Main description

The CORTECO 01020679 FPM B1BAX1 100x130x12 rotary shaft seal is a professional industrial sealing component designed for demanding applications in front axle wheel hub systems of heavy-duty vehicles. The seal is widely used in MAN F2000 trucks, where reliable shaft and hub sealing is critical for drivetrain durability and operational safety.

This sealing ring is manufactured from FPM (FKM, Viton®), a high-performance fluoroelastomer known for its excellent resistance to gear oils, greases, fuels, elevated temperatures, and ageing. Compared to standard rubber gasket materials such as NBR, FPM offers significantly higher thermal and chemical stability, making it suitable for continuous operation in severe industrial and automotive environments.

The B1BAX1 design is specifically engineered for wheel hub applications, where effective protection against oil leakage and external contamination is essential. The precise lip geometry ensures consistent contact pressure on the shaft surface, contributing to long service life and stable sealing performance. Accurate manufacturing tolerances and fixed dimensions 100x130x12 guarantee correct fitment and reliable installation in OEM-specified housings.

This rotary shaft seal is commonly selected by heavy-vehicle service centers, maintenance departments, and B2B distributors who require repeatable quality, OEM compatibility, and high durability in transport and industrial applications. It supports demanding operating conditions involving fluctuating loads, vibration, and temperature variations.
