3.04
The wiper ring profile 3.04 is designed to prevent contamination ingress while the piston rod is moving. Thereby, it prevents the development of scratches at the running surface and extends the working life of the seals. Conditional on the production, this profile is available short-dated up to sizes of 3000 mm. No specific action e.g. ring nuts and retaining plates or special fits are necessary for the installation. Intermediate sizes or inch dimensions can be produced short-dated, if required.
ADVANTAGES ARE
- resistant against almost every media
- no adhesion with the surface to be stripped, very good dry operating attributes
- less loss due to the friction, supports a calm and regular movement
- owns excellent scrap attributes to highly viscous, sticky and polluted media
- applicable in a very broadly temperature area
- easy to interchange
APPLICATION RANGE
Designed for axially moved rods at hydraulic and pneumatic piston rods. Due to the excellent slide attributes of the dynamic PTFE ring, it is suitable especially well for short strokes with high frequencies and high surface speeds. The low abrasion guarantees a long service life.
MATERIAL | |
standard compound wiper ring: | PT003 |
standard compound O-ring: | NB674, NBR elastomer, 70° Shore A |
working temperature: | – 40 to + 200 °C (depending on the O-ring) |
surface speed: | ≤ 15 m/s |
MOUNTING INSTRUCTIONS
If no other security for the tight fit is possible, the assembly with an O-ring at the outter diameter is recommended. In exceptional cases, the wiper can be delivered parted.
For special cases of application (high temperatures, speed, specific pressure, use in water, HFA-, HFB-fluids etc.) please get in contact with our consultancy service.
