2.1 General information
Intended use is the use of the products for
the purpose of providing centralized lubri-
cation/lubrication of bearings and friction
points using lubricants within the physical
usage limits which can be found in the doc-
umentation for the devices, e.g., operating
instructions and the product descriptions,
e.g., technical drawings and catalogs.
Particular attention is called to the fact that
hazardous materials of any kind, especially
those materials classified as hazardous by
EC Directive 67/548/EEC, Article 2, Para.
2, may only be filled into SKF centralized
lubrication systems and components and
delivered and/or distributed with such
systems and components after consulting
Selection of a lubricant suitable for the
lubrication task is made by the machine/
system manufacturer and/or the operator of
the machine/system in cooperation with the
lubricant supplier.
When selecting a lubricant, the type of
bearings/friction points, the expected load
during operation, and the anticipated ambi-
ent conditions must be taken into account.
All economic and environmental aspects
must also be considered.
NOTE
Observe the instructions from the machine
manufacturer regarding the lubricants that
are to be used. The amount of lubricant
required at a lubrication point is specified
by the bearing or machine
manufacturer. It must be ensured that the
required quantity of lubricant is provided
to the lubrication point. The lubrication
point may otherwise not receive adequate
lubrication, which can lead to damage and
failure of the bearing.
2.2 Selection of lubricants
NOTE
All products from SKF Lubrication
Systems may be used only for their in-
tended purpose and in accordance with
the information in the product's operating
instructions.
with and obtaining written approval from
SKF Lubrication Systems.
No products manufactured by SKF Lubrication
Systems are approved for use in
conjunction with gases, liquefied gases,
pressurized gases in solution, vapors, or
such fluids whose vapor pressure exceeds
normal atmospheric pressure (1013 mbar)
by more than 0.5 bar at their maximum
permissible temperature.
Other media which are neither lubricant nor
hazardous substance may only be fed after
consultation with and written approval from
SKF Lubrication Systems.
SKF Lubrication Systems considers lubricants
to be an element of system design that
must always be factored into the selection
of components and the design of centralized
lubrication systems. The lubricating properties
of the lubricants are critically important in
making these selections.

18
EN 2. Lubricants
Please contact SKF Lubrication Systems
if you have further questions regarding
lubricants. It is possible for lubricants to be
tested in the company's laboratory for their
suitability for pumping in centralized lubri-
cation systems (e.g., "bleeding").
You can request an overview of the lubricant
tests offered by SKF Lubrication Systems
from the company's Service department.
The product described here can be operated
using lubricants that meet the specifications
in the technical data. Depending on the
product design, these lubricants may be oils,
fluid greases, or greases.
Mineral, synthetic, and/or and rapidly bio-
degradable oils and base oils can be used.
Consistency agents and additives may be
added depending on the operating condi-
tions.
Note that in rare cases, there may be
lubricants whose properties are within the
permissible limits values but whose other
characteristics render them unsuitable for
use in centralized lubrication systems. For
example, synthetic lubricants may be in-
compatible with elastomers.
NOTE
Only lubricants approved for the product
may be used. Unsuitable lubricants can
lead to failure of the product and to property
damage.
2.3 Approved lubricants
NOTE
Different lubricants must not be mixed
together. Doing so can cause damage and
require costly and complicated cleaning of
the product/lubrication system. It is
recommended that an indication of the
lubricant in use be attached to the lubri-
cant reservoir in order to prevent acciden-
tal mixing of lubricants.
NOTE
If necessary, SKF Lubrication Systems can
help customers to select suitable compo-
nents for feeding the selected lubricant
and to plan and design their centralized
lubrication system.

2.5 Lubricant hazards2.4 Lubricants and the environment
NOTE
Lubricants can contaminate soil and
waterways. Lubricants must be properly
used and disposed of. Observe the local
regulations and laws regarding the disposal
of lubricants.
It is important to note that lubricants are
environmentally hazardous, flammable
substances which require special precau-
tionary measures during transport, storage,
and processing. Consult the safety data
sheet from the lubricant manufacturer
for information regarding transport, storage,
processing, and environmental hazards of
the lubricant that will be used.
The safety data sheet for a lubricant can be
requested from the lubricant manufacturer.

Lubricants
Gerotor pumps must always be
free of leaks. Leaking lubricant is
hazardous due to the risk of slip-
ping and injury. Beware of any
lubricant leaking out during as-
sembly, operation, maintenance,
or repair of centralized lubrication
systems. Leaks must be sealed off
without delay.
Lubricant leaking from centralized lubrica-
tion systems is a serious hazard. Leaking
lubricant can create risks that may result
in physical harm to persons or damage to
other material assets.
NOTE
Follow the safety instructions on the lubri-
cant's safety data sheet.
