Main Description

The CORTECO rotary shaft seal 01034641B is a professional-grade oil seal engineered for sealing rotating shafts in manual gearboxes, heavy-duty vehicles, and demanding industrial applications. This shaft sealing ring ensures reliable protection against gearbox oil leakage while preventing dust, moisture, and abrasive particles from entering the transmission housing.

Manufactured from FPM (fluoroelastomer), the seal provides excellent resistance to oils and grease, elevated temperatures, and aggressive operating conditions. Compared to standard elastomers, FPM offers superior aging resistance and dimensional stability, making this rotary seal suitable for long-term operation in automotive and industrial drivetrains.

The seal features a double lip oil seal design (TC type) with an additional dust lip, enhancing sealing efficiency and extending shaft and gearbox service life. This construction delivers stable rotary sealing performance even under continuous operation and variable load conditions. The variable sealing profile allows precise shaft contact and compensates for minor installation tolerances, which is especially important during gearbox service and overhaul.

The CORTECO 01034641B oil seal is widely used in manual transmission systems, including applications in RENAULT TRUCKS, as well as in industrial machinery where high durability and reliable shaft sealing are critical. Common English search terms associated with this product include CORTECO rotary shaft seal, gearbox oil seal 55x70, double lip oil seal FPM, and rotary oil seal for manual transmission.
