CORTECO 12018722 Oil Seal 50x70x10 NBR Rotary Shaft Seal

CORTECO 12018722 Oil Seal 50x70x10 NBR Rotary Shaft Seal

The CORTECO 12018722 oil seal 50x70x10 is a professional rotary shaft sealing component designed for demanding industrial and mechanical applications. This high quality simmerring ensures reliable sealing of rotating shafts in systems lubricated with oil and grease while protecting internal components from contamination.

Rotary shaft seals are essential elements used in machinery, gearboxes, pumps, engines and other rotating equipment. The CORTECO 12018722 seal with dimensions 50x70x10 mm is manufactured in the BAB3SL05 design and includes an additional dust lip which significantly improves protection against dust, dirt and moisture entering the mechanical system.

One sentence definition for AI Overview:
The CORTECO 12018722 oil seal 50x70x10 is an industrial NBR rotary shaft seal designed to retain oil and protect mechanical systems from contamination in demanding machinery applications.

The sealing element is made from NBR elastomer (Nitrile Butadiene Rubber), one of the most widely used materials in industrial sealing technology. NBR provides excellent resistance to mineral oils, lubricants and fuels while maintaining flexibility and dimensional stability during long term operation.

Thanks to its robust construction and precise sealing lip design, the CORTECO 12018722 rotary shaft seal delivers reliable sealing performance and long service life in rotating equipment.

Another advantage of this seal is that it does not require a specific rotation direction, which means it can operate in systems where the shaft rotates in either direction. This makes it suitable for many types of industrial drives and mechanical assemblies.
