Anti-Rust and Oil Treatment Process for Rolling Mill Bearings

For large industrial bearings such as FC4866220 four-row cylindrical roller bearings, proper surface protection is essential before shipment and long-term storage. The anti-rust treatment helps maintain bearing quality during transportation and storage.

At WJY Bearing, every bearing receives professional anti-rust oil treatment after final inspection. The process forms a protective layer on the bearing surface to reduce the risk of moisture, oxidation, and corrosion.

After the oil application process, each bearing is carefully wrapped with protective plastic film. This additional protection helps prevent dust, contamination, and environmental impact during delivery.

Through strict manufacturing and packaging procedures, JYHY Group ensures that rolling mill bearings arrive at customers’ facilities in reliable condition and are ready for installation in steel mills, rolling mills, and other heavy industrial equipment.
