V-RING VA 50 NBR - Shaft Sealing Ring

Application of the V-RING VA 50 sealing ring

The V-RING VA 50 NBR is a flexible shaft sealing ring designed for effective rotary sealing and protection against external contaminants such as dust, dirt, water and moisture. Unlike conventional radial oil seals, the V-RING operates axially on the shaft and seals against a stationary counterface, making it highly effective in harsh operating environments.

This type of sealing solution is widely used in industrial applications, including electric motors, gearboxes, pumps, fans, conveyors, agricultural machinery and bearing housings. The V-RING VA 50 is often applied as an additional technical sealing element to protect primary oil seals, bearings and lubricated components from premature wear and contamination.

Advantages of VA design and NBR material

Manufactured from high-quality NBR (nitrile butadiene rubber), the V-RING VA 50 offers very good resistance to oils and greases, excellent elasticity and stable performance under typical industrial conditions. The VA profile allows fast and simple installation directly on the shaft, without the need to dismantle the shaft or the entire assembly, which is especially important in maintenance and service operations.

Because the V-RING seals axially rather than radially, it can compensate for shaft misalignment, axial movement and vibrations. This design significantly improves high durability and extends the service life of both the sealing system and the protected machine components. The V-RING VA 50 can function as a single-lip seal or as a complementary sealing element in more complex shaft sealing arrangements.

FAQ - frequently asked questions

What is a V-RING used for?
A V-RING protects rotating shafts and machine interiors from dust, water and external contaminants.

How does a V-RING differ from a standard oil seal?
A V-RING seals axially and mainly provides protective sealing, while a standard oil seal seals radially and retains lubricants.

How do I select the correct V-RING size?
Select the size according to the shaft diameter, for example VA 50 for a 50 mm shaft.

Can a V-RING operate in oily environments?
Yes, NBR material provides resistance to oils and greases, but the V-RING does not replace a primary oil seal.

Is the VA 50 suitable for industrial use?
Yes, it is commonly used in industrial and mechanical applications.
