Cassette sealings
A cassette sealing is a fully enclosed seal with an integrated sealing system. Both
sides of the cassette sealing are static with metal inserts.

Note Action
Check the sealing to ensure that:
• The sealing is of the correct type.
• There is no damage on the sealing.
1
Inspect the mating surfaces on the manipulator before
mounting. If scratches or damage are found, the part
must be replaced since it may result in future leakage.
Do not try to grind or polish the surfaces to get rid of
the defect. 2
See the replacement procedure
for the cassette sealing, in the
repair chapter. Always install the sealing with a mounting tool spe-
cified by ABB.
Never hammer directly on the sealing as this may
result in leakage. 3
Note
A new sealing has an initial wear that can cause lubricant to seep out and in
some cases produce minor residues of rubber particles.
This is normal behavior of the sealing and does not indicate a seal problem. Wipe
the surrounding surfaces after initial run time.
Flange sealings and static sealings
The following procedure describes how to fit flange sealings and static sealings.
Action
Check the flange surfaces. They must be even and free from pores. 1
It is easy to check flatness using a gauge on the fastened joint (without sealing com-
pound).
If the flange surfaces are defective, the parts may not be used because leakage could
occur.
Clean the surfaces properly in accordance with the recommendations of ABB. 2
Distribute the sealing compound evenly over the surface. 3
Tighten the screws evenly when fastening the flange joint. 4
