Main Description

The CORTECO 01002933 50x62x7 NBR B1 A rotary shaft seal (82002933) is a precision-engineered single lip oil seal designed for reliable rotary shaft sealing in demanding mechanical and automotive applications. This version features a metal outer case, ensuring secure positioning in the housing where high retaining forces may push the seal out of its seat.

Manufactured from durable NBR (nitrile butadiene rubber), the sealing lip provides excellent resistance to oils, greases and mechanical wear, making it suitable for engines, gearboxes and industrial drive systems. The B1 A construction represents a single lip design with full metal outer surface, optimized for applications requiring enhanced mechanical stability and accurate housing fit.

With dimensions 50x62x7, this shaft seal is commonly used in transmission systems, engine assemblies and rotating components where dependable technical sealing is essential. The metal outer surface improves structural rigidity and supports installation in housings exposed to mechanical stress. The seal is designed for operating pressures up to 0.05 MPa, making it appropriate for controlled pressure environments.

This oil seal is compatible with selected OEM applications from MAN (OEM reference 06562790046), confirming its suitability for professional service and maintenance operations in commercial vehicles and industrial machinery.

As a product of CORTECO, the seal meets strict quality standards required by professional B2B customers.
