Eaton's 4000 series is a hydraulic motor designed specifically for medium to high torque, medium to high pressure hydrostatic transmission systems. The model 109-1119-006 represents a specific configuration under this series, featuring a 4-bolt SAE-B square mounting flange and a 1-1/4 inch 14-tooth spline output shaft. This design is intended to provide stable and reliable installation as well as efficient power transmission, and is widely used in agricultural, construction, and industrial applications where equipment requires strong and smooth driving force.

1. Stable Installation and Power Interface
◦ 4-bolt SAE-B square flange: Compared to 2-bolt flanges, it provides stronger rigid connection and torsional resistance, suitable for harsh working conditions with high torque and impact loads.
◦ 1-1/4″ 14-tooth splined shaft: A standardized heavy-duty spline interface that can transmit extremely large torque, with good connection rigidity and excellent centering performance, making it an ideal choice for achieving direct and reliable power transmission.
2. Excellent medium and high pressure performance
◦ High power density: Within a compact size, it outputs huge torque with a continuous working pressure of up to 4000 psi, meeting the power requirements of heavy-duty equipment.
◦ Excellent low-speed stability: It can operate stably even at extremely low speeds, providing uniform torque, which is very suitable for driving walking machinery or equipment that requires precise speed control.
3. Reliability and durability
◦ Heavy-duty design: The overall structure is robust, key friction pairs are made of wear-resistant materials, and the bearings have a long service life. It is specially designed to withstand vibrations and impacts in field or industrial environments.
◦ Wide application compatibility: Its performance parameters and interface standards are highly matched with the hydraulic systems of mainstream medium and large agricultural machinery and engineering machinery.

Thanks to its characteristics of high pressure and high torque, this model of motor is an ideal choice for the drive systems of the following equipment:
• Agricultural machinery: travel drive of combine harvesters, hydrostatic drive axle (HST) of large tractors, chassis drive of sugarcane harvesters.
• Engineering and construction equipment: vibration wheel drive of small and medium-sized road rollers, crawler travel drive of pavers, slewing drive of rotary drilling rigs.
• Industrial equipment: travel drive of rubber-tyred gantry cranes (RTG) in ports, drive of driving wheels of large conveyors, ship winches.
• Forestry machinery: drum or travel drive of skidders.
