Rotating seals
The procedure below describes how to fit rotating seals.
CAUTION
Please observe the following before commencing any assembly of seals:
•
Protect the sealing surfaces during transport and mounting.
•
Keep the seal in its original wrappings or protect it well before actual
mounting.
•
The fitting of seals and gears must be carried out on clean workbenches.
•
Use a protective sleeve for the sealing lip during mounting, when sliding
over threads, keyways, etc.
Note
Action
Check the seal to ensure that:
•
The seal is of the correct type (provided with cutting
edge).
•
There is no damage to the sealing edge (feel with a
fingernail).
1
Inspect the sealing surface before mounting. If scratches
or damage are found, the seal must be replaced since it
may result in future leakage.
2
Article number is specified
in
Lubricate the seal with grease just before fitting. (Not too
early - there is a risk of dirt and foreign particles adhering
to the seal.)
3
Fill 2/3 of the space between the dust tongue and sealing
lip with grease. The rubber coated external diameter must
also be greased, unless otherwise specified.
Mount the seal correctly with a mounting tool.
4
Never hammer directly on the seal as this may result in
leakage.
Make sure no grease left on the robot surface.
