Rotary Seals

Rotary seals keep lubrication in and contaminants out.

In the intricate world of machinery where rotational movements are crucial, rotary seals emerge as the unsung heroes. These specialized seals are meticulously designed to handle the challenges of sealing rotating shafts and rods, ensuring optimal performance across diverse applications.

From safeguarding automotive engines to ensuring the seamless operation of industrial turbines, rotary seals are fundamental in preventing lubricant leakage and keeping out contaminants. Today, their importance spans across various sectors, making them a cornerstone in modern mechanical design.

Why Use a Rotary Seal?

Rotary seals play a pivotal role in many industrial settings and machinery where rotational movement is a key operation. They ensure optimal performance by offering unique sealing solutions for dynamic applications. Key reasons include:

Sealing Rotating Components

Designed for sealing rotating shafts or rods, ensuring containment of lubricants and prevention of contaminants.

Compensating for Dynamic Movement 

Accommodating the challenges of dynamic motion to maintain a tight and effective seal.

Temperature and Speed Resistance

Handling varying temperatures and high rotational speeds with specialized materials.

Preventing Lubricant Leakage

Retaining lubricants to ensure smooth machinery operation and minimize friction-based breakdowns.

Protection Against External Contaminants

Shielding machinery from contaminants like dirt, dust, and water.

Enhancing Equipment Lifespan

Prolonging the lifespan of machinery by ensuring optimal sealing and preventing premature wear.


Where machinery spins,

our rotary seals ensure it spins smoothly.

Common Types

Metal-Cased Rotary Seals

These seals may feature an additional rubber jacket to enhance sealing on the external diameter.

Nonmetallic Cased Seals

Often crafted from polymers or thermoplastics, are renowned for their flexible yet resilient outer casings that excel in various conditions.

Case-Free Seals

Designs like the V-seal prioritize efficiency without an outer case.

PTFE Lip Seals

Renowned for low friction and broad temperature tolerance, they excel in environments demanding chemical compatibility and high-speed operation.

Metallic vs. Nonmetallic Cases

Metal cases, often constructed from steel or stainless steel, are lauded for their durability and strength, making them suitable for heavy-duty applications. On the other hand, polymer or thermoplastic cases offer a blend of flexibility and resilience, adapting well to various conditions and offering excellent resistance to potential corrosives. The choice between metal and nonmetallic cases largely depends on the application's specific requirements, balancing factors like environmental conditions, operational pressures, and potential chemical exposures.
