EX-WORKS (Incoterms 2020) Seoul, Korea — Buyer arranges freight, duties, and insurance.
FAG NN3028-AS-K-M-SP Cylindrical Roller Bearing is designed for high radial load capacity through line contact between rollers and raceways. It is suitable for rigid, heavy-duty applications such as motors, gearboxes, rolling mills, and machine tools, with N, NU, NJ, and NUP designs offering different axial locating functions.
Cylindrical rollers and a cage are arranged between inner and outer ring raceways. Depending on flange configuration, the bearing can be separable and may support axial load in one or both directions.
Choose the N, NU, NJ, or NUP design by load direction, axial locating requirement, cage material, internal clearance, and lubrication condition.
