119-1028-003 Char-Lynn 10000 Series Orbital Motor 21in³

Product Overview

The 119-1028-003 (and closely related code 119-1028) is a Danfoss/Eaton Char-Lynn 10000 Series low-speed high-torque Geroler disc-valve orbital hydraulic motor. Featuring a cast-iron housing and highly efficient Geroler design, it is engineered for heavy-duty industrial applications with the industry’s lowest pressure drop and excellent energy efficiency. This unit offers full dimensional and functional interchangeability with genuine Char-Lynn 10000 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. High-efficiency Geroler disc-valve design: Precision Geroler construction delivers the industry’s lowest pressure drop and high volumetric efficiency, significantly reducing energy consumption and improving overall system performance.
2. Cast-iron heavy-duty housing: High-strength cast-iron body combined with robust bearing configuration supports high radial and axial loads for prolonged heavy-duty industrial operation.
3. Full interchangeability: Flange, shaft, ports and overall dimensions match genuine Char-Lynn 10000 Series units exactly, enabling direct replacement without interface modifications and minimizing downtime.
4. High starting torque and low-speed stability: Excellent low-speed characteristics and high starting torque ensure smooth output under heavy-load starting and continuous low-speed conditions.
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 boring and metal-forming equipment
• Port and material-handling machinery
• Sawmill and wood-processing machinery
• Heavy-duty conveyors, winches and continuous-rotation industrial drives

Expert Maintenance Tips

1. Before installation, thoroughly clean the shaft keyway 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 (viscosity 100–200 SUS) and maintain ISO 18/13 cleanliness levels to prevent accelerated wear.
3. Recommended break-in of approximately one hour at 30% of rated pressure before full load; use an external case drain if continuous back pressure exceeds 20 bar.
4. Regularly monitor leakage rate, noise and case 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.
