CORTECO 49357196 NBR BASLRDX7 Rotary Shaft Oil Seal 25x47x7 mm

What is the CORTECO 49357196 Rotary Shaft Seal?

The CORTECO 49357196 is a rotary shaft oil seal (radial shaft seal / simmerring) manufactured from NBR (nitrile butadiene rubber). With dimensions of 25x47x7 mm, it is designed to seal rotating shafts against stationary housings while preventing lubricant leakage and protecting internal components from contamination. The BASLRDX7 design features a right-hand hydrodynamic helix and an integrated dust lip, making it suitable for oil-lubricated applications where reliable sealing and contamination exclusion are required.

Construction and Operating Principle

The CORTECO 49357196 oil seal is engineered to retain lubricant inside the assembly while reducing the ingress of dirt, dust and moisture.

Its construction includes:

• NBR (nitrile butadiene rubber)
• BASLRDX7 sealing profile
• Precision primary sealing lip
• Integrated auxiliary dust lip
• Right-hand hydrodynamic helix
• Rubber-covered outside diameter

During shaft rotation, the hydrodynamic helix assists in returning lubricant toward the sealing lip, while the auxiliary dust lip provides additional protection against external contaminants, helping to extend the service life of both the seal and the shaft.
