Dynamic Test Laboratory

Extreme Testing Seals and Sealing Systems

In Stein’s test lab, we can accurately simulate the extreme limits of operating conditions, which allows us to accurately predict and verify performance under the most rigorous operating conditions.

Each of our over 20 dynamic test rigs, including 2 inter-shaft rigs, is custom designed to meet Stein’s high standards and each can be reconfigured quickly for multiple programs to provide fast, concurrent and cost-efficient testing for our customers.

Our testing expertise and equipment are also available to our customers so that they may validate their own designs, or test non-seal related components or systems.

Dynamic Attitude Test Rig

Stein Seal^® Company developed dynamic test rig capable of simulating extreme engine attitudes at any angle ranging from horizontal up to 90⁰ vertical in order to verify seal performance. In addition to matching gas turbine engine bearing sump pressures and temperatures, the rig shaft rotates at speeds up to 20,000 rpm and can be maintained during the entire tilting process.

Aerospace Seals and Sealing Systems

Stein has developed an in-depth understanding of the extreme operating conditions to which seals used in the main shaft bearing sumps, gearboxes and generators in aircraft engines are subjected. Each precision sealing system is custom designed to perform flawlessly with low wear and long life. Our seals will withstand the wide range of conditions that will occur during normal operations including temperature extremes, high speeds and strong vibration.
