CAUTION
Please observe the following before commencing any assembly of sealings:
• Protect the sealing during transport and mounting, especially the main lip.
• Keep the sealing in its original wrappings or protect it well before actual
mounting.
• The fitting of sealings and gears must be carried out on clean workbenches.
• Use a protective sleeve for the main lip during mounting, when sliding over
threads, keyways or other sharp edges.
Action
Check the sealing to ensure that:
• The sealing is of the correct type.
• There is no damage on the main lip.
Inspect the shaft surface before mounting. If scratches
or damage are found, the shaft must be replaced since
it may result in future leakage. Do not try to grind or
polish the shaft surface to get rid of the defect.
Lubricate the sealing with grease just before fitting.
(Not too early - there is a risk of dirt and foreign
particles adhering to the sealing.)
Fill 2/3 of the space between the dust lip and the main
lip with grease. If the sealing is without dust lip, just
lubricate the main lip with a thin layer of grease.
