Oilless Bearings

July 21, 2025 by Leave a Comment
https://korean-machinery.com///inquiry

[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.
