TURCON STEPSEAL 2K

Description

The Turcon stepseal 2k is a single-acting seal element consisting of a seal ring of high-grade Turcon or Zurcon materials and an O-Ring as energizing element. The Stepseal 2K was originally developed and patented by Busak+Shamban as a rod seal. Due to its outstanding properties, however, it is equally well suited as a single-acting piston seal where high demands are made on positional accuracy and free movement.

Advantages

– High static and dynamic sealing effect

– Stick-slip free operation for precise control

– High abrasion resistance and high resistance to
extrusion

– Long service life

– Simple groove design, one-piece piston possible

– Wide range of application temperatures and high
resistance to chemicals, depending on the choice of
O-Ring material

– Simple installation without seal edge deformation

– Available for all diameters up to 2.700 mm

– Low friction

Application Examples

The Turcon Stepseal 2K is the recommended sealing element for single acting pistons in hydraulic components for:

  • Injection moulding machines
  • Machine tools
  • Presses

It is particularly recommended in floating piston accumulators as primary seal on the oil side in combination with AQ-Seal and AQ-Seal 5.

 

Technical Data

Operating conditions

pressure:                      Up to 80 MPa

Speed:                           Up to 15 m/s, frequency up to 5 Hz

Temperature:               -45qC to +200qC *)

Media:              Mineral oil-based hydraulic fluids, flame retardant hydraulic fluids, environmentally safe hydraulic fluids (bio-oils), water, air and others, depending on the O-Ring material

Clearance:        The maximum permissible radial clearance Smax is shown in Table, as a function of the operating pressure and functional diameter.

Important Note:

The above data are maximum values and cannot be used at the same time. e.g. the maximum operating speed depends on material type, pressure, temperature and gap value. Temperature range also dependent on medium. In the case of unpressurized applications in temperatures below 0°C please contact our application engineers for assistance

Materials

Standard Application:

For hydraulic components in mineral oils containing zinc or medium with good lubricating performance.

Turcon Seal: Turcon T46

Energiser: O-Ring NBR 70 Shore A or FKM 70
Shore A depending on the temperature

Set reference: T46 N or T46 V

Special Application:

Non-lubricating fluids or pneumatic applications require self-lubricating sealing materials. Therefore we recommend:

  • Turcon Seal: Turcon T29
  • Energiser: O-Ring NBR 70 Shore A or FKM 70 Shore A depending on the temperature
  • Set reference: T29 N or T29 V
  • Rough mating surface finish and improved leakage control
  • Zurcon Seal: Zurcon Z51
  • Energiser: O-Ring NBR 70 Shore A
  • Set reference: Z51 N

Series

Different cross-section sizes are recommended as a function of the seal diameters. These are the criteria for these recommendations.

The table , shows the relationship between the series number according to the seal diameter range and the different application class sizes. These application classes are:

Standard application:    General applications in which no exceptional operating conditions exist.

Light application:    Applications with demands for reduced friction or for smaller grooves.

Heavy-duty application:   For exceptional operating loads such as high pressures, pressure peaks, etc.

Stepseal 2K are also available on request for the groove sizes to ISO 7425/1.
