HANKOOK MATERIAL Co., Ltd. is a company that has grown into a company through mainly producing oilless bearings and worm wheels using brass and bronze as the main materials among non-ferrous castings.
HANKOOK MATERIAL has a foundry and processing facility, and based on its strength of being able to produce everything from materials to finished products, it has achieved excellent material and mechanical property management.
HANKOOK MATERIAL is thus supplying its products to prominent companies in Japan, India, Germany, and some EU countries, and has achieved excellent supplier evaluations every year.

Oilless Bearings
HANKOOK MATERIAL’s oilless bearings are suitable for areas where refueling is impossible or ineffective due to high loads, low speeds, corrosive environments, foreign matter inflow, impact loads, and structural constraints. This product improves machine performance, reduces manpower and costs caused by refueling, and enhances productivity.
Oilless bearings are mainly used in environments where high loads and low speeds are applied; where the machine cannot stop for refueling; where there is a huge loss; where personnel cannot refuel directly; where corrosion is likely; and in underwater applications.

Worm Wheels
HANKOOK MATERIAL’s worm wheels are supplied with shafts to various domestic heavy machine attachment companies. The company has currently developed its own worm wheel material called KOB3, which has the most suitable mechanical properties for heavy machine attachments, and is developing overseas markets with competitive unit prices.
Worm wheels are mainly used in heavy machine attachments such as rotators and tilt rotators, and are used in applications where various power transmissions are required.

[INQ. NO. 2507M32] Geum Yeong Metal’s oilless bearings are dry (self-lubricating) bearings manufactured by precisely embedding a special solid lubricant into a metal base. Designed to maintain stable lubrication performance over long periods without the use of oil or grease, these bearings release microscopic particles from the embedded solid lubricant during friction, forming thin lubricating film on the contact surface. This reduces wear and enables smooth operation.
Thanks to this structure, Geum Yeong Metal’s oilless bearings demonstrate excellent wear resistance and self-lubricating performance ― even under tough conditions for lubrication such as high loads, high temperatures, underwater environments, and exposure to chemicals. They are suitable for industrial environments as they require limited maintenance, and can be effectively applied to equipment resisting oiling.
The oilless bearings are used in various fields such as press dies, industrial machinery, construction equipment, offshore plants, food equipment, cleaning equipment, and equipment for underwater and chemical environments.

Metal Bushes
A metal bush is a component made from various metal materials such as steel and high-strength brass. It is commonly used at industrial sites requiring high strength, durability, and wear resistance. It delivers stable performance even under high-load and high-speed rotation conditions. Geum Yeong Metal’s metal bushes can be customized according to usage conditions by applying various bronze-based alloys.

Their product surfaces feature precisely done oil grooves. This structure maintains the uniform distribution of lubricant and forms a consistent lubricant layer on the friction surface, thereby reducing wear. Additionally, the oil groove structure enhances operational stability, even in environments where external contaminants may enter, thus contributing to smooth lubrication maintenance of the equipment.
Geum Yeong Metal’s metal bushes not only have excellent wear resistance, but also strong corrosion resistance. Through high-strength materials and corrosion-resistant treatment, they are protected from various corrosion factors such as moisture, water, and chemicals. Thanks to these characteristics, they are applied to various fields such as industrial machinery, ship equipment, press molds, and construction equipment.
Geum Yeong Metal specializes in the manufacturing and wholesale distribution of machinery, mold parts, and various oil-free friction B/R products. The company is dedicated to providing high-quality products quickly and at more competitive prices.

[INQ. NO. 2106M02] GABSAN METAL Co., Ltd. is a company that specializes in parts and materials. The company has been manufacturing nonferrous cast products for 30 years since 1990. The company manufactures copper special alloy products, such as Cu, Pbc, Bsc, Bc, Albc, and Hbsc.
The materials and parts manufactured by GABSAN METAL are used for the parts that function as bearings in the rubbing parts of steel manufacturing facilities, industrial machines (hydraulic press, forge press, extruders, catapults, shearing machine, cutters, lathes, milling machine, boat winches), ships, pot bearing for railway bridge seats, mold material, heat exchanger plates, hydraulic cylinder parts, etc.

Oilless bearings
Bearings are parts that support the shaft and reduce friction by being installed on the rotational and linear sliding parts of industrial machinery.
By pressing solid lubricant into the metal base material to supply lubricant to the friction surface, fine particles of the solid lubricant and the lubricant contained in the solid lubricant form a lubricating film during frictional motion.
Bearings that perform self-lubricating function even in a non-lubricating state are called oilless bearings.

Worm gear
The worm gear is the main part of the reduction gear that transmits power by lowering the rotational speed between the two shafts.
Used for various purposes such as traction machines for elevators, general industrial reducers, and worm gears in actuators

Bush
The bush (metal bearing) is mounted on the rotating part of industrial machinery to help supply lubricant.
A metal bearing that absorbs frictional heat generated by machine rotation, helps smooth frictional motion, prevents wear of parts, and helps precise machine operation.
