NARA AUTOSYS – Power transmission technology for demanding systems

From precision motion in automation to high-power transmission in industry

WHEN POWER TRANSMISSION PERFORMANCE BECOMES AN OPERATIONAL ADVANTAGE

Founded in South Korea in 1977, NARA AUTOSYS develops power transmission solutions for a wide range of applications—from servo mechanisms requiring high precision to heavy-duty industrial systems. Rather than offering a single standalone product, NARA’s portfolio forms an integrated solution range comprising precision planetary gearboxes, multiple types of industrial couplings, and variable speed fluid couplings.

A key strength of NARA is its ability to address two seemingly different requirements: precise motion control in automation and stable power transmission in industrial production lines. This provides a solid foundation for selecting configurations according to the load, speed, installation space, and operating characteristics of each system.

PRECISION PLANETARY GEARBOX – COMPACT, PRECISE, READY FOR AUTOMATION

NARA’s planetary gearbox range is developed for servo systems and automation equipment requiring precise motion control. The NP, NPR, NF, NFR, NX and NZ series offer various configurations, including inline, right-angle, flange, flange-angle, fixed tapped and compact designs, giving engineers greater flexibility when arranging equipment.

• Helical gear design – engineered for smooth operation and low noise.
• Multiple mounting configurations – suitable for robots, machine tools, semiconductor equipment, laser systems and automated production lines.
• Space-efficient design – compact and right-angle models are well suited to systems with mechanical layout constraints.

COUPLING – THE RIGHT CONNECTION FOR MORE RELIABLE SYSTEM OPERATION

NARA offers a diverse coupling portfolio to meet different torque transmission and shaft connection requirements. Depending on the application, businesses can select Gear Coupling, Disc Coupling, Jaw Coupling, Chain Coupling, Flexible Flanged Coupling, Drum Coupling or Fluid Coupling. This diversity means coupling selection goes beyond simply “connecting two shafts” and focuses on matching the load, shaft misalignment, vibration and equipment characteristics.

For high-power systems, Variable Speed Fluid Coupling adds speed-control capability based on hydrodynamic principles. NARA’s catalogue specifies a developed range of up to approximately 14,000 kW and 15,000 rpm, depending on configuration. The solution is suitable for applications such as pumps, fans, conveyors, crushers and equipment requiring smoother starting or speed variation.

ONE TECHNOLOGY PLATFORM – MULTIPLE APPLICATION ENVIRONMENTS

NARA products can be used at multiple points throughout a plant: precision motion mechanisms in robots and machine tools; couplings in pumps, compressors and drive systems; and fluid couplings in conveyors, crushers and heavy-duty equipment. The catalogue also presents applications in power plants, steel, petrochemicals, lifting equipment and marine systems.

NARA AUTOSYS – FROM POWER TRANSMISSION COMPONENTS TO SYSTEM-SUITABLE SOLUTIONS

With a development history dating back to 1977 and a product portfolio spanning precision planetary reducers, couplings and variable speed fluid couplings, NARA AUTOSYS is a solution provider worth considering for businesses seeking power transmission solutions that combine precision, stability and adaptability across a wide range of operating conditions.
