Sealing systems and guiding elements

Sealing systems

We'll find the best sealing system for you. With low stick-slip contact sealing elements, or contact- and wear-free. We seal everything:

  • pressures of up to 2.000 bar
  • temperatures from -40 °C to 200 °C
  • fluids between moving or static parts
  • mineral oils, synthetic, bio-degradable, and any other liquids
Guiding elements

Strong and accurate bearings are essential for a long service life and for the correct functioning of a machine. We design accurate plain and hydrostatic bearing. For all types of sliding surfaces:

  • cast iron or non-ferrous metal
  • with a bronze or synthetic layer, inseparably connected to the component part
  • with wear rings or bearing bushings

Typical for Hänchen: We're at home with sealing and guidance technology.

From conventional sealing technology to hydrostatic bearings – we're happy to provide advice and assistance. Component part diameters from 12 mm to 200 mm.

Example 1: Plain bearing flange

Flanges are fixed to the machine with screws to absorb forces from rods or shafts.

We develop bearing flanges with exact guiding systems as plain bearing, for example with our special Servoslide® synthetic coating. As an integral, inseparably applied part of the cover, this coating is suitable for operating temperatures of up to 80 °C. The slide surfaces of the synthetic guide act as vibration-dampers, prevent edge pressure and guarantee largely stickslip-free movement.

Example 2: Sealing and guide bushing

Sealing and guide bushings are used in machines where rods or shafts are led out of a pressure chamber.

Appropriate seals can withstand pressures of 300 bar and more, and keep a wide variety of liquids inside the machine space.

To give the rod or shaft a perfect bearing seat, we use plain bearings made of steel with high-precision bronze guides. These make it possible to realize rod or shaft feed throughs for temperatures of up to 200 °C.

Example 3: Hydrostatic bearing

A hydrostatic bearing is a no-contact guiding system with the rod or shaft "floating" on an oil film. This method allows creating linear or rotary bearings that feature extremely low friction forces while at the same time being able to bear very high bending loads.

The pressure for the bearing pockets of the hydrostatic bearing is supplied through active pressurization of the bearing pockets on the perimeter.

The corresponding rod or shaft will be adapted for your requirements.
