NBR B2SL double lip design advantages

Technical specifications and OEM compatibility

Main Description

The CORTECO 01003701 110x140x13 NBR B2SL rotary shaft seal is a high-quality oil seal engineered for reliable rotary shaft sealing in wheel hubs, transmissions and heavy-duty drivetrain systems. Designed for commercial vehicles and industrial machinery, this seal ensures effective lubricant retention and protection against contamination.

Manufactured from durable NBR (nitrile butadiene rubber), the sealing lip provides excellent resistance to mineral oils, greases and mechanical wear under standard operating conditions. The B2SL configuration represents a double lip oil seal with an integrated dust lip, offering improved sealing performance compared to single lip designs. The primary lip retains lubricant inside the hub or gearbox housing, while the secondary lip prevents dust, moisture and abrasive particles from entering the sealing area.

With precise dimensions of 110x140x13, this shaft seal is commonly used in wheel hub assemblies and drivetrain components where dependable technical sealing is essential. The optimized lip geometry maintains consistent contact pressure on the shaft surface, minimizing leakage risk and supporting long service intervals.

This oil seal is compatible with selected OEM applications from ZF Automotive (OEM 0634309209), Elring (OEM 10542200), MAN (OEM 06562890236) and Goetze (OEM 5030579300). As a product of CORTECO, it meets strict quality standards required in professional B2B maintenance and service operations.

The combination of NBR elastomer and B2SL double lip construction ensures high durability, reliable oil retention and effective contamination protection, making this rotary shaft seal a dependable solution for wheel hub and transmission applications.
