2.1 General
CAUTION
All products must be used only as intended
and in accordance with the requirements in
the manual.
Intended use is the use of the products for
the purpose of lubricating bearings and
friction points with lubricants in accordance
with the physical operating limits, which
can be found in the respective product
documents, such as the operating manual
and product descriptions, e.g. technical
drawings and catalogues.
It is pointed out that hazardous materials
of any kind, especially materials classified as
hazardous according to Directive 67/548 /
EEC, Article 2, paragraph 2, may only
be filled and then used for conveying /
distribution following consultation with
and written approval from SKF centralised
lubrication systems and components.
All products manufactured by SKF are not
approved for use in conjunction with gases,
liquefied gases, gases dissolved under
pressure, vapours and those liquids whose
vapour pressure at the maximum allowable
temperature is greater than 0,5 bar above
normal atmospheric pressure (1013 mbar).
If other media that are neither lubricants
nor hazardous substances be encouraged,
this is only permitted by SKF following
consultation and written approval.
SKF considers lubricants to be a structural
element that must be included in the
selection of components and in the
design of centralised lubrication systems.
The lubricant properties must be strictly
adhered to.
2.2 Lubricant selection
CAUTION
Observe the instructions of the
machine manufacturer on the lubricants
to be used.
The lubricant needs of a lubrication point
is specified by the bearing or machine
manufacturer. Ensure that the required
amount of lubricant is provided to the
lubrication point. Otherwise, insufficient
lubrication and thus damage and failure of
the bearing point could follow.
A suitable lubricant for the lubrication
task is chosen by the machine / system
manufacturer or the operator of the
machine / system along with the lubricant
supplier.
The selection is made taking into account
the nature of the bearing / friction points
to be lubricated, their expected strain
during operation and the expected ambient
conditions, taking into account economic
and ecological aspects.

16
EN 2. Lubricant
CAUTION
As needed, SKF supports customers
in choosing suitable components for
conveying the selected lubricant and in the
planning and design of a central lubrication
system.
Please contact SKF if there are any further
questions about lubricants. It is possible
to test lubricants in our own laboratory
for eligibility (e.g. "bleeding") for use in
centralised lubrication systems.
An overview of the lubricant tests offered
by SKF can be obtained from the sales
department of SKF.
2.3 Permitted lubricants
CAUTION
Only the lubricants that are permitted
for the product may be used. Unsuitable
lubricants could lead to failure of the
product and to property damage.
CAUTION
Various lubricants must not be mixed,
otherwise, damage may occur and
expensive cleaning of the product may
be necessary. To avoid confusion, it is
recommended to attach a note about the
used lubricant on the lubricant container.
The product described may be used
with lubricants in accordance with the
specifications in the technical data.
Depending on the version of the product,
this could be oils, fluid greases or greases.
The oils and base oils may be rapidly
degradable mineral, synthetic and / or
biological. The addition of consistency
builders and additives depends on the
operating conditions.
It is to be remembered that, in some cases,
there may be lubricants that are not suitable
for use in centralised lubrication systems
because of other properties, even though
their characteristics lie within the permitted
limits. With synthetic lubricants, for
example, this can lead to incompatibilities
with elastomers.

2.4 Lubricants and the environment
CAUTION
Lubricants can contaminate soil and
waterways. Lubricants must be used
and disposed of professionally. The
relevant regulations and laws governing
the disposal of lubricants are to be
observed.
In principle, it should be noted that
lubricants are environmentally hazardous
and flammable materials, whose transport,
storage and processing require special
precautions. Information on transportation,
storage, processing and environmental
hazards can be found in the safety data
sheet of the lubricant manufacturer of the
lubricant to be used.
The safety data sheet can be requested from
the lubricant manufacturer.
2.5 Dangers from lubricants
WARNING
Danger of slipping and injury
Leaked lubricant poses a source of
hazard.
Promptly repair leaks and remove
