Engineered for high RPM stability, extreme temperature resilience, and minimal rotational friction across Daedeok Innopolis laboratories and manufacturing lines.
Strategic technical integration into South Korea's premier science and technology cluster.
Daejeon Metropolitan City serves as the technological heartbeat of South Korea. Centered around Daedeok Innopolis (Daedeok Research and Development Special Zone), Daejeon hosts over 30 government-funded research institutes, including KAIST, Korea Institute of Machinery and Materials (KIMM), and Korea Aerospace Research Institute (KARI), alongside hundreds of advanced technology spinoffs.
The demanding applications in Daejeon—spanning high-speed CNC electro-spindles, semiconductor wafer sorting equipment, biomedical laboratory automation, defense robotics, and satellite attitude control units—require rolling bearings that transcend standard industrial specs. Bearing performance here is measured in micro-inch dimensional runout, vibration acceleration grade (V4/Zv4), and non-contact high-temperature thermal dissipation.
Full spectrum bearing engineering serving Daejeon R&D facilities and global original equipment manufacturers.
Bearings involving: deep groove bearings, self-aligning ball bearings, angular contact ball bearings, thrust ball bearings, cylindrical roller bearing, tapered roller bearings, spherical roller bearings, thrust cylindrical roller bearings, thrust spherical roller bearings, needle roller bearings, cross roller bearings, rolling mill bearings, pillow block bearings, joint bearings, bearing accessories (sleeves and lock nuts) etc.
We can also supply some uncommon bearings such as non-standard bearings, automobile bearings, Mega-bearings, railway bearings, joint bearings, high temperature, super precision bearings, etc.

Combining cost optimization with rigorous ISO/DIN quality standards to deliver high-speed bearing solutions faster and more affordably.
Utilizing vacuum-degassed GCr15 (100Cr6) high-carbon chromium steel, Cronidur 30, and high-purity Silicon Nitride (Si3N4) ceramic rolling elements for extreme wear resistance and non-galling properties under high-frequency friction.
Direct-from-factory pricing removes unnecessary regional distribution markups. South Korean enterprises in Daejeon gain premium-grade performance matching European or Japanese tier-1 brands at a fraction of total procurement cost.
With tailored OEM/ODM capabilities, non-standard dimensions, micro-thin walls, or specialized lubrication coatings can be prototyped in days. Convenient logistics routes ensure fast air or sea delivery directly to Daejeon manufacturing hubs.
Stay ahead of industrial advancements with engineered solutions designed for extreme kinetic demands.
Silicon Nitride ceramic balls feature 40% lower density than steel, reducing centrifugal forces during extreme rotational speeds. Combined with an elastic modulus 1.5 times higher than traditional steel, hybrid bearings minimize heat generation, prevent thermal seizure, and extend relubrication intervals in high-speed CNC spindles.
Integrating Polyfluorinated synthetic greases and non-contact 2RZ/2RS labyrinth seals minimizes torque resistance. This enables high-speed machinery in Daejeon cleanrooms to operate coolly without oil-mist contamination, optimizing energy conversion and extending component lifespan.
Miniature thin-wall flange bearings allow robotic joints and small medical handpieces to achieve higher power density without increasing weight. Edge guard structures prevent axial slippage under dynamic high-speed oscillation.
Replacing standard steel cages with Polyether Ether Ketone (PEEK) or Torlon cages reduces ball pocket friction, withstands aggressive chemical solvents, and remains structurally stable at temperatures up to 250°C during continuous high-RPM activity.
Delivering high-reliability performance tailored for heavy industry, precision electronics, and high-speed automation.
Our bearings are widely used in mechanical equipment, electric power, steel, metallurgy, petroleum, chemical industry, machine tool, textile, automobile, motor, precision instrument, mining machinery, construction machinery, road engineering machinery, railway, etc.
