V-RING VA 40 NBR - Shaft Sealing Ring

Application of the V-RING VA 40 sealing ring

The V-RING VA 40 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 traditional radial oil seals, the V-RING operates axially on the shaft and seals against a stationary counterface, making it highly effective in harsh working environments.

This solution is widely used in industrial applications, including electric motors, gearboxes, pumps, fans, conveyors, agricultural machinery and bearing housings. The V-RING VA 40 is often applied as a secondary technical sealing element to protect primary shaft seals, bearings and lubrication systems from contamination and premature wear.

Advantages of the VA design and NBR material

Manufactured from high-quality NBR rubber, the V-RING VA 40 offers good resistance to oils and greases, excellent elasticity and stable performance over a wide operating temperature range. The VA profile allows quick and easy installation directly on the shaft without the need to dismantle the entire assembly, which is especially valuable during 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 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 an oil seal seals radially and retains lubricants.

How do I select the correct V-RING size?
Choose the size according to the shaft diameter, for example VA 40 for a 40 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 40 suitable for industrial use?
Yes, it is commonly used in industrial and mechanical applications.
