AV
Designates a NILOS ring used for external sealing of open bearings.
The sealing edge contacts the outer ring of the bearing.
Protects from dust, debris, moisture, and contamination entering from the exterior side.
3. Product Properties
Type: NILOS Ring – External Sealing (AV Type)
Material: Special galvanized strip steel
Designed For:
Externally sealing open bearings, specifically tapered roller bearings and deep groove bearings of the 32004 series
Function:
Creates a press-fitted sealing lip against the outer ring
Prevents contaminants from entering the bearing
Retains lubrication and extends bearing service life
Load Handling:
Provides sealing only (not load-bearing)
Works in conjunction with the bearing’s natural load capacity
Typical Temperature Suitability: Compatible with most industrial environments and lubricants
4. Technical Description
The NIL32004XAV is a high-quality NILOS ring manufactured by NILOS GmbH & Co (Germany), designed to provide external sealing protection for open bearings in the 32004 tapered roller bearing series.
Constructed from special galvanized strip steel, this sealing ring offers excellent:
Corrosion resistance
Mechanical durability
Long-term sealing reliability
The AV-type NILOS ring fits tightly over the outer bearing ring, forming a resilient sealing edge that shields the bearing from dust, dirt, moisture, and metal particles. This is especially crucial in harsh industrial environments where open bearings are exposed to contaminants that can shorten service life.
5. Typical Applications
Industrial Equipment
Gearboxes
Conveyor systems
Mechanical drives
Pumps
