Technical Specifications

Product Description

The CORTECO 19026836 HNBR SCJY rotary shaft seal is engineered to provide dependable sealing performance in high-demand automotive applications. The spring-loaded primary sealing lip maintains constant contact with the rotating shaft to minimize lubricant leakage, while the auxiliary dust lip protects the sealing area from dirt, moisture and abrasive particles.

Manufactured from HNBR, the seal offers significantly improved resistance to heat, oxidation and ageing compared with conventional NBR compounds. It also provides excellent compatibility with mineral oils, transmission fluids and many automotive lubricants, making it ideal for steering systems, gearboxes and other drivetrain components operating under elevated temperatures.
