Rotary Seals

Rotary Seals

Rotary shaft seals, also known as oil seals or simmerings, are designed to seal rotating elements such as shafts or spindles in mechanical systems. Their primary role is to retain lubricants within the housing while preventing external contaminants—such as dust, water, and other fluids—from entering the system.

These seals are critical in protecting bearings and ensuring the proper function and longevity of components operating under rotational motion.

Applications:

Rotary shaft seals are widely used in:

  • Gearboxes

  • Electric motors

  • Pumps

  • Hydraulic and pneumatic actuators

  • Automotive steering systems

  • Industrial machinery

Available Types:

We offer a broad selection of rotary seals tailored to various technical requirements, including:

  • Corteco® Simmerings – Premium radial shaft seals with high-performance elastomers

  • Pressure-resistant seals (BABSL, BAHD, BAHDSN) – Designed for applications with internal pressures up to several bar

  • ASL-type seals – Developed specifically for steering gears and other high-speed applications

  • DIN-standard seals (DIN 3760 / DIN 3761) – Universally compatible industrial shaft seals

Material Options:

Rotary shaft seals are made from high-performance materials depending on the application:

  • NBR (Nitrile Rubber): Excellent resistance to oil, fuel, and wear; ideal for general-purpose sealing

  • FPM/FKM (Viton®): Superior resistance to heat, chemicals, and aging

  • ACM, HNBR, and PTFE options – Available for demanding applications with high temperatures or aggressive media

The seal body may incorporate a metal insert for structural rigidity, and the sealing lip may include a spring for improved contact pressure against the shaft (e.g., with or without a garter spring).

Design Variants:

  • Single or double lip configurations

  • With or without dust lip

  • Outer rubber-coated or metal-cased bodies

  • Seals with additional labyrinth features for dust exclusion

Standards & Quality:

All industrial shaft seals comply with international standards such as DIN 3760 / DIN 3761, ensuring dimensional consistency and high performance in demanding conditions.
