Dynamic Sealing

Produced using highly efficient production methods, maximising the cost-effective use of superalloys.

Our dynamic sealing range includes special low cost rings for axially sliding applications.

Dynamic seals are a critical part of Variable Geometry Turbos (VGTs) which combine the benefits of both large and small turbos by widening the response range of one turbo to get the boost range needed. This is achieved by a swinging set of radial vanes that are adjusted by an axially sliding mechanism to vary the air flow through the turbo in correlation to engine speed. Our dynamic sealing rings create an effective seal against the axially moving components and provide the backpressure needed for the mechanism to function. 

Our proprietary forging process produces dynamic sealing rings of the highest quality, whilst minimising waste and optimising use of the high value exotic and temperature-resistant alloys needed to withstand the very high temperatures of exhaust gases.

Another great benefit of our forging process is that it can easily be adapted to accommodate any special shapes and ring profiles that you may require.

  • Wide range of diameters for both car and commercial vehicle applications.

  • Suitable for high temperature applications in the gas path.

  • Special profile sections available to suit retaining ring features.

  • Highly efficient production methods, maximising the cost-effective use of superalloys.

We have been assisting customers with VGT designs since they were first introduced into mainstream production and now with several different VGT actuation systems using our products, we are the preferred choice of OEM turbo makers, as we can fully support with design, function and volume production to support the demand.
