Sung-il Machinery Co., Ltd. is an experienced manufacturer that started production of precision couplings in 1991 for the first time in Korea. Through consistent effort of research and development, now Sung-il Machinery has the most various coupling product lines in the world.Apart from couplings, Sung-il Machinery has also been doing its best to make the (Factory Automation (FA) industry in Korea more competitive than before, along with its other machine components including support units for ball screws, connecting shafts, A.P locks, etc.
The coupling not only delivers the power and motion of the drive shaft at the same time to the drive shaft, but also absorbs the deterioration factors (vibration, noise, and micro current) of the
misalignment and other equipment.
The safety coupling performs the functions of both power transmission and protective function against overload by combining the features of a coupling and torque limiter.
The A.P. lock connects the shaft and hubs (pulley, gear, etc.) simultaneously and features the holding of various options of various sizes, materials, and surface treatment.
The support unit for the ball screw supports the shaft ends of the ball screws precisely. Sung-il Machinery supports various units for ball screws, depending on sizes, weight, and use.
Product Lines
As the company is preparing to advance into Industry 4.0, equipment technology for the FA industry has been accelerating rapidly and so are FA markets all over the world. In this regard, it now aims to be the world’s best, equipped with significant know-how. The company has accumulated experience as a local major player in Korea over a long period.
Sung-il Machinery currently operates two overseas branches – one in China and the other in Japan. Besides, it has a broad global network, exporting its specialized machine components to more than 30 countries. Moreover, it keeps seeking to expand its sales territory as much as possible. Sung-il Machinery is committed to keeping “Customer Satisfaction” as its first priority core value. It aims to remain a reliable supplier, ensuring that its customers are always satisfied with its services – supreme quality, reasonable pricing and short lead-time.

highly stiffness disk coupling for machine tool. It has zero backlash.
DURIMITEC is aggressively responding to the swiftly changing part industry’s paradigm based on its sales strategies targeting not only for the domestic market but also for potential overseas markets.
CPS Mini Chain is widely used for automation production line and equipment. Cable chain is made of polyamide 6 with glass fiber that helps cable chain perform excellent durability in speedy operating environment. CPS Mini Chain can bear up to 15m/s² of operating conditions. Required operating condition is 6m/sec. There are four series of CPS Mini Chain and CPS030, 033 can be applied to long travel operating environments.
Shift Chain features excellent performance of unsupported length, with easy assembly and disassembly. This is a CPS’ best-selling type of cable chain. When customers especially take account of the factor of ‘unsupported length’, Shift Chain will be a right choice to be selected. There are ‘BR’ (Bending Radius) that determines shift chain’ value of bending radius. Shift Chain is widely used in various environments and it helps customers maintain stock of each part of the shift chain, which means that the shift chain has a simple structure for users to either assemble or disassemble by themselves.

Unity systems are an innovative integral solution by unifying cable chains and bracket supporters.
Korea Coupling manufactures various types of industrial couplings such as steel flex, rigid, flexible, and elastomeric couplings that are mainly used in hydraulic machineries, pumps, compressors, blower fans, conveyors, cranes, and thrusters as well as for general power driven industrial equipment.

Users need to set it up horizontally to control the water level. The connecting wire needs to be long enough for use. Users should have the water tank checked and cleaned periodically. If there is no humidification, users need to turn the power off and check the water level. If water overflows, operators need to turn the water tap off and check the float valve.

Weltem’s portable air conditioner features the so-called “spot cooling” for large areas where cooling of entire areas is impractical like factories, open areas, etc. These conditioners are much more economical to provide cool air to people or material directly, rather than entire cooling. This product also provides a “room-cooling” function for closed areas to control the temperature of the area.
Installing a compact brazed plate heat exchanger leads to an 85~90% reduction in the volume and weight of a shell-and-tube exchanger of the same capacity.
Daegyeong Techwin’s DGTW electronic gas saver reduces cost, enhances safety, and improves convenience of welding work.
Gumsung Poongryuk’s turbo blower AA series has much higher wind-pressure than turbo fans, and is used when air-volume is in the three percent ratio of static pressure.
