakage and noise characteristics prior to shipment, ensuring consistent out-of-box performance.

Application Areas

  • Construction and forestry equipment high-speed drives
  • Marine, offshore and oil & gas applications
  • Agricultural machinery and mining equipment
  • Municipal vehicles and open/closed-circuit systems requiring high speed and efficiency

Expert Maintenance Tips

  1. Before installation, thoroughly clean the shaft and flange face; use correct seals and bolt torque values to avoid misalignment or sealing-surface damage.
  2. The system must include adequate filtration and overpressure protection; maintain recommended viscosity range and cleanliness levels to prevent accelerated wear.
  3. Fully warm up the system and verify case drain and circuit pressure before starting; avoid dry starts and observe case-pressure limits that vary with speed.
  4. Regularly monitor leakage rate, noise and temperature; when changing fluid and filters, follow recommended grades.
  5. Protect shaft and ports against corrosion during storage; avoid prolonged exposure to moisture or corrosive environments.
