CORTECO 12011049 Rotary Shaft Seal 95x125x12 NBR BA

Applications - Reliable Sealing for Industrial and Automotive Systems

The CORTECO 12011049 rotary shaft seal 95x125x12 is a precision engineered oil seal designed for demanding industrial applications and automotive systems. Frequently searched under terms such as rotary shaft seal 95x125x12, CORTECO oil seal 12011049, NBR BA shaft seal, and double lip oil seal 95x125x12, this model is widely used where secure rotary sealing is essential.

This shaft sealing ring is suitable for gearboxes, heavy duty transmissions, pumps, reducers, and engine assemblies. As a rotary seal, it prevents leakage of lubricants while protecting internal components from dust and contamination. It is commonly selected as an engine seal and as part of hydraulic and automotive seals in medium temperature operating environments.

Advantages - BA Double Lip Design and NBR Performance

The BA design features a primary sealing lip with a garter spring and an additional dust lip. This double lip oil seal construction improves contamination protection compared to a single lip oil seal, extending service life in real working conditions.

Manufactured from NBR (nitrile rubber), the seal provides excellent resistance to oils and grease, including mineral based lubricants. NBR material ensures high durability, stable elasticity, and reliable sealing performance under dynamic shaft rotation.

The external metal reinforced structure enhances dimensional stability and ensures secure seating in the housing. This technical seal is designed for consistent contact pressure and reduced wear, supporting long term operational reliability.
