High Speed Rotary Shaft Seals
If you’re running machinery at high speeds, you already know that not all rotary shaft seals are created equal. At PSI, we design high speed rotary shaft seals to take on the challenges that come with faster rotations, more heat, and the extra wear those conditions bring. We’ve got decades of experience helping customers like you improve machinery uptime and keep leaks and contamination at bay, no matter how tough the environment gets.
What Makes a Seal “High Speed”?
Think of high speed rotary shaft seals as the next step up from your standard options. They’re built using advanced materials and precise engineering, especially for applications where conventional seals can’t keep up. Our high speed designs feature low-friction lips, optimized spring energizers, and durable materials that stand up to increased centrifugal force and heat. The result? Less wear, fewer breakdowns, and reliable sealing month after month.
Where You’ll Find Our High Speed Shaft Seals
Our customers rely on these seals in a wide range of industries and applications, including:
- Electric motors and generators
- High speed pumps, compressors, and blowers
- Centrifuges and turbomachinery
- Machine tool spindles and other industrial equipment
- Automotive and aerospace systems
- Wind turbines and power generation
- Food, pharma, and processing lines
We know that every industry has its unique set of challenges, and we’re ready to help you find the right solution for yours.
Designed For Demanding Conditions
At PSI, we only use trusted, field-proven materials like PTFE, FKM (Viton®), nitrile, and specialty elastomers. Each is chosen for its ability to handle high speeds, harsh chemicals, or tough temperature cycles. We also offer seals with metal cases and spring-energized lips for applications that push the boundaries of speed and pressure.
Every part of our high speed rotary seal is designed with performance in mind:
- Low-friction lips minimize heat and energy loss during high RPM operation
- Precision-fit designs help prevent leaks, even at elevated temperatures or with shaft misalignment
- Specialty lips and secondary barriers keep out dust and contaminants
- Robust materials mean longer life and fewer surprises
