110A-164 Parker 110A Series Orbital Motor 269cc High Torque

Product Overview

The 110A-164 / 111A-106 / 111A-129 / 115A-129 (complete model examples: 110A-164-FS-0, 111A-106-AS-0, 111A-129-AS-0, 115A-129-AS-0) is a Parker Nichols 110A/111A/115A series low-speed high-torque orbital hydraulic motor. Featuring a one-piece solid shaft and pressure-loaded power element design, it delivers a compact package with high volumetric efficiency optimized for industrial and mobile applications. This unit offers full dimensional and functional interchangeability with genuine Parker 110A 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 low-speed high-torque output and continuous load.

Key Technical Advantages

1. One-piece solid shaft design: Full stationary spline contact between shaft and rotor minimizes spline stresses, significantly extending service life and supporting rapid reversals.
2. Pressure-loaded power element: Power element is pressure-loaded against internal leakage for high volumetric efficiency; wear-compensated design maintains efficiency over time.
3. Full interchangeability: Flange, shaft, ports and overall dimensions match genuine Parker 110A series units exactly, enabling direct replacement without interface modifications and minimizing downtime.
4. Compact high power density: The most compact design in its class, supporting high side loads (up to approx. 1450 lb) for space-constrained heavy-duty 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

• Industrial conveyors, positioners and machine tools
• Agricultural machinery and feed equipment
• Construction equipment auxiliary drives and winches
• Compact low-speed high-torque applications requiring high starting torque

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; use anti-wear hydraulic oil and maintain cleanliness levels to prevent accelerated wear.
3. Fully warm up the system and verify oil level and circuit pressure before starting; avoid dry starts and observe side-load limits.
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.
