2. Product Properties

• Type: NILOS sealing ring – interior type
• Sealing Method:
• Forms a contact/labyrinth seal on the inner ring of the tapered roller bearing
• Designed to protect the bearing from contamination entering from the inner diameter side
• Material Advantages:
• High-strength galvanized spring steel
• Very good corrosion resistance
• Excellent mechanical durability
• Function:
• Protects the bearing from dust, dirt, humidity, and metallic particles
• Helps retain lubricant inside the bearing
• Extends bearing service life, especially in harsh conditions

3. Technical Description

This NILOS ring is engineered specifically for interior sealing of tapered roller bearings.
Its sealing lip is pressed against the inner bearing ring, forming an effective barrier against contamination while preventing lubricant escape.

Manufactured in Germany, this NILOS ring uses galvanized strip steel, ensuring exceptional resistance to corrosion and long-lasting durability—even in demanding industrial environments.

Interior-sealing NILOS rings are particularly useful when tapered roller bearings are exposed to contaminants near the shaft side or in applications where environmental debris can enter from the inside.

4. Typical Applications
