Faster development and increased profitability with virtual prototyping

With virtual prototyping using FEA, you can reduce many of these iterations. FEA makes it possible to optimize both geometry and material selection before anything is manufactured, resulting in a much more accurate initial design. This means fewer prototype tools, fewer rounds of testing, and a lower risk of costly detours.

Modern FEA tools make it possible to quickly evaluate complex design alternatives. You can test hundreds of scenarios and immediately see how the seal is expected to perform. This results in a smoother and more controlled development process, where decisions are made on a more reliable basis. FEA helps create seals that both perform better and cost less to develop!

The bottom line is clear: shorter development time, lower testing costs, and higher-quality solutions. This directly impacts the manufacturer’s profitability—and delivers more value to the customer.

We use the Marc Advanced Nonlinear Simulation Solution from MSC Software for this purpose.

When standard shaft seals reach their limits

Superior abrasion resistance

In many applications, wear is one of the primary causes of seal failure. Polyurethane is known for its excellent abrasion resistance and can provide significantly higher wear resistance than many standard shaft and oil seals. The result may be longer service intervals, reduced maintenance requirements, and improved operational reliability.

Retrofit into existing seal grooves

Upgrading a sealing solution does not always require extensive modifications. Polyurethane rotary lip seals can often be installed in existing seal grooves, making it possible to improve performance without major redesigns or costly equipment changes. However, operating conditions and installation geometry should always be evaluated carefully. Small details can have a significant impact on sealing performance and service life.

No metal components, no corrosion concerns

Traditional shaft seals often contain metal reinforcement elements that can become vulnerable in corrosive environments. Rotary lip seals manufactured entirely from polyurethane eliminate this concern. This makes them particularly attractive in applications exposed to moisture, aggressive media, or environments where corrosion resistance is essential.

Increased pressure resistance

Many conventional rotary shaft seals are designed for limited pressure conditions. If operating pressures exceed specs, seal performance and service life may be affected. Polyurethane rotary lip seals can offer increased pressure resistance compared to traditional sealing solutions. In applications that combine rotational movement with elevated pressure levels, this can be an important advantage.

Could polyurethane be the right choice for your application?

There is rarely a single sealing solution that fits every operating condition. Factors such as pressure, speed, temperature, media compatibility, and shaft design all influence long-term performance. If premature wear, corrosion, or pressure limitations are creating challenges in your application, it may be worth assessing whether a polyurethane rotary lip seal could provide a more suitable solution. The best sealing solution is often the one you never have to think about. The consequences of choosing the wrong one, however, are usually far more visible.

Rapid delivery of machined seals in Kalrez® 0090

The FFKM-compounds we offer, all with their unique properties, is highlighted on the below links.

FFKM has the broadest chemical resistence and highest temperature resistence of all elastomers.
In some applications FFKM is the only elastomer with a satisfactory performance and this performance has traditionally come at cost in terms of actual price, but also considering availability and lead time. In some cases, this is the real cost driver.
In addition to machined seals and components you can also benefit from molded parts in the same FFKM-compounds for a cost-effective alternative for larger series.
Using our in-house tooling and molding capacity we offer short delivery time for standard profiles and complex parts, including metal-bonding.
