Inner ring and outer ring must be in a flush position.

Tolerances
| housing: | K 7 |
| shaft: | h6 |
| surface finish: | Rz = 6.3 µm |
Alternative tolerances
If your design should require looser press fit of the seal due to ease of mounting you might use the tolerance fields H7 or G7, respectively g6 or f7. When using these fits it will be necessary to take care for additional fixing of the GMN labyrinth seal to the housing or shaft by using additional glue.
The axial clearance as shown in the table of dimensions means the total axial movement of both rings from one end position to the other. If mounting the seal flushes it may allow half the axial clearance in either direction.
Please have in mind that the outer ring might be at maximum 0.1 mm wider than the inner ring.
