Technical Seals: O-Ring and Simmering Seals

What Are Technical Seals?

Technical seals play a crucial role in protecting machinery and their components. They prevent the leakage of lubricating media (oil, grease), as well as hydraulic fluids.

What Factors Negatively Affect Machine Components?

Below are the main factors that negatively impact machines and their components:

• Extreme temperature

• High humidity

• Contact with chemicals

• Contaminated environment

Seals are used across many industries. They prevent dust and other contaminants from entering the machine or its components. The sealing properties of O-rings and simmering seals help prevent leaks and contamination of lubricating fluids, which could lose their effectiveness due to dirt. Contaminants can damage working parts (e.g., in bearings), cause faster wear and tear on components, and lead to failures.

O-Ring Seals

O-rings are one of the most versatile sealing elements used in static, dynamic, hydraulic, and pneumatic parts. They are used to prevent the leakage of liquids or gases and protect against environmental contaminants like dirt, moisture, and dust. O-rings are made from various elastomeric materials such as NBR, Viton, FFKM, FPM, VMQ, EPDM, and HNBR. The choice of material depends on the environment in which the seal will be used.

Power Rubber offers durable and reliable O-rings to meet your specific needs.

Simmering Seals

Simmering seals (also known as radial lip seals or Simmer rings) are widely used in machines where rotational motion is involved. They protect machine elements from contamination (dirt, dust, mud) and moisture, and prevent the leakage of lubricating media, increasing the lifespan of individual components.

Simmering seals are made of rubber and a metal insert, which may be reinforced with a metal shield. These seals come in various types (e.g., Type A, AO, B), with key components including:

• A metal reinforcing insert

• A rubber or metal external cover

• A sealing lip with or without a spring

• Some simmering seals have an additional dust lip

These seals are ideal for use in machines such as hydraulic systems, pumps, engines, and industrial gearboxes.

O-Ring vs. Simmering Seals – Seals for Multiple Applications

Simmering seals are commonly used in drive systems, construction and agricultural machinery, mixers, robotics, and anywhere a seal between rotating and static elements is needed. O-rings are used in industries such as food processing, medical, automotive, aviation, and petrochemical industries. They are excellent for sealing applications such as brake systems, analytical equipment, and offshore drilling rigs.
