Since its establishment in 1993, Sejin-iGB has progressed and expanded its business to keep pace with engineering innovations in advanced transmission technology. Through the manufacture and sales of high-precision linear and rotary transmissions, Sejin-iGB is committ ed to providing advanced engineering solutions in industrial automation.
With 20 years of high-precision transmission research, Sejin-iGB contributes to high-quality and optimized solutions for customers who need more sophisticated and higher accuracy in the industry.
Sejin iGB always endeavors to provide high-precision reducers with the best technology, products and service to its customers. A reducer is a kind of power transmission system and is a core component used in industrial automation machinery. This equipment generates large torque, instead of reducing the speed. Sejin iGB has been producing high-precision reducers for more than 20 years, and it has focused on technologies that everybody strives for, but nobody has achieved yet.
Producing the Best High-Precision Reducers in Terms of Performance
High-precision reducers contain fused technologies, such as mechanical, control, materials, electrical and electronic engineering. Sejin iGB consistently off ers creative and innovative products of its own brand to customers, and all products are based on systematic technology roadmap. The original and new Sejin iGB reducers are extending their usability in the domestic market that used to import mainly foreign products. However, Sejin iGB is now improving its competence of the company by maintaining the highest standard in terms of performance.
By developing high-precision reducers for industrial robots, the defense sector, rack and pinion fusion modules, semiconductors and medical equipment, sales in the overseas market are likely to increase. High-precision position control modules are fused with deceleration, high-speed gear ratio, compact and lightweight and lownoise equipment. Thus, the reducers for robots and automation equipment will be greatly improved in terms of performance and reliability.
As for high-precision reducers that represent product lines of the company, there are CRP, XQ Power, RPM and SS series. The CRP (Clean Rack Pinion) series features clean installation, various selections, integer movement, multiple tooth contact, generated tooth profi le, high acceleration and high effi ciency without noise. They are highly dynamic and simple to use. The SS (Space Saver) series feature space saving right angle, universal installation, full protection and high tilting rigidity. They are also quiet and highly dynamic.

Saw blades are the most traditional and essential tools for cutt ing materials to required dimensions. In particular, Tungsten Carbide-Tipped (TCT) circular saw blades are capable of operating at much higher temperatures (Max. 400 °C) and cutt ing at a much higher surface speed (max. 350 M/min).
a group of newly developed products to meet global customers’ needs. Their remarkable chip removal eff ects enable clean cuts, fast cuts and longer blade life. AlTiN coating increases wear resistance.

A condenser is required to cool down the hot refrigerant coming from a compressor, so it is located at the front of a car where it can be exposed to the maximum amount of air. As the hot refrigerant fl ows into the condenser, it dissipates heat by fl owing through a system of ultra-thin tubes that are held together by fi ns.
engine via a V-belt or ribbed V-belt.As low-pressure liquid refrigerant from the evaporator fl ows into the compressor, the liquid is compressed into high pressure gas and sent to the condenser. These units compress liquid refrigerant into gas while keeping the refrigerant fl owing through the airconditioning system. Compressors are also fi lled with special lubricating oil, and some of this oil circulates with the refrigerant through the air-conditioning system, keeping all of the parts lubricated.
A radiator is located at the front of a car’s engine, just behind the condenser, and is the most important component of the cooling module because it keeps the engine from overheating.
tanks, and all the necessary connections and att achments. The radiator core is made up of a network of fi ns and tubes that run either horizontally or vertically, depending on the application.

The story of Alton Sports is a story of a pioneer, braving the turbulence of the market and forging a new path to become the one and only self-producing bicycle brand in Korea.
In Korea, KITURAMI Co.has been synonymous with home boilers for the past 54 years. By taking over domestically leading makers of air conditioners, cooling towers and refrigerating machines in the mid-2000s, the company has emerged as a substantial powerhouse of the domestic HVAC (Heating, Ventilation, Air conditioning) industry.
spectrum of HAVC products, including gas boilers, oil boilers, medium-size boilers, solid fuel boilers, water heaters, fan coil units, ventilation systems, burners and pumps. Having actively explored foreign markets, it has obtained a variety of foreign certifi cations such as ETL (North America), TRCU(Russia, Kazakhstan, Belarus), CCC (China), TSE (Turkey), CSA (Canada), UL (the US), and CE (the EU).
Among the company’s popular export items are premium-type instantaneous gas water heaters, hot water storage type combi boilers and pellet boilers.
