Function

The KNA 28 u-ring is a single-acting piston seal with an asymmetrical design. Due to the synergy of geometry and material, it is particularly well-suited for extreme loads.

Installation

The KNA 28 can be installed in cut grooves starting from an inner diameter of 25 mm with the use of suitable installation tools. With smaller diameters or larger profile widths, we recommend axially accessible installation housings.

Remarks

Seals made of TPU are very robust and are particularly well-suited for applications in mobile hydraulics, particularly earth moving equipment.
