. Lubricants
. General
NOTE
All SKF products must only be used for their intended purpose
and in accordance with the specifications of the installation ins-
tructions for the product in question.
The intended use of this product is for the centralized lubrication/
lubrication of bearings and wear points with lubricants. All physical
limitations of use stipulated in the documentation of the product
such as the owner’s manual, technical drawings and catalogs must
be observed.
More specifically, we call your attention to the fact that substances
and mixtures classified as hazardous by the Annex I part - of the
CLP regulation (EC /), and identified with hazard picto-
grams GHS-GHS and GHS, can only be used to feed the SKF
centralized lubrication systems, transported or distributed by these
systems after consultation with SKF and obtaining written
permission.
All products manufactured by SKF are not approved for use in
conjunction with gases, liquefied gases, pressurized gases in solution
and fluids with a vapor pressure exceeding normal atmospheric
pressure ( mbar) by more than , bar at their maximum per-
missible temperature.
Should there be a need to use the product to convey media other
than lubricants or hazardous substances, this must be discussed
with SKF first and the company must give express written
permission.
In the opinion of SKF, lubricants constitute a design element that
must be considered when selecting components and designing cen-
tralized lubrication systems. The lubrication properties of the lubri-
cants in question must be considered.
. Selection of lubricants
NOTE
You must observe the machinery manufacturer's information on
the lubricants to be used in the machinery.
NOTE
The manufacturer of the bearing or machinery to be lubricated
will specify the lubricant requirements for each point to be lubri-
cated. You must make sure that the required quantity of lubri-
cant is provided to the relevant lubricating point. If a lubricating
point is insufficiently lubricated, the bearing may become
damaged or jammed.
While the machinery/bearing manufacturer usually specifies lubri-
cants, it is the owner/operator (or maintenance person) who must
finally select the appropriate lubricant, with the help of the lubricant
supplier. When selecting a lubricant, the type of bearing/wear point,
the stresses and strains to be expected during operation, and antici-
pated ambient conditions must be taken into account. All financial/
economic aspects must also be considered.
If you have further questions, you can contact SKF.
We can test lubricants in our own laboratory to establish their
suitability for conveyance (e.g. 'oil separation' behavior) in centralized
lubrication systems.
You can request an overview of lubricant tests offered by SKF from
our Service Center.
. Approved lubricants
CAUTION!
Only lubricants that have been approved by SKF for use with the
product may be used. Unsuitable lubricants can cause product
malfunctions and damage to property.
NOTE
If required, SKF can help customers to select suitable compo-
nents for the conveyance of the selected lubricant and to plan
and design their centralized lubrication system.


CAUTION!
Different lubricants must not be mixed together. Doing so can
cause damage and require extensive cleaning of the products/
centralized lubrication system.To prevent confusion, we recom-
mend that you attach information indicating the lubricant to be
used on the lubricant reservoir.
The described product can be operated with lubricants that comply
with the specifications in the technical data.
Note that some lubricants may have properties that lie within the
permitted limit values and yet not be suitable for use in centralized
lubrication systems for other reasons. For example, some synthetic
lubricants are not compatible with elastomers.
. Lubricants and the
environment
WARNING!
Lubricants can pollute the soil and water. Lubricants must be
used and disposed of in compliance with the rules. Instructions
and local regulations must be observed when handling
lubricants.
Note that lubricants are harmful to the environment and flammable;
their transportation, storage, and processing are subject to special
precautionary measures. For specifications on transportation, sto-
rage, processing, and dangers to the use and the environment for
the lubricant, refer to the material safety data sheet provided by or
available from the lubricant manufacturer. You can ask the manufac-
turer of the lubricant for the material safety data sheet.
. Danger relating to lubricants
CAUTION!
Centralized lubrication systems must be absolutely leak-free.
Leaking centralized lubrication systems can cause a slip hazard.
When performing installation, maintenance, and repairs test the
centralized lubrication system for leaks. Leaky parts of the cen-
tralized lubrication system or components of the lubrication
equipment have to be sealed immediately.
Leaking centralized lubrication systems or components of the lubri-
cation equipment are a source of danger in relation to slip hazard
and the risk of injury. These dangers can cause physical injury to per-
sons or damage to other material assets.
Refer to safety precautions in the lubricant manufacturer's mate-
rial safety data sheet.
Lubricants are hazardous substance. It is essential to respect any
safety instructions given in the lubricant safety data sheet. You can
ask the manufacturer of the lubricant for the material safety data
sheet.

. Function
The function principle of the grease injection system for the lubrica-
tion of conveyor chains is more or less the same for all systems
(† fig. ).
However some models differ from others by the type of lubrication
points, the number of injection heads, etc.
GVP-S-- system
The lubrication system is dedicated to the lubrication of the rollers of
a conveyor chain. It features one injection head and one pick-up
system.
The lubrication system is controlled by a control unit.

A. The GVP unit is in its starting position.
The pick-up system and the injection system
are in their resting position on the carriage.
The proximity switch detects the roller to be
lubricated.
B. Detection of the roller. A signal is sent to
the control unit which triggers an injection
cycle. The pickup system moves forward to
the roller to be lubricated.
C. The pickup finger is in contact with the
roller to be lubricated.
The carriage is now moving exactly in parallel
to the roller. The injection order is sent. The
injection head moves simultaneously forward
onto the roller to be lubricated.
D. Lubrication phase. This phase is the
contact time between the injection head and
the lubrication point (user-configured). The
carriage keeps moving in parallel to the lubri-
cation point.
E. The injection time has elapsed. The injec-
tion head is pulled away from the lubrication
point. The pick-up system is retracted. There
is no more contact between the GVP unit and
the chain.
F. Return to the initial position. The injection
and pick-up systems go back to their waiting
position, as well as the carriage.

. Modification of the injector
metered volume
The GVP lubrication system is delivered with a fixed metered volume.
It is possible to modify later this metered volume. Four different
metered volumes are available: , ; , ; , or  cm/stroke.
The metered volume is adjusted by means of reversible metering
stops.They modify the stroke of the metering piston of the injector,
thus the metered volume. Each injector has two reversible metering
stops († fig. ), one is mounted in the injector, the other delivered
separately.
NOTE
A number of washers screwed on the injector indicate the mete-
red volume of the GVP system († fig. ). Therefore change the
number of washers when modifying the metered volume.
