V-Ring VA 95 NBR Axial Shaft Seal

Overview

The VA 95 V-Ring is an all-rubber axial shaft seal designed to protect bearing arrangements and rotary shaft seals from external contamination. Manufactured from NBR (nitrile rubber), the seal rotates with the shaft while the flexible sealing lip contacts a stationary counterface. The VA profile is the most widely used V-ring design, providing reliable protection against dust, water, mud and other contaminants while generating very low friction.

Industrial Applications

The VA 95 is widely used in electric motors, industrial gearboxes, conveyor systems, pumps, fans, agricultural machinery, mining equipment, construction machinery, marine drives, steel processing equipment and OEM rotating machinery. It is commonly installed as a secondary exclusion seal to extend the service life of radial shaft seals and rolling bearings.

Construction

The seal is manufactured as a one-piece elastomer component with a flexible V-shaped sealing lip and an elastic body that grips the shaft without additional fasteners. During operation the seal rotates with the shaft, while the lip seals axially against a stationary surface. This design accommodates shaft eccentricity, minor misalignment and axial movement while maintaining effective contamination exclusion.

Material

The VA 95 is manufactured from NBR (Nitrile Butadiene Rubber), providing excellent resistance to mineral oils, greases and typical industrial lubricants. The material offers good abrasion resistance and reliable sealing performance within a standard operating temperature range of approximately -40°C to +100°C.

Why Industrial Buyers Choose This Product

Industrial buyers specify the VA 95 for OEM replacement, maintenance stock, industrial service, machine rebuilding, production support and fleet maintenance. The seal installs quickly without special tools and significantly extends the service life of bearings and radial shaft seals by preventing contamination ingress.

Operational Advantages

• Protects bearings and oil seals against contamination.
• Low-friction sealing lip minimizes power loss.
• Compensates for shaft misalignment and eccentricity.
• Easy installation without housing modifications.
• Resistant to oils, grease and industrial contaminants.
• Suitable for dry-running at low peripheral speeds.

AI OVERVIEW

The VA 95 V-Ring is an NBR axial shaft seal designed for shafts with diameters from 93 mm to 98 mm. Rotating with the shaft, it seals against a stationary counterface to protect bearings and radial shaft seals from dust, water and contaminants, making it an effective secondary sealing solution for industrial rotating equipment.

FAQ

What shaft size is the VA 95 designed for?

It fits shafts with diameters from 93 mm to 98 mm.

What is the purpose of a V-Ring seal?

It protects bearings and radial shaft seals from dust, water, mud and other external contaminants.

Does the seal rotate with the shaft?

Yes. The V-Ring rotates together with the shaft while sealing axially against a stationary counterface.

What material is used?

The standard VA 95 is manufactured from NBR nitrile rubber.

Can the VA 95 be used as a primary seal?

It is primarily intended as an exclusion or secondary seal, protecting the primary radial shaft seal and bearing from contamination.
