Main Description

The CORTECO 01002872 65x90x10 NBR B1SL2 rotary shaft seal is a high-quality oil seal ring designed for reliable rotary shaft sealing in transmissions, axles and industrial drivetrain systems. Engineered for demanding agricultural and mechanical applications, this seal ensures stable lubricant retention and effective contamination protection.

Manufactured from durable NBR (nitrile butadiene rubber), the sealing lip provides excellent resistance to oils, greases and mechanical wear under normal operating conditions. The B1SL2 configuration represents a double lip oil seal with an integrated dust lip, offering enhanced sealing reliability compared to single lip designs. The primary lip retains lubricant inside the housing, while the secondary lip protects against dust, moisture and abrasive particles entering the sealing area.

With dimensions 65x90x10, this shaft seal is commonly used in gearboxes, drive axles and transmission assemblies where dependable technical sealing is essential for long-term performance. The optimized lip geometry maintains consistent contact pressure on the shaft surface, reducing leakage risk and supporting extended maintenance intervals.

This rotary shaft seal is compatible with selected OEM applications from FENDT (OEM reference X554034402000) and ZF (OEM reference 0634309091). As a product of CORTECO, it meets strict quality standards required by professional B2B service operations.

The combination of NBR elastomer and B1SL2 double lip construction ensures high durability, effective oil retention and reliable rotary sealing, making this oil seal a dependable solution for transmission and axle applications.
