Oil Seal NBR Dichtomatik 130x150x7.5 WASY

Applications

The Oil Seal NBR Dichtomatik 130x150x7.5 WASY is a double-lip radial shaft seal designed for industrial applications where reliable sealing and protection against external contamination are essential. The WASY 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 or humid environments commonly found in industrial operations.

Advantages

The double-lip construction ensures effective retention of lubricants while preventing dust, dirt and moisture from entering the sealing area. The NBR elastomer offers good resistance to mineral oils, greases and standard industrial fluids. A metal-reinforced outer case provides secure seating in the housing, while the integrated garter spring maintains constant lip pressure on the shaft, resulting in stable sealing performance and long service life.
