FDI® - shaft seal
In case of large radial runout FDI®-Seal model Y or YS is recommended.
The seal will rotate with the shaft. The dynamic movement/contact will be at the top axial lip sections, which are in contact with the housing (or cover plates).
Axial movement of the shaft is allowed at the same time.
For large axial movement model Y-G or Y-SG is recommended.
FDI®-Y Seal are designed for pressure load as well. The radial runout is limited acc. indicated gap C between shaft and housing. For larger runout special seals are available on request

spring: stainless steel

media to be sealed: oil, grease, water, slurry, suspension with hard particles

The data shown above is based on long lasting experience in the manufacturing and use of sealing elements. As there are many unknown possible parameters and conditions in practice, which may limit standard performance, it is requested that the user runs practical tests. Except as expressly stated, Friedrich‘s liability, expressed or implied, is limited to the published selling price of our defective item.
