V-RING VA 18 NBR Shaft Seal Ring

Compact V-RING Seal for Reliable Rotating Shaft Protection

The V-RING VA 18 NBR shaft seal ring is a high-quality axial elastomer seal designed to protect rotating shafts, bearings and drive systems from dust, dirt, water, mud and other external contaminants. Designed for shafts with a nominal diameter of 18 mm, this flexible seal rotates together with the shaft while maintaining continuous contact with a stationary counterface, creating an effective sealing barrier.

Manufactured from premium NBR nitrile rubber, the VA 18 seal combines excellent flexibility with outstanding resistance to mineral oils, greases and mechanical wear. Its simple one-piece construction enables fast installation without special tools, making it an ideal sealing solution for industrial maintenance, OEM manufacturing and machinery rebuilding.

V-RING seals are widely used as auxiliary seals to extend the service life of radial shaft seals, deep groove ball bearings, self-aligning ball bearings, spherical roller bearings and complete bearing assemblies.

Application in Industrial Systems

The V-RING VA 18 NBR seal is commonly used in:

• Rotating shafts
• Electric motors
• Bearing housings
• Industrial gearboxes
• Pumps
• Fans and blowers
• Conveyor systems
• Agricultural machinery
• Food processing equipment
• Packaging machinery
• Production equipment
• Material handling systems

It is particularly effective in preventing contaminants from reaching bearings and lubrication systems in demanding industrial environments.

Construction and Design

The VA profile is the most widely used V-RING design, offering efficient axial sealing with minimal friction.

Key construction features include:

• VA profile
• Flexible sealing lip
• Axial sealing principle
• Self-adjusting shaft fit
• One-piece elastomer construction
• Low friction operation
• Compact installation design
• Quick installation and replacement

The seal automatically follows shaft movement while maintaining consistent contact with the counterface for reliable sealing performance.

Material Properties

The seal is manufactured from high-quality NBR nitrile rubber, providing excellent performance in industrial operating conditions.

Material advantages include:

• Excellent resistance to mineral oils
• High resistance to greases
• Good resistance to fuels
• Excellent abrasion resistance
• High elasticity
• Good ageing resistance
• Reliable sealing performance
• Long operational life

NBR is one of the most commonly specified sealing materials for industrial shaft sealing applications due to its excellent balance of durability, flexibility and chemical resistance.
