AFR
The wiper ring profile AFR is designed to prevent contamination ingress while the piston rod is moving. This is guaranteed by its special design. Thereby, it prevents the development of scratches at the running surface and extends the working life of the seals.
The oversized outside diameter ensures the form fit between the housing bore and the metal sheath of the wiper.
By its design, the wiper lip closes flush with the housing and is so safe from mechanic damage as far as possible.
No specific action e.g. ring nuts and retaining plates or special fits are necessary for the installation.
By the special hydrolysis-resistant polyurethane compound, high stiffness and outstanding abrasion resistance are combined. Intermediate sizes or inch dimensions can be produced short-dated, if required.
APPLICATION RANGE
Designed for axially moved rods at hydraulic and pneumatic piston rods.
MATERIAL
Standard compound: hydrolysis-resistant polyurethane with a hardness of approx. 93 Shore A. This compound is characterized by both good ozone resp. weather resistance and a high abrasion resistance.
| Working temperature: | - 35 °C to + 110 °C |
| Surface speed: | ≤ 2 m/s |
MOUNTING INSTRUCTIONS
The wiper ring profile AFR has a oversized outside diameter, so that a press fit arises at the interaction with the housing bore DH8. To avoid damages at the wiper lip, it should not to be pulled over sharp edges.
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.
