Wiper Seals

Wipers are designed to keep dust, dirt, sand and others off the rod and the sealing and guiding elements, avoiding abrasive damage caused by external contamination.

Features

  • The profile is designed with interference on the OD which provides a good static fit in the groove, preventing the entry of humidity and other contamination via the outside diameter.
  • Sharp wiping lip to ensure any dirt is wiped off properly.
  • For housings to ISO 6195-Type A.
  • Pressure from the trailing side has to be avoided.

Application

Reciprocation rods in hydraulic cylinders, plungers. Max. pressure 0 bar, max. speed 2 m/s.

Installation

Snap-in installation.

When the cylinder cannot be dismantled, the wiper can also be installed in cut version. In this case the diameter should be increased by 2-3%.

  • The profile is designed with interference on the OD which provides a good static fit, preventing the entry of humidity and other contamination via the outside diameter.
  • The design of the wiper lip supports the re-circulation of the remaining oil film into the cylinder, whilst the exclusion of contamination is guarantee

Application

Reciprocation rods in hydraulic cylinders, plungers. Max. pressure 0 bar, max. speed 4 m/s.

Installation

Snap-in installation.

  • The design of the wiper lip supports the re-circulation of the remaining oil film into the cylinder, whilst the exclusion of contamination is guarantee
  • The sealing lip on the fluid side reduces the remaining oil film to a minimum if used in combination with composite seals as a tandem seal.
  • For housings to ISO 6195-Type C.

Application

Reciprocation rods in hydraulic cylinders, plungers.

Can also be used as rod seal/wiper combination in pneumatic applications.

Installation

Snap-in installation.

When the cylinder cannot be dismantled, the wiper can also be installed in cut version. In this case the diameter should be increased by 2-3%.

Features

  • The profile is designed with one sharp lip for wiping off any dirt on the rod
  • The residual oil film is recovered
  • The wiper consists of a PTFE wiping part and an O-Ring as preload element, maintaining contact pressure on the rod
  • Due to the use of an O-Ring the wiper is able to compensate deflections of the r
  • Good dry running properties.
  • No “stick-slip”.
  • Pressure on the trailing side should be avoided.
  • For housings to ISO 6195 Type D.

Application

Reciprocation rods in hydraulic cylinders, swiveling and coiling rods, plungers.

Installation

Snap-in installation for wipers bigger 25mm otherwise a partite groove is recommended. A large insertion chamber needs to be provided (angle 20-30°).

Features

  • Symmetrical, single acting piston/rod seal, combined with pressure ring and support ring.
  • By adjusting the number of packings friction and leakage characteristics can be influenced.
  • Excellent static and dynamic sealing performance.
  • Excellent performance in high pressure conditions.
  • Useable for short and long stroke lengths.
  • High wear resistance.

Application

Reciprocating pistons/rods in hydraulic cylinders, plungers etc.

Used in heavy duty applications (presses) with return stroke by equipment weight. Max. pressure 500 bar, max. speed 0.5 m/s.

Installation

Installation normally in open housings.

At closed housings the parts need to be split. In this case the seal must be done  slightly larger (approx. 1% in diameter)
