Both rings of a gap seal must be in a flush position.
See also our installation.
Tolerances
| housing: | H 7 |
| shaft: | h7 |
| surface finish: | Rz <= 10 µm |
Assembly
The chamfers' length "l" of shaft and housing depends on the width "b".
l = 0.1 x b
The axial end play of seals inner and outer ring in mounted position will be roughly 0.5 to 0.8 mm (from one end position to the opposite). When mounting the seals in flush position you may use half the value in either direction.
The larger gap diameter e2 is always facing the medium to be sealed.
When using the "Sa" and "Si" type, care should be taken that the drain notch in the stationary part is always located at the lowest point.
Please note also our indications of the mating parts!
Mating parts
For optimum sealing efficiency of a GMN gap seal the maximum or minimum connecting diameter should not be exceeded.
