ROTOSTAT E

The ROTOSTAT E series consists of wear-free hydrostatically regulated radial gap seal systems with self-centring sealing bushings. This sealing principle enables reliable operation under very high pressures and at high speeds. The critical load areas in the primary and secondary sealing sections are provided with resistant coatings and finished with the best possible surface quality in order to achieve the greatest possible level of reliability.聽

ROTOSTAT E products can be used anywhere where very high pressures of up to 600 bar and high speeds are required at the same time. Typical areas of application include the supply of oil or emulsion in chucks and collets in machine tools, rotor blade pitch control in wind turbines, hydro power plants, high-speed rotary tables, steel coilers in steel mills and many more.
