Non-Contact Bearing Isolators: A Key to Contamination-Free Semiconductor Manufacturing

In semiconductor manufacturing, contamination is the enemy. Even a particle smaller than a micron can compromise wafer quality, reduce yield, and result in costly downtime. For critical rotating equipment—such as pumps, blowers, and motors used in fabs—bearing protection is needed to maintaining cleanroom standards. Traditional sealing methods like lip seals and labyrinth seals often fall short, either wearing out prematurely or allowing contaminants to pass through.

From Seal Failure to Production Hero: A Cryogenic Case Study

Cryogenic systems present some of the most demanding challenges in sealing technology. Whether it’s liquid nitrogen (LN2), LNG, or other cryogenic gases, temperatures plunging to -196°C or below can cause traditional elastomer seals to crack, shrink, or leak. This case study explores how a critical sealing failure in an LNG valve was transformed into a performance breakthrough—thanks to a custom-engineered PTFE spring-energized seal from Parjet.

Helical vs Canted Coil Springs in High-Vibration Environments: Which One Holds Up Best?

When equipment faces intense vibration—such as in aerospace, electric vehicles (EVs), or oil & gas applications—the choice of spring energizer becomes mission-critical. Vibrations can not only destabilize sealing pressure but also lead to premature fatigue, relaxation, or outright failure. In this article, we compare helical springs and canted coil springs under high-vibration conditions, exploring their strengths, limitations, industry applications, testing standards, and practical design guidance.

Temperature vs Pressure: The Double Challenge for PTFE Spring Seals

In the world of advanced sealing solutions, PTFE spring seals have become the go-to choice for industries requiring durability, chemical resistance, and low friction. However, one of the biggest engineering challenges lies in managing the dual demands of extreme temperatures and high pressures—two conditions that often coexist in critical applications like aerospace systems, hydraulic cylinders, semiconductor processing, and hydrogen fuel technologies.

Reshoring? Why U.S. Manufacturers Are Turning to Taiwan’s IATF 16949 Seal Suppliers

As geopolitical risks, tariff pressures, and global supply chain disruptions continue to rise, U.S. manufacturers are increasingly turning toward reshoring—bringing production closer to home or sourcing from more reliable partners. One key category in this shift is precision-engineered components like hydraulic seals, rotary seals, and mechanical seals, where quality and traceability are mission-critical.
