CORTECO 20034262 FPM Rotary Shaft Seal 75x100x10 - B1SLRD Oil Seal

Applications of the CORTECO 20034262 Rotary Shaft Seal

The CORTECO 20034262 FPM rotary shaft seal 75x100x10 is a professional oil seal engineered for reliable rotary sealing in demanding industrial and automotive environments. Designed as a shaft sealing ring with an integrated dust lip, it is widely used in gearboxes, transmissions, drive systems and rotating assemblies where effective oil retention and protection against contamination are essential.

This rotary seal is commonly applied in systems compatible with ZF components, including reference numbers 0734319378, 0750111050 and 0750111231. Precise dimensional accuracy ensures a secure fit in the housing, supporting stable sealing performance and reduced risk of leakage during continuous operation.

FPM Material Advantages and High Durability

Manufactured from FPM (FKM fluorocarbon rubber), this technical seal delivers excellent resistance to oils and grease, fuels and many aggressive chemical agents. FPM is the preferred material for applications exposed to elevated operating temperatures and long service intervals, outperforming standard elastomers in harsh conditions.

The B1SLRD design combines a single primary sealing lip with an additional dust lip. This configuration improves protection against external dirt and debris while maintaining low friction at the shaft surface. As a result, the seal offers high durability, reduced shaft wear and consistent performance in heavy-duty industrial applications and hydraulic and automotive seals systems.
