CORTECO 12011113 Rotary Shaft Seal 17x35x7/9 NBR BASL

Applications

The CORTECO 12011113 Rotary Shaft Seal (17x35x7/9 mm) is a precision-engineered oil seal designed to prevent oil leakage and contamination in rotating shafts and housings.
Manufactured by CORTECO, a trusted global supplier of sealing solutions, this model uses NBR (nitrile rubber) and a BASL-type construction, ensuring long service life and excellent resistance to oils, greases, and fuels.

It is suitable for industrial machinery, automotive engines, gearboxes, and drive shafts, where reliable shaft sealing is essential for maintaining performance and reducing maintenance downtime.

Advantages

• Material: NBR (Nitrile Rubber) - ensures high resistance to oils, lubricants, and wear, ideal for medium-temperature applications.

• BASL Design (Double Lip) - enhanced sealing efficiency, combining a primary sealing lip with a dust lip to protect against dirt and debris.

• Dimensions 17x35x7/9 mm - designed for perfect fit in standard housings and bearing units.

• Reliable oil sealing - prevents lubricant loss and contamination, ensuring smooth shaft operation.

• Suitable for heavy-duty use - preferred by engineers for both industrial and automotive sealing systems.
