Preventing the Simmerring, particularly the sealing lip,
from contact with sharp edges and any kind of contamination
is essential during handling and installation.
The list of possible problems is intended to be of use to the
user when handling and fitting Simmerring so that the user can
recognize problems and take remedial action in the following
areas

Handling
Numerous possible problems have causes that can easily
be avoided by some simple steps. In practice, however, the
care required during handling is frequently neglected. Some
examples from the comprehensive list of issues are:
A
Pay attention to damaged packaging
A
Leave seals in packaging as long as possible until
installation
A
Do not leave seals lying around loose
A
Protect seals from dust and dirt
A
Safeguard seals in a sealed or covered state
A
Only use clean grease or oil
A
Avoid excessive greasing
A
Do not bring sealing edge into contact with a sharp edge
or with a damaged installation tool
A
Avoid metal chips
A
Sharp-edged chamfers on the shaft and bore are not
permitted
A
Damage and corrosion of shaft and bore are not permitted
A
Pay attention to alignment of bore and shaft.
Positioning of the seal
For most uses only one single seal is necessary. For position-
ing of vertical or inclined shafts, the installation of two seals,
one behind the other in the same installed direction, is recom-
mended for seals that lie below the oil level.
The space between the seals is to be used as a lubrication
chamber. It is recommended to make provision for re-greasing.
The Simmerring can only fulfill sealing tasks and is not suitable
as a guide for machine components or for the transmission of
axial forces.
The Simmerring and accompanying shaft contact surface are
greased before fitting in order to ensure lubrication for the
initial revolutions of the shaft.
