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 choice for high-performance medium-to-heavy duty hydraulic driving. This category focuses on the flagship models: 109-1246-006, 109-1104-006, and 109-1173-006. Utilizing precision Disc Valve technology, the 4000 Series is engineered to maintain exceptional volumetric efficiency under continuous high-pressure conditions. Featuring patented Geroler® roller sets, internal mechanical friction is significantly reduced, ensuring smooth and pulse-free power delivery in Low Speed High Torque (LSHT) applications. These motors are the primary choice for harvester drives, injection molding machinery, material handling equipment, heavy-duty conveyors, and drilling machinery.

Key Technical Advantages:

• Disc Valve Precision: The independent valve plate automatically balances clearances under pressure, providing superior efficiency and significantly longer service life compared to spool valve motors under heavy duty cycles.

• Geroler® Roller Geometry: Internal roller supports minimize startup friction and ensure powerful operation even at minimal speeds.

• Elite Radial Load Resilience: Equipped with oversized tapered roller bearings, the housing handles massive radial and axial loads directly—perfect for direct-drive wheel or gear-driven setups.

• Technical Decoding:

  • 109-1104-006 / 109-1246-006: Features standard 4-Bolt mounting and heavy-duty shaft options for maximum stability.

  • 109-1173-006: Optimized for specialized high-pressure scenarios with reinforced sealing and enhanced drive link durability.
