Piston compact seal (KR)

It is bi-directional seal for use in light to medium duty hydraulic applications.Low friction,abrasion and extrusion resisyance.

KR is a double-acting piston sealing set for housings. It is preferably used in the pressure range up to a maximum of 300 bar. The seal components are a slide ring consisting of a newly developed polyurethane with improved sliding qualities and an especially high module and a leader element with rectangular cross-section made of an NBR elastomer.

 

The KR profile is suitable for use in all standard indus­trial cylinders as well as in farming equipment, light con­struction machinery and mobile devices. Due to the exceptionally high dynamic sealing performance, it is particularly suited for leakage-critical applications.

Also available in the new 700-version

 

Advantages

- Exceptionally high sealing performance, stati­cally as well as dynamically.

- Can also be applied for single action.

- Excellent wear resistance.

- Functional reliability at critical temperatures.

- Constantly low running friction throughout the entire operating time.

- High extrusion resistance.

- Simple snapping installation on a solid piston.

- Short axial installation length.

- Adaptability to special conditions regarding tem­perature or medium by selection of respective compounds.

- Fast sampling of any non-standard size possible.
