CORTECO 01020465 NBR B1BASL Radial Shaft Oil Seal 68x90x10 mm

Product Overview

The CORTECO 01020465 is a premium-quality radial shaft oil seal designed to provide reliable sealing of rotating shafts in transmissions, gearboxes, differentials, drive systems and industrial machinery. Manufactured by CORTECO, a member of the Freudenberg Group, it meets OEM quality standards and ensures outstanding durability in demanding operating conditions.

Manufactured from NBR (Nitrile Butadiene Rubber), the seal offers excellent resistance to mineral oils, greases and normal operating temperatures. It is ideally suited for automotive and industrial applications where reliable oil retention and contamination protection are essential.

The B1BASL design incorporates a primary sealing lip with a garter spring to maintain constant sealing pressure on the shaft, along with an additional dust lip that prevents dirt, water and other contaminants from entering the assembly. This dual-lip construction significantly extends both seal and component service life.

With dimensions of 68 mm inner diameter, 90 mm outer diameter and 10 mm width, the CORTECO 01020465 is widely used in selected Mercedes-Benz and MAN vehicles, as well as numerous industrial and agricultural applications.
