Eaton Char-Lynn 4000 Series Heavy-Duty Orbital Hydraulic Motors

Product Overview: The Eaton Char-Lynn 4000 Series (109- Series sequence) is synonymous with heavy-duty power in the orbital motor industry. This category features critical replacement models: 109-1116-006, 109-1105-006, 109-1544-006, 109-1052-006, 109-1118-006, and 109-1104-006. Engineered with advanced Disc Valve technology and Geroler® sealing, the 4000 series motors are built to withstand high pressure, massive torque, and extreme radial loads. They are the premier power source for large agricultural propel drives, marine deck cranes, heavy material handling, drilling rigs, and industrial shredders.

Key Technical Advantages:

• Disc Valve Precision: The independent valve plate design compensates for wear and minimizes internal leakage, ensuring smooth, highly efficient power delivery even under ultra-high pressures and low RPMs.

• Geroler® Roller Geometry: Roller-contact elements significantly reduce startup friction, eliminating pulse or “cogging” during Low Speed High Torque (LSHT) operation.

• Superior Radial Load Capacity: Equipped with heavy-duty tapered roller bearings, the shaft handles significant side loads directly—simplifying machine design by removing the need for external bearing supports.

• High-Pressure Seal Integrity: Proprietary shaft seals handle high back pressures, ensuring leak-free performance during intense cycles and frequent reversing.

• Technical Spec Decoding:

  • 109- Series: Identifies the classic Eaton 4000 Series disc valve architecture.

  • 1116 / 1105 / 1544: Relates to displacement specifics (160cc to 500cc class), mounting flanges (e.g., 4-Bolt SAE B), and shaft types (Keyed or Splined).
