SD 117

Model DS 117 is a single acting collar for medium and high pressure hydraulic cylinders.
Its profile is asymmetrical, with a sealing lip on the inside, a secondary lip and a press fit on its outer diameter. It has an edge or secondary lip on the heel that prevents dirt from entering.
- Very good dynamic and static watertightness, thanks to the edge.
- The additional edge increases protection against contaminants.
- Suitable for medium and heavy mobile machinery.
It can be machined in both polyurethane and elastomers. See section on
