Eaton Char-Lynn 2000 Series (104/106) High Torque Orbital Hydraulic Motors

Product Overview: The Eaton Char-Lynn 2000 Series (encompassing 104- and 106- series identifiers) is a masterpiece of orbital drive technology, specifically engineered to meet demanding power requirements in medium-to-heavy duty applications. This category highlights essential replacement models: 104-3498-006, 104-1004-006, 104-1031-006, 104-1390-006, and 104-3498-006. Utilizing advanced Disc Valve design and signature Geroler® technology, these motors deliver exceptional mechanical efficiency and smoothness during Low Speed High Torque (LSHT) operations. They are the premier choice for harvester propel drives, large winches, municipal sweepers, material handling conveyors, and injection molding machinery.

Key Technical Advantages:

• Disc Valve Precision: The independent valve plate design compensates for wear automatically and minimizes internal leakage, ensuring superior volumetric efficiency during continuous high-pressure operation.

• Geroler® Roller Technology: Incorporates roller contacts in the star-and-ring set to reduce startup friction, ensuring pulse-free operation and eliminating “cogging” at low RPMs.

• Superior Radial Load Capacity: Equipped with heavy-duty tapered roller bearings, the shaft handles significant side loads directly (e.g., direct sprocket drives), simplifying machine design by eliminating external bearing supports.

• Seamless Drop-in Compatibility: Fully compliant with standard SAE mounting specifications, ensuring a perfect fit as replacements for original Eaton Char-Lynn units to reduce maintenance costs and downtime.

• Technical Spec Decoding:

  • 104- / 106- Series: Identifies 2000 series variants with different flanges (2-Bolt or 4-Bolt SAE) and porting.

  • 3498 / 1004 / 1390: Relates to displacement specifics (100cc to 500cc class) and shaft types (Keyed or Splined).
