Product Overview
Eaton's Char-Lynn® 109-1212-006 is a low-speed, high-torque orbital hydraulic motor specifically designed for direct replacement and interchangeability. It belongs to the mature 4000 series. With its standardized interfaces and reliable performance, it can seamlessly replace original or other brand hydraulic motors of the same specification in numerous devices, making it an ideal choice for equipment maintenance, upgrades, and standardization of spare parts.
This motor has a displacement of 492.6 ml/rev (approximately 4.9 cu in/rev), adopts a 4-bolt standard flange mounting and a 31.75 mm (1.25 inch) output shaft. Within its compact structure, it provides excellent power density and heavy-load starting capability, and is particularly suitable for industrial and mobile equipment application scenarios that require smooth and powerful direct drive.
Features and Advantages
1. Excellent interchangeability and convenient replacement
◦ Plug-and-play: The standardized 4-bolt flange and 31.75mm output shaft design make it compatible with a large number of motors of the same specification on the market in terms of installation dimensions, enabling quick and unobstructed replacement and greatly reducing equipment downtime.
◦ Solving supply problems: When the original equipment motor is discontinued or has a long procurement cycle, this model provides a reliable and economical alternative.
2. Powerful and stable power output
◦ Optimized displacement design: The displacement of 492.6 mL/rev achieves a good balance between torque and speed, which can not only provide considerable driving force but also maintain a reasonable working speed.
◦ Excellent low-speed performance: The principle of the orbital motor ensures high starting torque and stable operation at low speeds, effectively overcoming the inertia of heavy-load starting.
3. Sturdy and durable industrial quality
◦ Heavy-duty design: High-strength cast iron housing and robust internal bearing design can withstand impacts and continuous loads under harsh working conditions, ensuring long service life and reliability.
4. Low maintenance cost
◦ As a classic series, its repair kits such as seals and bearings are fully available in the market and have strong versatility, reducing the maintenance cost and complexity throughout the life cycle.
Application fields
With its medium displacement, strong torque, and high interchangeability, this motor is widely used in:
- Agricultural machinery: drive for combine harvester headers, seeder metering units, and spreading discs of medium-sized fertilizer applicators.
- Construction machinery: drive for small concrete mixing drums, light winches, and main brushes of industrial sweepers.
- Material handling: direct drive for belt conveyors, screw conveyors, and packaging line turntables.
- Special vehicles: drive for auxiliary mechanisms of sanitation vehicles and driving wheels of aerial work platforms.
