CHAR-LYNN

CHAR-LYNN is a brand of hydraulic components, primarily known for its low-speed, high-torque hydraulic motors and cartridge valves. The brand originated in the United States and has been a part of the Eaton (now Danfoss Power Solutions) portfolio for decades, though it continues to be marketed under the CHAR-LYNN name for specific product lines. The core product families include the H Series and S Series rotary actuators (hydraulic motors), solenoid-operated cartridge valves, and associated seal kits. These components are used in applications requiring precise rotary motion control, such as agricultural machinery, construction equipment, industrial material handling, and mobile hydraulics. CHAR-LYNN motors are characterized by their gerotor or geroller design, which provides smooth operation at low speeds with high torque output. The H Series motors typically offer higher pressure ratings (up to 2,050 psi in the listed SKUs) and higher maximum RPM (up to 953 RPM), while the S Series motors are designed for lower speed applications (up to 304 RPM) with pressure ratings up to 1,850 psi. Both series are available with SAE A 2-Bolt or 4-Bolt mounting flanges, with displacements ranging from 3.6 cu in/rev to 73.74 cu cm/rev. The cartridge valves, such as the SV1-16-CM model, are two-way, normally closed solenoid valves with a C-16-2 cavity size and nitrile seals, suitable for hydraulic systems requiring reliable on/off control. Seal kits are available for maintenance and repair, with part numbers like 61334-000 and 9901156-000. 3G Electric stocks over 338 SKUs of CHAR-LYNN products, providing datasheets and logistics support for global procurement. Engineers and maintenance managers can select from a range of displacements, pressure ratings, and mounting configurations to match specific system requirements. The brand's long history in the hydraulics industry means replacement parts and technical documentation are widely available, supporting both new installations and legacy equipment.

Frequently asked questions

Common questions about CHAR-LYNN from 3G Electric.

What is the difference between CHAR-LYNN H Series and S Series hydraulic motors?

The H Series motors are designed for higher speed and pressure applications, with maximum RPM up to 953 RPM and pressure ratings up to 2,050 psi in the listed models. The S Series motors are optimized for lower speed, higher torque applications, with maximum RPM up to 304 RPM and pressure ratings up to 1,850 psi. Both series use a gerotor design but differ in internal geometry and port configurations to suit different duty cycles.

What mounting flange options are available for CHAR-LYNN hydraulic motors?

CHAR-LYNN motors are available with SAE A 2-Bolt, 4-Bolt, and 2-Bolt with 3.25-inch pilot configurations. The SAE A 2-Bolt flange is common for smaller displacements, while the 4-Bolt flange provides additional stability for higher torque applications. The pilot diameter and bolt pattern must match the mating equipment's mounting interface.

What seal materials are used in CHAR-LYNN solenoid cartridge valves?

The CHAR-LYNN solenoid cartridge valves listed use nitrile (Buna-N) seals, which are suitable for petroleum-based hydraulic fluids and a temperature range typically from -30°C to 100°C. For other fluid types or extreme temperatures, alternative seal materials may be available; consult the datasheet for specific compatibility.

How do I identify the correct CHAR-LYNN seal kit for my motor?

CHAR-LYNN seal kits are identified by manufacturer part numbers such as 61334-000 or 9901156-000. These numbers correspond to specific motor models and displacement ranges. To ensure correct fit, match the seal kit part number to the motor's model number and serial number, which are stamped on the motor housing. 3G Electric provides datasheets that list compatible seal kits for each motor SKU.

What is the valve cavity size for CHAR-LYNN SV1-16-CM solenoid valves?

The SV1-16-CM solenoid cartridge valve uses a C-16-2 cavity size. This cavity conforms to industry standard dimensions for two-way cartridge valves, allowing installation in manifold blocks or valve bodies machined to the C-16-2 specification. The valve is two-position, normally closed, and two-way.

Can CHAR-LYNN hydraulic motors be used in continuous-duty applications?

Yes, CHAR-LYNN motors are designed for continuous operation within their rated pressure and speed limits. The H Series motors, with higher RPM capability, are suitable for applications like conveyor drives or fan drives. The S Series motors, with lower RPM and higher torque, are often used in winch drives or auger applications. Always verify the duty cycle against the motor's performance curves provided in the datasheet.
