Applications - Stein Seal Company

The opportunity to design solutions for an increasingly diverse base of applications in all types of industries has given us an advantage not available from other companies. So, whether you are dealing with materials such as carbon, titanium, or alloy steels with their unique properties, or rotating speeds, high pressures, extreme temperatures, and tolerances within millionths of an inch, Stein Seal has both the experience and expertise for the job.

Here are just some of the industries within which we commonly do work:

Aerospace - 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.

Industrial - Whether it be in a centrifuge, compressor or pump, Stein’s seals effectively prevent the leakage of hazardous gases and liquids under low differential pressure from escaping into the environment. These seals must operate at high temperatures and high speeds with low wear in environments that are corrosive, volatile or flammable.

Marine - We have a long history of proven reliability in marine applications, including steam and gas turbines, gearboxes and main propeller shafts. Whether the requirements are for a split ring circumferential seal that can be installed or serviced without disturbing other parts of the equipment or for any of the face, bellows or bushings seals we manufacture, Stein's products can withstand the harsh conditions of marine environments.

Nuclear - Stein products are especially effective in meeting the critical requirements for reliability and safety needed in the nuclear industry. Our extensive experience with issues such as the effects of radiation, decontamination and vibration or misalignment on seal performance and life ensures that seals operate well within regulatory and technical parameters.

Power Generation - To meet the high demands of the power industry, Stein has designed seals that virtually eliminate leakage and shaft rub damage. This has resulted in significant increases in operating efficiency while reducing expensive and time-consuming maintenance requirements.

Process Control - Maintaining the integrity of the seal while the equipment is constantly adjusted to allow for different flow speeds, is another specialty of Stein Seal. These seals must operate at both high temperatures and speeds, but with low wear in environments that are quite often corrosive, volatile or flammable.
