Product Description
1. The Ultrathanpiston sealing set profile KR complements the product range of double-acting piston seals (OE, OK) for installation housings according to ls0 7425/t by a product which 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-elastomere.
2. Range of application
The KR profile is suitable for use in all standard industrial cylinders as well as in farm ing equipment, light construction machinery and mobile devices. Due to the excep tionally high dynamic sealing performance, it is particularly suited for leakage-critical applications.
Operating pressure ≤300 bar
Operating temperature -35°ºCto +110ºC
Sliding speed ≤0.5 m/s
3.Compounds
Slide ring: Ultrathan P5062, modified polyurethane with a hardness of approximately55 Shore D.
Expander ring: NB078, NBR-elastomer with a hardness of approximately 80 Shore A. Installation
The installation groove must be carefully deburred and cleaned. The cylinder bore must have a leading edge chamfer. Profile KR can be snapped into closed grooves.
in case of special operating conditions (specific pressure loads, temperature, speed, use in water, HFA. HFB fluids etc.), please contact our consultancy service for a selection of the material and design best suit- ing your particular application requirements.
