EN 2. Lubricants
2. Lubricants
2.1 General information
Lubricants are used specifically for cer-
tain application purposes. In order to fulfil
their tasks, lubricants must fulfil various
requirements.
The most important requirements for lubri-
cants are:
○Reduction of abrasion and wear
○Corrosion protection
○Noise minimisation
○protection against contamination or
penetration of foreign objects
○Cooling (primarily with oils)
○longevity (physical/ chemical stability)
○economic and ecological aspects
2.2 Selection of lubricants
SKF considers lubricants to be an element
of system design. A suitable lubricant is se-
lected already when designing the machine
and forms the basis for the planning of a
centralized lubrication system.
The selection is made by the manufacturer
or operator of the machine, preferably to-
gether with the lubricant supplier based on
the requirement profile defined.
Should you have little or no experience with
the selection of lubricants for centralized lu-
brication systems, please contact SKF.
If required we will be glad to support cus-
tomers to select suitable components for
feeding the selected lubricant and to plan
and design their centralized lubrication
system.
You will avoid possible downtimes through
damage to your machine or system or
damage to the centralized lubrication
system.
2.3 Material compatibility
Lubricants must generally be compatible
with the following materials:
○steel, grey iron, brass, copper, aluminium
○NBR, FPM, ABS, PA, PUR, PETP
2.4 Temperature characteristics
The lubricant used must be suitable for the
specific ambient temperature of the product.
The viscosity required for proper operation
of the product must be adhered to and must
not be exceeded in case of low temperatures
nor fall below specification in case of high
temperatures. Specified viscosities, see
chapter Technical data.

951-171-236
Version 01
EN
2. Lubricants
w
Only lubricants specified for the
product (see chapter Technical
data) may be used. Unsuitable
lubricants may lead to a failure of
the product.
Do not mix lubricants. This may
have unforeseeable effects on
the usability and therefore on the
function of the centralized lubri-
cation system.
When handling lubricants the rel-
evant safety data sheets and haz-
ard designations, if any, on the
packaging have to be observed.
2.5 Ageing of lubricants
After a prolonged downtime of the machine,
the lubricant must be inspected prior to
re-commissioning as to whether it is still
suitable for use due to chemical or physical
ageing. We recommend that you undertake
this inspection already after a machine
downtime of 1 week.
If doubts arise as to a further suitability of
the lubricant, please replace it prior to re-
commissioning and, if necessary, undertake
initial lubrication by hand.
It is possible for lubricants to be tested in the
company's laboratory for their suitability for
being pumped in centralized lubrication sys-
tems (e.g. "bleeding").
Please contact SKF. if you have further ques-
tions regarding lubricants.
You may request an overview of the lubri-
cants tested by SKF.
Due to the multitude of possible
additives, individual lubricants,
which according to the manu-
facturer's data sheets fulfil the
necessary specification, may not,
in fact, be suitable for use in cen-
tralized lubrication systems (e. g.
incompatibility between synthetic
lubricants and materials). In
order to avoid this, always use
lubricants tested by SKF.

3. Overview, functional description
The injection oilers described in these in-
structions are pneumatic piston pumps that
dispense lubricating oil in an unchangeable
quantity.
Corresponding to the variant of the injection
oiler, the lubricating oil is supplied either from
the installed reservoir or from a lubricant feed
line to be connected by the operator.
After each activation the injection oilers must
be relieved from pressure to allow the piston to
return into its initial position. The compressed
air is controlled by a way valve to be provided
by the operator.
