Eaton Char-Lynn 4000 Series (4 Series) Medium-Heavy Duty Orbit Motors

Product Overview: The Eaton Char-Lynn 4000 Series (commonly known as the 4 Series) is a premier benchmark for high-performance Low Speed High Torque (LSHT) orbital hydraulic driving. This product category features cornerstone models: 109-1544-006, 109-1689-006, and 109-1264-006. Utilizing advanced Disc Valve technology, the 4000 Series is engineered to maintain peak volumetric efficiency under continuous high-pressure and heavy-load duty cycles. Its patented Geroler® roller set design minimizes internal mechanical friction, ensuring powerful, pulse-free operation even at ultra-low speeds. These motors are the premier choice for combine harvester drives, material handling machinery, construction equipment propel systems, heavy-duty conveyors, and injection molding drives.

Key Technical Advantages:

• Disc Valve Precision: The independent valve plate automatically balances clearances under pressure, providing superior efficiency and significantly longer service life than spool valve motors under high-pressure conditions.

• Geroler® Roller Geometry: Internal roller supports minimize startup friction and ensure powerful, smooth torque delivery across the entire operating range.

• Elite Load Resilience: Robust housing equipped with oversized tapered roller bearings handles massive radial and axial loads directly—ideal for direct-drive wheel or heavy gear-driven setups.

• Technical Decoding:

  • 109-1264-006 / 109-1544-006: Features standard 4-Bolt mounting with high-spec shafts for maximum industrial compatibility.

  • 109-1689-006: Optimized for specific displacement and sealing specifications to meet specialized drive requirements.
