Rotary Shaft Seal V-RING VA 400 NBR 400x420x12 Oil Seal

High Performance V-RING Seal for Rotating Shaft Protection

The V-RING VA 400 NBR 400x420x12 shaft seal ring is a high-quality axial elastomer seal designed to protect rotating shafts, bearings and drive systems against dust, dirt, water and other external contaminants. Manufactured from premium NBR nitrile rubber, it provides excellent flexibility and maintains reliable sealing performance over a wide range of operating conditions.

Unlike conventional radial shaft seals, a V-RING rotates together with the shaft while the sealing lip contacts a stationary counterface. This unique design creates an effective barrier that prevents contaminants from reaching bearings, housings and lubrication systems, significantly extending the service life of industrial machinery.

The VA profile is the most widely used V-RING design and is suitable for numerous industrial, agricultural and OEM sealing applications.

FAQ

What is a V-RING seal used for?

A V-RING seal protects rotating shafts, bearings and sealing systems from dust, dirt, water and other external contaminants.

How does a V-RING differ from a radial shaft seal?

A V-RING rotates together with the shaft and seals axially against a stationary surface, while a radial shaft seal seals directly against the shaft.

Why is NBR used for this seal?

NBR offers excellent resistance to mineral oils, greases, abrasion and ageing, making it ideal for industrial sealing applications.

Can a V-RING be used together with an oil seal?

Yes. It is frequently installed as an auxiliary seal to extend the service life of radial shaft seals and bearings.

Is installation complicated?

No. The flexible one-piece design allows fast installation without special tools.
