Oil Seal 220x250x15 NBR WAS DICHTOMATIK

Applications

The Oil Seal 220x250x15 NBR WAS Dichtomatik is a double-lip radial shaft seal designed for demanding industrial applications where reliable sealing and protection against contamination are required. It is commonly used in gearboxes, reducers, pumps, electric motors, industrial machinery and drive systems.
The WAS design, featuring an additional dust lip, makes this seal particularly suitable for dusty, dirty and industrial environments where standard single-lip seals may be insufficient.

Advantages

The double-lip construction ensures effective sealing of lubricants while simultaneously protecting the shaft area from external contaminants. The NBR elastomer provides good resistance to mineral oils, greases and typical industrial media. A metal outer case guarantees stable seating in the housing, while the integrated garter spring maintains consistent lip pressure on the shaft, resulting in long service life and reduced risk of leakage.

Main description

The Oil Seal 220x250x15 NBR WAS Dichtomatik is a high-quality technical sealing solution developed for industrial shaft applications requiring durability and operational reliability. As a double-lip oil seal, it combines a primary sealing lip responsible for retaining oil and grease with a secondary dust lip that protects the sealing system from external dirt, dust and moisture. This construction significantly improves the operational lifespan of machinery components.

The NBR sealing lip offers proven resistance to mineral oils, lubricants and commonly used industrial fluids. Combined with a rigid metal outer ring, the seal maintains dimensional stability and secure housing fit, even under continuous operation and varying rotational speeds. The spring-loaded lip design ensures constant radial pressure on the shaft, supporting consistent sealing performance over time.

With its standard 220x250x15 mm dimensions, this radial shaft seal is widely used for maintenance, replacement and OEM applications. It is suitable for industrial transmissions, mechanical drive units and general machinery where effective shaft sealing and contamination protection are essential. The oil seal meets the expectations of B2B customers seeking reliable, repeatable and technically sound sealing components for industrial use.
