Oil Seal NBR 50x80x13 WAS Dichtomatik

Applications

The Oil Seal NBR 50x80x13 WAS Dichtomatik is a double-lip radial shaft seal designed for industrial applications where reliable oil retention and protection against external contamination are required. The WAS design, featuring a primary sealing lip and an additional dust lip, is widely used in gearboxes, pumps, electric motors, production machinery and drive systems. It is particularly suitable for dusty environments and variable operating conditions.

Advantages

The double-lip construction provides stable and long-lasting sealing performance, effectively preventing oil and grease leakage while protecting the shaft area from dust and dirt. The NBR elastomer offers good resistance to mineral oils, greases and standard industrial fluids. A metal-reinforced outer case ensures secure seating in the housing, while the integrated garter spring maintains constant lip pressure on the shaft, resulting in high durability and reliable operation.
