TURCON STEPSEAL 2K

Description

Rod seals must exhibit no dynamic leakage to the atmosphere side under all operating conditions and must be statically completely leak tight when the machine is at a standstill. Furthermore, they should achieve a high degree of mechanical efficiency through low friction and be easy to install in small grooves. Costs and service life must meet the high expectations of the operator.

The rod seal Turcon Stepseal 2K comes closest to satisfying these ideal demands. Since the first Stepseal was patented and introduced to the market in 1972, Busak+Shamban has maintained the series as technically outstanding seal elements through continuous innovative further development of the design and of the TurconR and Zurcon materials. Turcon Stepseal 2K continues the tradition for improvement.

With the introduction of StepsealR it was possible for the first time to arrange several seals, one behind the other, thus allowing statically and dynamically tight

double-acting tandem seal configurations to be created, without any disturbing build-up of intermediate pressure. The single-acting seal element is made of high-grade Turcon or Zurcon materials with outstanding sliding and wear resistance properties. It is installed according to ISO 7425/2 and Busak+Shamban standard grooves, using an O-Ring as energizing element.

Method of operation The sealing performance of Turcon Stepseal 2K results from the hydrodynamic properties of the seal. The classic Stepseal seal edge creates a steep contact pressure gradient on the high pressure side and a shallow contact pressure gradient on the low pressure side. The controlled pressure gradients minimizes fluid adherence to the piston rod during the extending stroke, and enables residual fluid film on the rod to be returned into the system on the return stroke. This is united with new patented and patent applied design features which further improve the performance of Stepseal 2K under severe service conditions.

The O-Ring relief chamfer reduces pressure loading on the seal, whereby contact with the rod is optimised and sealing performance is improved at high service pressures. The special high-lift rear chamfer combines a smooth downstream sealing face with the ability to meet large radial clearances and hardware tolerances. Turcon Stepseal 2K gives high static and dynamic sealing performance, and the build-up of intermediate pressure often found with tandem seal configurations (see Figure 16) is efficiently suppressed.

Advantages

– High static and dynamic sealing effect
– High extrusion resistance, meets high hardware clearances
– Low friction, high efficiency
– Stick-slip free starting, no sticking
– High abrasion resistance, high operational reliability
– 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 2.600 mm rod dia.

Technical data

Operating pressure: up to 80 MPa
Speed: up to 15 m/s with reciprocating movements, frequency up to 5 Hz
Temperature: -45°C to +200°C (depending on O-Ring material)
Media: Mineral oil-based hydraulic fluids, flame retardant hydraulic fluids, environmentally safe hydraulic fluids (bio-oils), water and others, depending on the O-Ring material (see Table X)
Clearance: The maximum permissible radial clearance Smax is shown in Table XI, 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.

Materials

The following material combination has proven effective for applications with hydraulic oils containing zinc:

Turcon Stepseal 2K: Turcon T46
O-Ring: NBR, 70 Shore A N
FKM, 70 Shore A V
Set code: T46N/T46V For specific applications, other material combinations as listed in Table X, may also be used.

Series

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

Table XI, 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.

Application Examples

  • Mobile hydraulic
  • Standard cylinders
  • Machine tools
  • Injection moulding machines
  • Presses
  • Automobile industry
  • Hydraulic hammers
  • Servo hydraulics

Redundant Sealing System

In many applications, secondary seal systems are demanded. Figure 16 shows such a tandem configuration with the StepsealR 2K.

Turcon Stepseal 2K figuur 16

In this configuration it must be noted that a sufficiently large space is formed between the seals to take the hydraulic fluid, as shown in the figure.

Depending on the application and the operating conditions, the combination of different materials offers a further improvement in the sealing efficiency and the service life of the system, e.g. in hydraulic cylinders subject to high loads and under rough operating conditions, the primary seal should be made of Turcon and the secondary seal of Zurcon.

Stepseal 2K elements should always be used in combination with a double-acting scraper to provide an optimum sealing effect.

The scraper Turcon Excluder 2, Turcon Excluder 5, Zurcon Excluder 500, DA17, DA22 and DA24 are well suited to such applications. For further details, please refer to our ”Scrapers” catalogue.
