Construction and Design

The CORTECO 19026779 20x34x9 NBR SCJY is a high-precision radial shaft seal engineered for compact assemblies where reliable sealing is critical. The SCJY design includes an optimized sealing lip and structural reinforcement, ensuring stable operation under dynamic shaft rotation.

Its geometry allows effective oil retention while preventing contaminants such as dust and moisture from entering the system. This makes it particularly suitable for applications where space is limited but performance cannot be compromised.

Industrial Applications

This CORTECO oil seal is widely used in automotive systems, small machinery, and industrial equipment requiring tight sealing tolerances. It is commonly installed in gearboxes, pumps, and drive units where shaft diameters of 20 mm are used.

The SCJY construction is especially effective in environments with moderate pressure and rotational speed, offering consistent sealing performance across a wide range of operating conditions.
