| Method of Operation
The sealing effect of the U-Cup comes from the intrinsic preload of the seal body and from the compression of the seal lips during installation.
In operating condition, the radial mechanical contact forces are superimposed by the system pressure. At low stroke speeds, U-Cups can tend to have a stick-slip
effect due to an inadequate lubrication film formation in the seal clearance and to their material properties. This behaviour corresponds to the Stribeck curve described in the relevant literature.
Advantages
1) Good sealing effect at high and low pressures
2)Good abrasion resistance, wear-resistant
3)Unaffected by sudden loads
4)Suitable for small grooves
5) Simple installation.
