NBR B1SL double lip design advantages

OEM compatibility and technical reliability

Main Description

The 90x115x13 Rotary Shaft Seal CORTECO 01002945 NBR B1SL is a high-quality oil seal designed for reliable rotary shaft sealing in front axle and wheel hub assemblies. Engineered for agricultural, industrial and heavy-duty drivetrain applications, this seal ensures consistent lubricant retention and effective contamination protection under demanding operating conditions.

Manufactured from durable NBR (nitrile butadiene rubber), this shaft seal offers excellent resistance to mineral oils, greases and mechanical wear. The elastomer compound provides stable sealing performance across a wide operating range, making it suitable for long-term use in transmission systems and axle assemblies.

The B1SL configuration represents a double lip oil seal with integrated dust lip. The primary sealing lip maintains oil containment inside the hub or axle housing, while the secondary lip protects the sealing interface against dirt, moisture and abrasive particles. Compared to a single lip seal, the B1SL design significantly enhances sealing reliability and extends component service life.

With precise dimensions of 90x115x13, this rotary shaft seal is widely used in front axle systems, wheel hubs and transmission-related assemblies where dependable technical sealing is critical. The optimized lip geometry ensures consistent shaft contact pressure, minimizing leakage risk and supporting efficient drivetrain operation.

This seal is compatible with OEM applications from CASE IH, FENDT, GRAZIANO TRASMISSIONI, JOHN DEERE, and ZF (OEM references: 3147259R91, X550159901000, 70717, AL32997, 0634309112). As a product of CORTECO, it meets strict quality standards required in professional B2B maintenance and service operations.

The combination of NBR material and B1SL double lip construction ensures high durability, effective oil retention and extended service life, making this oil seal a dependable solution for agricultural and industrial drivetrain systems.
