V-ring NBR

V-ring NBR

V-ring is a specialized seal with a characteristic "V" shape, mainly used in rotary systems where effective protection against contaminants, water, and oils is required. The V-ring provides excellent leak protection, is resistant to high pressure, and variable weather conditions. It is widely used in the automotive industry, machinery, and hydraulics. Ideal for use in shafts, bearings, and other mechanical components.

V-ring type VA NBR - technical specification

V-ring NBR is a high-quality rotary seal that operates axially, rotating with the shaft due to the circumferential clamp. The product consists of three main elements: the sealing lip, the hinge, and the body that ensures stable mounting on the shaft. The V-ring made of NBR rubber is an ideal solution for applications requiring sealing in dusty conditions and "dry" operation.

Advantages:

• Wide range of applications: Suitable for various industrial applications, including hydraulics, pneumatics, and working machinery.

• Low friction coefficient: Due to its low friction coefficient, V-ring NBR allows for high rotational speeds.

• Long lifespan: Characterized by high wear resistance, ensuring prolonged operation.

• Easy installation: A simple assembly process allows for quick and efficient sealing of shafts.

Features:

• NBR working temperature range: from -40°C to +100°C

• NBR rotational speed: ≤ 8 m/s

• NBR pressure: ≤ 0.03 MPa

• Material: NBR (acrylonitrile-butadiene rubber)

• Resistance to substances: Mineral oils, greases, hydraulic fluids, alcohols, silicone greases, hydrocarbons, aliphatic hydrocarbons (e.g., propane, butane, diesel fuel, fuel oils)

Applications:

• Shaft sealing: Protects against contaminants such as dust, dirt, and water from entering mechanical systems.

• External shaft seal protection (simmerring): Provides additional protection for primary seals against dirt.

• Leak sealing: Used in applications requiring prevention of fluid leaks from mechanical circuits.

Limitations:

• Not resistant to: Direct sunlight, ozone, UV radiation, weather conditions.

• Limited resistance to: Polar solvents, non-flammable hydraulic fluids (HFD, HSD), chlorinated aromatic hydrocarbons, glycol-based brake fluids, strong acids, ketones, esters, and aldehydes.

Storage period: 15 years, provided it is stored under appropriate conditions.

V-ring NBR is a reliable rotary seal that ensures high effectiveness in protection against contaminants and leaks in various industrial environments. With excellent resistance to oils and greases, as well as easy installation, it is an excellent solution for a wide range of applications.
