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.

General Test Capabilities:

  • Seal Diameters: up to 60 cm (24 inches)
  • Shaft Speeds: up to 70,000 rpm
  • Oil Pressures: up to 30,000 KPa (4,000 psi)
  • Gas Pressures: up to 20,000 KPa (3,000 psi)
  • Temperatures: up to 815° C (1,500°F)
