AYR
The double wiper ring profile AYR is designed to prevent contamination ingress while the piston rod is moving. This is guaranteed by its special design with a sharp contrasted wiper edge and an additional seal lip at the medium site.
The latter ensures the return of the rest film of oil into the system. Thereby, it prevents the development of scratches at the running surface and extends the working life of the seals.
The oversized diameter ensures the close fit in the groove and the form fit at the outside diameter of the wiper ring.
No specific action e.g. ring nuts and retaining plates or special fits are necessary for the installation. The possible corrosion of wipers in conjunction with a metall cage between cage and cylinder head is prevented. 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, (Hydraulik), NBR approx. 90 Shore A (Pneumatik).
The HPU compound is characterized by both good ozone resp. weather resistance and a high abrasion resistance.
| Working temperature: | - 40 °C to + 110 °C > FKM to + 200 °C < |
| Surface speed: | ≤ 2 m/s |
MOUNTING INSTRUCTIONS
The wiper ring profile AYR is easy to mount by kidney-shaped deformation.
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.
