Rod Seals

The rod seal profile C1 complies with the requirements of manufacturers of hydraulic and pneumatic devices for seals that require the smallest possible installation space. Outstanding sealing properties are achieved with the smallest possible profile width and height.

Extremely low friction thanks to minimal contact with sealing surface. Support rings or brackets are not required due to the special design. It can also be used in pneumatic devices with lubricated compressed air. We would be happy to provide custom installation advice upon request.

For installation in oil-free pneumatic systems (dry air), we recommend our profile E5, which fits into the same installation space.

The Ultrathan® rod seal HL is a friction-optimized sealing solution for mobile and stationary hydraulics with an all-new functional principle: The single-acting rod seal possesses pressure-active, cascading dynamic sealing edges. The effect: Significantly reduced static and sliding friction in hydraulic cylinders, as well as the increased effectiveness of hydraulic systems.

Specification

  • Profile description :
    HL
  • Operating pressure max :
    250
  • Sliding speed max (m/s) :
    1.0
  • Temperature(°C) :
    -35/+110

The rod seal profile R3 is a sealing element with a compact design and a special anti-extrusion ring.

This combination is characterized by its freedom of movement, exceptional sealing properties and high wear resistance, even under extreme operating conditions.

Even under low-pressure conditions or with rods that move without pressure, they guarantee a leak-free seal.

Specification

  • Profile description :
    R3
  • Operating pressure max :
    315
  • Sliding speed max (m/s) :
    0.5
  • Temperature(°C) :
    -30/+100

The Ultrathan® rod seal profile B3 is a lipped ring with a tight fit along its external diameter. This seal is used when the physical characteristics of normal or fabric-reinforced elastomers are no longer sufficient.

Specification

  • Profile description :
    B3
  • Operating pressure max :
    400
  • Sliding speed max (m/s) :
    0.5
  • Temperature(°C) :
    -35/+110

The Ultrathan® rod seal profile BS is a lipped ring with a tight fit along its external diameter and a secondary sealing lip. Thanks to this additional lip, a generous lubricating film is provided under the seal. This prevents dry running and increased wear to a great extent, thereby allowing for a longer service life. In the past, under certain operating conditions, a passable seal could only be achieved with two consecutively placed seals. In many cases, this expensive tandem placement can be replaced with the rod seal BS.

For telescopic cylinders, we recommend the version with a 4 mm profile width.

Specification

  • Profile description :
    BS
  • Operating pressure max :
    400
  • Sliding speed max (m/s) :
    0.5
  • Temperature(°C) :
    -35/+110

The single-acting rod seal kit profile OD consists of a PTFE rod sealing ring and an elastomer O-ring as a preloading element. The asymmetric cross-section of the sealing ring has been designed for the optimal circulation of trailing lubricant during the stroke in both directions. An optimal seal is achieved by installing it in a tandem arrangement in combination with a double scraper ring.

Profile OD is particularly suited to piston rods in master cylinders, server-driven systems, machine tools and rapid closure cylinders. The seal kit has also been implemented successfully in the automobile industry (e.g. in shock absorbers) and the process manufacturing industry.

Specification

  • Profile description :
    OD
  • Operating pressure max :
    600
  • Sliding speed max (m/s) :
    4.0
  • Temperature(°C) :
    -30/+100

The Ultrathan® rod seal profile BD is a subsequent development of the Parker seal Park-O-Pak®, with a secondary sealing lip and a highly extrusion-resistant support ring. Thanks to this additional lip, a generous lubricating film is provided in the sealing gap. This prevents dry running and increased wear to a great extent, thereby allowing for a longer service life. Furthermore, in certain cases this second sealing lip can replace a cost-intensive tandem arrangement, in which under certain conditions a passable seal could only be achieved with the use of two consecutively placed seals in separate installation spaces.

This seal is used when the physical characteristics of normal or fabric-reinforced elastomers are no longer sufficient.

Specification

  • Profile description :
    BD
  • Operating pressure max :
    500
  • Sliding speed max (m/s) :
    0.5
  • Temperature(°C) :
    -35/+110

The double-acting piston seal set profile ZW consists of an elastomer seal, two anti-extrusion and two angular guide rings.

Specification

  • Profile description :
    BU
  • Operating pressure max :
    500
  • Sliding speed max (m/s) :
