The Eaton Char-Lynn 4K (i.e., 4000) series, model 109-1192-006, is a Geroler™ hydraulic motor specifically designed for heavy-duty, high-torque industrial applications. Its core feature lies in the adoption of a robust splined output shaft and a reinforced square mounting flange. This combination provides excellent torque transmission capability and structural rigidity, making it particularly suitable for harsh working conditions that require withstanding high radial loads and severe impacts. As a model of low-speed high-torque (LSHT) motors, it can smoothly deliver powerful output at low speeds, making it an ideal choice to replace complex gearbox drive systems.

1. High-strength spline shaft:
◦ Efficient torque transmission: Compared with a flat key shaft, the spline shaft has a larger contact area, enabling it to transmit greater torque with a more stable connection.
◦ Excellent alignment and fatigue resistance: Spline fitting can better adapt to dynamic loads, reduce stress concentration, and extend the service life of the shaft and connected equipment.
◦ Common standards: Usually comply with SAE or ISO spline standards, facilitating direct matching with gears, sprockets, or couplings available on the market.
2. Heavy-duty square flange:
◦ Excellent load-bearing and torsional rigidity: The square flange structure provides a larger installation base surface and more optimized bolt distribution, which can effectively resist complex moments and radial forces, and its installation stability is far superior to that of circular flanges.
◦ Easy installation and positioning: The square design facilitates quick positioning and leveling on the equipment frame.
◦ Industry universality: Commonly used in metallurgy, mining, heavy-duty conveying and other equipment, with a high degree of interface standardization.
3. Gerole star wheel roller technology:
◦ High efficiency and long service life: The core rolling contact (roller) design results in low friction loss, high mechanical efficiency (up to 95% or more), and large starting torque.
◦ Excellent low-speed stability: It can run stably even at extremely low speeds (such as 1 rpm) without "creeping" phenomenon.
◦ Sturdy and durable: The design can withstand high impact pressure and working load, with high reliability.

Thanks to its heavy-duty design, the model 109-1192-006 is highly suitable for the following fields:

• Heavy-duty material conveying: driving large belt conveyors, plate feeders, and the slewing mechanisms of stackers and reclaimers.
• Metallurgical and mining equipment: used in ladle turrets, feeding devices of ore crushers, and wheel hub drives of mining vehicles.
• Engineering and construction machinery: driving the main mixing machines of concrete mixing plants, mixing rotors of stabilized soil mixers, and slewing platforms of large drilling rigs.
• Marine and port machinery: slewing drives for deck machinery such as winches and cargo cranes.
• Energy equipment: yaw drive test devices for wind turbines and direct drives for special pumps.
