Product Overview
Eaton Char-Lynn 2K series is a well-known low-speed high-torque hydraulic motor, famous for its disc valve distribution technology and Geroler roller star wheel mechanism. This series achieves excellent power density and extremely high starting and operating efficiency in a compact size. It is particularly good at stably outputting strong torque at extremely low speeds and can directly drive loads, eliminating the need for additional reduction mechanisms. The 604-0475 to 604-0478 you inquired about are four consecutively numbered models in this series, which usually represent specific configurations with differences in displacement, output shaft type, or installation interface under the premise of a consistent core platform.
Features and Advantages
• Classic diamond design: Featuring the iconic two-hole diamond mounting flange, it has a compact structure and flexible installation, achieving maximum torque output in limited spaces.
• True low-speed and high-torque performance: The cycloidal mechanism provides high starting torque and excellent low-speed operation stability, enabling smooth operation at as low as a few revolutions per minute without creeping Phenomenon.
• High power density and economy: It delivers leading torque output with the same overall dimensions, along with mature manufacturing, low maintenance costs, and excellent total cost of ownership.
• Wide applicability: With a robust design and strong anti-pollution capability, it can adapt to relatively harsh working environments.
• Mature maintenance system: Spare parts with part numbers like 604-047X are easily available in the global supply network, making equipment maintenance and lifecycle extension simple and efficient.
Application fields
As one of the most versatile LSHT motors, the 2K series is widely used in:
• Agricultural machinery: Travel drive or rotation of working components in combine harvesters, seeders, fertilizer applicators, and irrigation equipment.
• Construction machinery: Vibration wheel drive of small road rollers, concrete mixing drums, and light winches.
• Material handling: Conveyor belt drive, forklift steering systems, and rotating platforms.
• Industrial equipment: Mixers, tilters, and automatic door drives.
