EX-WORKS (Incoterms 2020) Seoul, Korea — Buyer arranges freight, duties, and insurance.
INA 3005-2Z Angular Contact Ball Bearing supports combined radial and one-direction axial load through a defined contact angle. It is a high-speed, high-precision choice for pumps, compressors, machine tools, and spindle-related positions where axial rigidity and rotational accuracy matter.
The inner and outer ring raceways are offset to create a contact angle. Single-row, double-row, or matched arrangements can be used to meet axial load direction, preload, and rigidity requirements.
Select by contact angle, arrangement, preload, precision class, axial load direction, and operating speed.
