Isomag bearing isolators stop water and condensate from contaminating your turbine oil. Isomag bearing seals utilize proven lapped flat face sealing technology putting an end to leaky labyrinths, and eliminating the need to drain water from your turbine oil. The Worthington 4S steam turbine is a machine that readily accepts our bearing seal upgrade. The Isomag bearing isolators replace the OEM labyrinth seals with little or no modification required. The Isomag bearing seals are mounted inside the bearing housing so as to place them away from the heat source and directly in the lubricating oil. We also recommend using a shaft mounted steam deflector with the inboard seals. This will further reduce the operating temperature at the seals and bearings.
Isomag bearing isolators are designed to last for years and never damage your turbine shaft. To insure a quality fit, Isomag seals are best installed during a complete turbine overhaul.
