SUNG-IL MACHINERY CO., LTD is a leading precision couplings manufacturer that provides couplings and factory automation parts for motion control.

Core Products and Technologies
Precision Couplings: Sung-il Machinery offers a broad range of coupling types engineered for efficient power transmission, mechanical protection, and precision alignment. Their product lineup includes:
 Flexible Couplings – Disc types (single and double), slit/beam couplings (SRB series), Oldham couplings, jaw couplings, and bellows—even vibration-damping variants—designed for dynamic motion, minimal backlash, and high torsional rigidity.
 Rigid Couplings – These set-screws, one-piece machined couplings (SRG series) deliver solid torque transmission for systems with precise shaft alignment.
 Specialty Couplings – Zero-backlash disk couplings and others geared toward minimal vibration and high-precision motion control.

Additional Motion Control Parts
Beyond couplings, Sung-il Machinery supplies connecting shafts, essential for smooth motion and accurate torque transfer in robotics, CNC machinery, ...
... and automated systems.

Features and Advantages
 High-Precision and No Backlash: Special designs (e.g., disk-type, SRB series) provide zero backlashes for ultra-accurate motion control.
 Efficient Misalignment Compensation: Products such as Oldham (SOH), jaw, and slit-based couplings absorb angular, parallel, and axial misalignments without compromising performance.
 High Torsional Rigidity and Low Inertia: Materials like aluminum and spring-steel designs ensure responsive, high-speed capability while reducing vibration and energy loss.
 Fast Lead Times and Customization: Sung-il Machinery supports quick production, CAD configuration (2D/3D), and volume discounts—helpful for OEM integration and rapid deployment.

Typical Applications
Sung-il Machinery’s precision coupling solutions are ideal for:
 Servo and Stepper Motors
 Robotics and Automation Systems
 High-Speed, High-Torque Machinery
 Industrial Devices Requiring Zero-Backlash Performance
 Motion Transmission in Demanding Environments (e.g., vacuum, cleanroom)
