V-RING VS 20 NBR - Shaft Sealing Ring

Application of the V-RING VS 20 NBR

The V-RING VS 20 NBR is a flexible shaft sealing ring designed to protect rotating shafts against external contaminants such as dust, dirt, water and moisture. Unlike conventional radial oil seals, the V-RING operates axially on the shaft, sealing against a stationary counterface and providing effective rotary sealing in harsh operating conditions.

This sealing solution is widely used in industrial applications, including electric motors, gearboxes, pumps, conveyors, fans and machinery assemblies installed in bearing housings. The V-RING VS 20 NBR is frequently applied as a protective sealing element that shields bearings and primary oil seals from premature wear and contamination.

Advantages of the VS design made from NBR

The VS profile features a reinforced construction, making it suitable for higher rotational speeds and increased vibration levels. Manufactured from NBR (nitrile butadiene rubber), the sealing ring offers very good resistance to oils and greases, stable mechanical properties and reliable performance in typical industrial temperature ranges.

Because the V-RING seals axially rather than radially, it effectively compensates for shaft misalignment, axial movement and runout. This significantly improves high durability and extends the service life of the entire sealing system. The V-RING VS 20 NBR can function as a single-lip seal or as a complementary sealing element supporting other shaft seals without requiring shaft disassembly during installation.
