V-RING VS 60 NBR - Shaft Sealing Ring

Application of the V-RING VS 60 NBR

The V-RING VS 60 NBR is a flexible shaft sealing ring designed to protect rotating shafts from external contaminants such as dust, dirt, moisture and water. Unlike conventional radial oil seals, the V-RING operates axially on the shaft, sealing against a stationary counterface. This design makes it particularly effective as a protective rotary sealing solution in harsh industrial environments.

The VS 60 model is widely used in industrial applications, including electric motors, gearboxes, pumps, fans, conveyors and machinery assemblies installed in bearing housings. It is commonly applied as an additional technical sealing element that protects bearings and primary shaft seals from premature wear, extending the overall service life of the machine.

Advantages of the VS design and NBR material

The VS profile features a reinforced construction, suitable for higher rotational speeds, increased vibration and demanding operating conditions. Made 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 can compensate for shaft misalignment, axial movement and runout. This significantly improves high durability and operational reliability. The V-RING VS 60 NBR can function as a single-lip seal or as a complementary sealing element supporting other shaft seals, without requiring shaft disassembly during installation.

FAQ - frequently asked questions

What is the purpose of the V-RING VS 60?
It protects rotating shafts and internal machine components from external contaminants.

What is the difference between V-RING VS and VA?
The VS profile has a reinforced design intended for more demanding operating conditions.

Can the V-RING VS 60 replace a standard oil seal?
No, it is mainly used as a protective or auxiliary sealing element alongside a primary oil seal.

How do I select the correct V-RING size?
Selection is based on shaft diameter, for example VS 60 for a 60 mm shaft.

Is NBR suitable for oil environments?
Yes, NBR provides good resistance to oils and greases commonly used in industrial systems.
