Commercial Description

Stepseal® V is based on the dynamic, unidirectional Stepseal® sealing concept. During the extending stroke of the rod, focusing of contact force on the unique Stepseal® sealing edge creates high local sealing pressure and limits the micro fluid film formation under the seal. When the rod is retracted, the design of the full Stepseal® sealing face supports hydrodynamic back-pumping of the fluid film, and so ensures leak-free sealing efficiency with low friction and long service life.

Installation & Handling

In long-stroke cylinders, and equipment operating with low speed during retraction, it has been found that hydrodynamic back-pumping may become insufficient to prevent build-up of pressure in the seal system behind the primary seal. Pressure build-up in the seal system leads to leakage, increased friction and wear, and may ultimately require replacement of the seals. The usual precaution in such equipment has been to provide space for a buffer volume behind the primary seal, or to install a drain line. The built-in check valve function is used to eliminate pressure build-up and so render buffer volumes and drain lines obsolete. Extensive development has now brought the inherent prevention of pressure build-up together with dependable sealing performance in one element; Turcon® Stepseal® V. Stepseal® V has the efficient seal performance and outstanding service life of the Stepseal® range, and the reliable prevention of pressure build-up brought by a refined check valve function.

Material Properties

  • Pressure : Up to 50 MPa (Turcon® M12)
  • Speed : Up to 15 m/s with reciprocating movements, frequency up to 15 Hz
  • Temperature : -30 °C to +200 °C (depending on seal and O-Ring material)
  • Media : Mineral oil based hydraulic fluids, flame retardant hydraulic fluids, environmentally safe hydraulic fluids (plant based oils), phosphate ester and others, depending on the seal and O-Ring material
  • Clearance : The maximum permissible radial clearance Smax. is shown in the table on the next page as a function of the operating pressure and functional diameter.

Seal Capabilities

  • Same basic function as Turcon® Stepseal® 2K
  • Check valve function of O-Ring eliminates risk of fluid bypassing the seal during pressure loading when pressurized
  • No system pressure on secondary sealing element and/ or Excluder®
  • Independent of any speed relation of counter surface
  • Independent of stroke length and deflection
  • Minimum contribution of friction of secondary sealing element and/or Excluder®
  • Minimum wear of secondary sealing element and/or Excluder®
  • Increased leakage control
  • Prolonged seal life Increased operational reliability
  • Fits standard Turcon® Stepseal® 2K groove dimensions as well as ISO 7425 seal housings
