[INQ. NO. 2506M04] NARA Drive Co., Ltd. is a world-class company in the power-transmission sector, and is recognized as an honest company with the best products and top-quality service as its core values.
NARA Drive is a manufacturer and distributor of gears and power transmissions such as couplings, turning gears, and fluid transmissions. It has acquired a lot of export experience in the Japanese market.

Gear Couplings
NARA Drive’s gear couplings are compact and lightweight, and there is almost no noise or vibration even at high speeds.
Even if there is some shaft misalignment in the coupling during installation and use, it is absorbed by self-adjustment, so it protects the machine part and transmits strong power, and internal lubrication increases the wear resistance of the gear.
They can be used under heavy loads and at high speeds, and can also be used when rotating while sliding. Furthermore, they are easy to apply when the distance between the axes is long and must be connected by an intermediate shaft. Large and special types can also be manufactured.

Jaw Couplings
NARA Drive’s jaw couplings have excellent shock absorption and vibration absorption capacity due to power transmission by polyurethane elements. They offer excellent wear resistance, ozone resistance, oil resistance, and chemical resistance. They have a simple structure and are small compared to their transmission capacity. Moreover, they do not require lubrication.
“We are confident in our fast delivery, special specifications, price, etc. Please feel free to contact us. We are aiming to enter the Japanese market for planetary gear reducers and couplings for automation,” explained the CEO of the company.

https://korean-machinery.com///inquiry[INQ. NO. 1803M06] Woo Jin Industry has since its establishment in 1991 been focused on producing various rollers for industry, rollers for financing machinery, office equipment, and flexible couplings by using polyurethane materials.
Especially, the company’s recent flagship couplings MAX DYNAMIC® and MAX FIELD®, respectively made of made of polyurethane, have been being exported to over 28 countries and they have been well received in overseas markets by acquiring ATEX (II2GD c T5) CE certification.
Woo Jin Industry’s Max Dynamic ® is the company’s current flagship product and is designed for facility protection for prevention of twist, impact, and abrasion. This coupling allows very simple replacement and maintenance without any oil or grease. Very simple replacement is possible without the separation of motor or connector on the related line due to its simple structure. It is possible for the dissimilar connection and assembly with the same hub. It is polyurethane-based product for good water and chemical resistance. It boasts the highest-level flexible elasticity on run. It creates less noise than existing ones.
This coupling is applied at such various places as agitators, blowers, compressor, conveyors, cranes, hoists, elevators, fans, generators, pumps, food industry, pulp & paper mills, rubber industry, steel industry, textile mills, aggregate processing cement, etc.
Woo Jin Industry is committed to becoming a company making constant efforts toward providing products of the best quality and to creating a clean global environment as well. Woo Jin Industry aims at establishing global networks in an attempt to fully meet the demands of promising global markets. Until now, Woo Jin Industry placed its emphasis on elevating its local presence through satisfying partner companies’ demands based on its own technology and related services.

Couplings, Clamps

January 17, 2018 by Leave a Comment

https://korean-machinery.com///inquiry[INQ. NO. 1801M08] Founded in 1995, Jung Woo Coupling, a small company, manufactures couplings and clamps to connect pipes. However, the company has been recognized as a small but strong company in exporting to 35 countries including Japan, the USA, the UK, France, Norway and Australia.
Couplings connect two pipes and are mainly used for the installation of pipes. Clamps are used to fix or overlay pipes on other pipes for maintenance purposes. Couplings and clamps are recognized as products that can replace existing cumbersome and difficult piping connections such as welding. If a user only locks bolts on couplings and clamps, the user can easily connect pipes, thereby saving the user work time and cost.
Couplings and clamps can be used in a variety of industries including shipbuilding, power generation, chemical, petroleum, housing, and construction. Couplings and clamps are already widely used in Europe such as the UK and Germany, but not in Korea.
For this reason, Jung Woo Coupling is known as the best manufacturer in the field of couplings and clamps in Korea. “With only one or two companies producing pipe couplings and clamps in Korea, our company feels a sense of responsibility as a leading company in Korea,” remarked Yoo In-tae, CEO of Jung Woo Coupling. “In particular, we are proud of the fact that we are recognized around the world as we have invested in research and development over the past 16 years.”

Jung Woo Coupling has concentrated its research efforts on improving quality and technology since its establishment. The company registered four utility models by applying their own technology to foreign products. As an example, Jung Woo Coupling improved the compression of saw teeth of pipes’ connection parts of couplings to prevent leaks and improve connection strength.
In addition, the company made products that can be used only for straight pipes available for “ㄱ-shaped” pipes, and enhanced product performance so that pipes made of different materials can be connected. That is to say, they made installation work easier by developing assembly-type couplings that connect large sewer pipes that pass through cities and small sewer pipes for homes.
Compared to this technology, Jung Woo Coupling products are about 30% cheaper than those of overseas major manufacturers. Jung Woo Coupling secured cost competitiveness through quality management by reducing cost through quality certification and reducing expenses incurred in the production process.

[INQ. NO. 1510M16] Youngnam Metal has 28 years of experience in manufacturing of pipe joint products such as multi-flex type couplings, grip ring type couplings, repair clamps and other pipe connectors. Its technical capacity in this field has been highly appraised by many clients and concerned parties to save costs.

https://korean-machinery.com///inquiry Nowadays, pipe joints are steadily being replaced by increasing use of flanged pipe joints with various heavy industrial applications to shipbuilding owing to their flexibility and economy. These coupling joints eliminate welding costs and prevent any linear expansion and defl exion of the piping by welding repairs. The company promises it will try maximum in your company by lowest price, the superlative quality and timely delivery of goods.

Couplings Youngnam couplings are the easiest way to join and repair pipes of all materials. They require no special tools or pipe-end preparation. They handle pipe-misalignment, vibration, and are used in shipbuilding, wastewater treatment, general industry, and construction. They come fully assembled and ready to install. A torque wrench is the only tool required to do the job. Light weight and with a low profile. The couplings are easy to handle and can be installed in the tightest of spaces. The unique lip seal design seals on even rough pipe surfaces. The couplings are used to join and repair virtually any plain end pipe or tube including steel, stainless steel, ductile iron, FRP, PVC, CPVC, C900, concrete pipe, copper and CuNi piping.
