EX-WORKS (Incoterms 2020) Seoul, Korea — Buyer arranges freight, duties, and insurance.
INA GE70-DO-2RS Spherical Plain Bearing is a sliding-contact bearing that allows oscillating motion and misalignment. It supports high radial and changing-direction loads, making it suitable for hydraulic cylinders, linkages, construction machinery, and agricultural joints.
A spherical inner ring slides against a matching spherical outer ring. Maintenance-required, maintenance-free, and sealed designs can be selected according to load, speed, and service conditions.
Check load direction, oscillation angle, relubrication access, sealing need, ring material, and mounting dimensions.
