Rotary Shaft Seal CORTECO 12015338 NBR BASFX27 Oil Seal 28x39,64x6,35

Applications of the CORTECO Rotary Shaft Seal

The CORTECO 12015338 NBR BASFX27 rotary shaft seal is a precision-engineered oil seal designed for reliable sealing of rotating shafts in demanding industrial and automotive applications. Its compact dimensions of 28x39.64x6.35 make it ideal for assemblies where installation space is limited and consistent sealing performance is required.

This shaft sealing ring is commonly used in:

• industrial machinery and power transmission systems,

• gearboxes and compact reducers,

• automotive and engine-related assemblies,

• hydraulic units and technical equipment requiring stable rotary sealing.

The BASFX27 profile represents a single lip oil seal, optimized for controlled operating conditions where effective oil retention and reduced friction are critical.

Advantages of the NBR Oil Seal BASFX27

Manufactured from NBR (nitrile butadiene rubber), this technical seal offers excellent resistance to oils and grease, ensuring long service life and consistent sealing performance. NBR is widely recognized in the sealing industry for its balance of elasticity, durability, and chemical resistance.

Key advantages include:

• high durability in continuous operation,

• effective rotary sealing under stable loads,

• resistance to mineral oils and lubricants,

• precise manufacturing quality from CORTECO,

• reliable performance in industrial environments.

This rotary oil seal is designed to minimize leakage while maintaining low wear on the shaft surface.
