Pressing into the housing
We recommend pressing into the bore with the aid of mechanical, pneumatic or hydraulic insertion equipment and an assembly press (→ Fig. 8).
The axis for the assembly press is the axis of the bore. An inclined position is not permitted (→ Fig. 10).
A metal face (assembly press housing) must be present (→ Fig. 8, → Fig. 9). If this is not possible, a metal face must be provided on the underside of the fitting equipment.
The press-in force, particularly when installing from
the back side, must be applied as near as possible to the outside diameter of the seal. The diameter of the assembly press must be chosen to suit (→ Fig. 8, → Fig. 9). If necessary, please inquire.
If the diameter of the assembly press is too small, there is a risk that the seal will bend (→ Fig. 11).
A mounting plate must be used for hammer assembly (common with large seals) (→ Fig. 12). In case of
an excessively high load on a specific point during installation, there is a risk that the seal will be bent (→ Fig. 10).
