Rotary Shaft Seal CORTECO 49358748 39.6x57x8/13 ACM

Applications - reliable rotary sealing for engines and machinery

The rotary shaft seal CORTECO 49358748 is a high-quality oil seal designed for dependable rotary sealing in automotive and industrial systems. It is used as a shaft sealing ring in engines, transmissions, and drive assemblies where continuous rotation, exposure to lubricants, and thermal stability are critical.

Thanks to its precise geometry and robust construction, this technical seal is suitable for compact installation spaces and demanding industrial applications, including powertrain components and mechanical equipment operating under variable loads.

Advantages - high durability and resistance to oils and grease

This rotary oil seal is manufactured from ACM (acrylate rubber), a material widely recognized for its resistance to oils and grease and stable performance at elevated operating temperatures. The BDSLRDSFX6 design ensures consistent contact with the shaft, minimizing leakage and reducing wear over time.

Depending on the application, the seal can perform as a double lip oil seal, offering improved contamination protection compared to a standard single lip oil seal. This makes it suitable for long-term operation in hydraulic and automotive seals systems where reliability and service life are essential.
