6409 AV NILOS Bearing Seal Ring for 6409 Bearings

Heavy-Duty Bearing Protection for Demanding Industrial Environments

The 6409 AV NILOS Bearing Seal Ring is a precision-engineered steel sealing component designed specifically for 6409 series deep groove ball bearings. Developed to improve bearing protection and extend service life, this NILOS ring creates an effective labyrinth sealing system that helps prevent the ingress of dust, dirt, moisture and abrasive particles while reducing lubricant loss during operation.

Widely used throughout industrial maintenance, machine rebuilding and OEM manufacturing, the 6409 AV NILOS ring provides a simple and cost-effective solution for enhancing bearing reliability in challenging operating environments.

Application in Industrial Systems

The 6409 AV NILOS seal ring is commonly used in:

• Industrial conveyors
• Electric motors
• Gearboxes
• Agricultural machinery
• Mining equipment
• Steel processing machinery
• Material handling systems
• Industrial fans
• Production equipment
• Construction machinery
• Bulk handling systems
• Heavy-duty rotating equipment

Its protective design makes it particularly valuable in applications exposed to dust, contamination and continuous operation.

Construction and Design

The AV version is designed as an external sealing ring that operates directly with the outer ring of a bearing to form a highly effective labyrinth seal.
