PRODUCT DESCRIPTION / OVERVIEW
Advantage of the AV type ring:
- Provides effective axial sealing by combining metal construction with elastomer elements to protect bearings from dust, dirt, and moisture.
- Maintains excellent grease retention inside the bearing, ensuring consistent lubrication and extended service life.
- Flexible sealing lip compensates for minor misalignment and shaft movement, improving sealing reliability.
- Reduces ingress of contaminants in harsh operating environments where standard metal rings may be insufficient.
- Compact design allows easy integration into existing bearing arrangements without requiring additional space.
- Suitable for moderate rotational speeds while providing improved sealing performance with minimal friction.
- Cost-effective solution for applications requiring enhanced protection against both solid and light liquid contaminants.

FAQs
A NILOS-RING is an all-metal labyrinth seal designed to protect rolling bearings from contaminants such as dust, dirt, and abrasive particles. It rotates with the bearing and forms a tight barrier that prevents the ingress of harmful materials without grease loss.
Main types include AV rings that seal the outer raceway, JV rings for the inner raceway, and combination ZAV/ZJV rings offering dual sealing. Custom profiles are also manufactured for specialized applications.
NILOS-RING products are widely used in Cement, mining, construction, agriculture, pulp and paper, automotive, and other industries where bearings are exposed to harsh contaminants.
By preventing the ingress of abrasive dust, dirt, and slurry, NILOS-RINGS reduce wear and corrosion, thereby significantly extending bearing service life compared to conventional seals.
Yes, NILOS-RINGS are compact and designed for easy retrofit installation without requiring housing redesign or bearing modification.
