3. Technical Description

This NILOS ring is specifically engineered for sealing tapered roller bearings. Manufactured in Germany from special galvanized strip steel, it ensures excellent resistance to wear, corrosion, and environmental contaminants.

Its exterior-sealing design creates a durable sealing edge around the outer bearing ring. This helps maintain lubrication inside the bearing while preventing the intrusion of dirt, dust, moisture, and metal chips—especially critical in industrial applications where contamination leads to premature bearing failure.

NILOS rings are commonly used in applications where standard bearing seals are insufficient or where bearings lack integrated seals.
