Quality from the
igus® laboratory
Tested thousands of times,
proven millions of times.
Applications involving high duty cycles, speeds and accele-
rations or demanding environmental conditions require pro-
ven systems especially for e-chains®, cables, polymer bea-
rings and linear systems. igus® constantly conducts tests
at its own laboratory under real-world conditions. Every
year, we conduct more than 4,100 tests on e-chains® and
cables, and over 9,600 tests on plain bearings. These tests
focus on push/pull forces, friction values and wear rates.
Other factors like dirt, weathering, cold and impact are
also tested.
Our laboratory is also at your disposal. If we don’t have
data for your type of application, we can conduct a test
representative of your requirements.
The results of more than 15,000 tests are fed to our database
annually.
All products are tested and available from a
single source. Examples of test certificates
and quality seals for igus® products:

igus® – close to
the customer
since 1964
From a garage to the global market with
tribopolymers
What began in 1964 with a single injection moulding
machine in a garage in Cologne has within half a century
become a global enterprise. It all started more than 50 years
ago when Günter Blase, who established the company,
had an idea about the potential of polymer materials. A
mere one year after the company was established, an
injection moulding machine about the same size as a
sewing machine was used to make the very first products;
in 1983, a lubrication-free and maintenance-free iglidur®
bearing was made for the first time in a serial production
process. From then until today, the company has developed
around 50 dierent catalogue materials, which are the basis
of "dry-tech®" bearing technology and are being used in
many, many applications all over the world.
Today, the 2,950 employees come up with new ideas daily,
make high-quality products, ensure streamlined processes
and delivery times and, above all, stay close to the customer.
On average, igus® dispatches around 5,500 consignments
per day. In order to ensure speedy and individual delivery,
the customers receive exactly the product they need for
their application from 14 storage and assembly/installation
centres worldwide: as a single component or as a complete
system, also installed or assembled on site upon request.

Improve technology ... Reduce cost.
For years the igus® motto has been "plastics for longer life®". By this we mean the production of innovative plastic products
which reduce maintenance work, achieve technical improvements, at the same time as reducing costs and increasing
service life, everything delivered immediately from stock. Our references from the practise show the proven employment
from igubal® bearings in a wide variety of applications.
SPREADERS
Main reasons for iglidur® bearings: The special design
to complement the centrifugal arm results in a significant
reduction of manufacturing costs. It is also maintenance-
free and has high wear resistance.
(Fella Werke GmbH & Co. KG)
AXLE BOX ARRANGEMENT
The edge load is usually a deciding factor for or against
the use of bearings. iglidur® G bearings solve this, also
giving high wear resistance, low costs, resistance to
corrosion and dirt.
(Zunhammer GmbH Gülletechnik)
WASHING CHAIN BEARINGS
Reduction of the drive power for bottle washing machines
by using iglidur® under the most dicult conditions in a
2–3 % caustic soda and temperature of +80 °C.
(Krones AG)
TUBULAR BAG MACHINES
The continuous operating temperature in the bonding
arms frequently reach +160 °C and higher. These re quire-
ments are met by iglidur® Z bearings which also oer
particularly high resistance to wear.
(Aeldt Verpackungsmaschinen GmbH)
TOOL CHANGER CHAIN
Main reasons for iglidur® bearings: Enormous cost
ad van tages in comparison to standard metallic rolled
bearings as well as low coecient of friction also with
soft shaft materials.
(Deckel Maho Seebach GmbH)
SURGICAL LIGHT
The motor-powered swivelling LED wings are adjusted
with the aid of iglidur® JVFM bearings. Lubrication and
maintenance-free.
(Trumpf iLED Medical Systems Inc.)
ROLLERCOASTER
Here iglidur® Z bearings led to significant reduction
of the costs. This was achieved by eliminating the
maintenance work completely during the season.
With iglidur® Z bearings it is not necessary to check or
relubricate the units and shafts. Also it was possible
to reduce the weight.

dry-tech®: Enhance technology without
lubrication – Reduce cost by using
tribopolymers
igus® dry-tech® bearings oer an alternative to lubricated
plain, linear and roller bearings. igus® develops tribopolymers
for continuous dry-running operation. By avoiding lubri ca-
tion, dry-tech® bearing technology attains superior service
life: from –100 °C up to +250 °C at continuous exposure,
from cleanrooms to extreme dirt, from vacuum to extreme
humidity. Reduce cost with igus® dry-tech® bearings. A
direct product comparison shows that you can reduce your
current costs for bearing components by as much as 50 %.
dry-tech® bearing technology | Lubrication-free made easy
Change now and save up to 40 %
Tested thousands of times Proven millions
of times.
Applications with high cycle rates, speeds and accelerations
in demanding environmental conditions require tested and
reliable systems for all igus® products. igus® constantly
conducts tests in its in-house laboratory under real-world
conditions. Every year, more than 9,600 tests are conducted
on plain bearings and over 4,100 tests on e-chains® and
cables. The findings go into a unique knowledge database
on the tribology of maintenance-free plastic plain bearings.
Our laboratory is also at your disposal. If we don’t have
data for your type of application, we can conduct a test
representative of your requirements.
Picture 01: igus® lab: 15,000 tribological tests (friction and wear) in 300 test set-ups in the industry's largest labora-
tory (2,750m2). View inside bearing laboratory in Cologne.
iglidur® plain bearings made of high
performance polymers
Extremely wear-resistant tribopolymers improved by
precisely harmonised additions of strengthening materials
and solid lubricants, tested a thousand times and proved a
million times – that is iglidur®. igus® engineers develop and test
more than 100 new plastic compounds every year. The finely
harmonised combination of plastic matrix, strengthening
components and solid lubricants in every single tribopolymer
results in an individual properties profile in each case. In
more than 10,000 individual tests a year on over 200 test
stands in the igus® test laboratory, all existing and potential
iglidur® materials, as well as other materials, are thoroughly
tested. The findings go into a unique knowledge database
on the tribology of maintenance free plastic plain bearings.
This database enables us to select the ideal iglidur® plain
bearing for our customers depending on the application
and to calculate its anticipated service life. If necessary, it
is also possible to develop an application-specific material,
exactly adapted to the thermal, mechanical and tribological
requirements, which goes beyond the existing iglidur®
range. In addition, freely accessible online tools simply to
use enable every user to select his personal sliding bearing
from iglidur® product range. Whether iglidur® product
finder or iglidur® service life calculation, piston ring or bar
stock configurator: with few clicks and applications related
information a suitable bearing is quickly found.

The traditional solution
Hard shells with soft coating. Every lubricated bearing
works according to this principle, and also a number of
maintenance free bearings that are equipped with special
slide layers. However, this soft slide layer is not strong
enough. For high loads, edge pressure or oscillations, it
is easily removed.
Base polymers and technical fibres
The radial pressure with which the bearings are loaded
is received by the polymer material. In the contact area,
this material provides a support to the shaft. The polymer
base material ensures that the lubricants do not receive
a surface pressure that is too high. The base material is
also reinforced by technical fibres or filling materials. These
additional materials stabilise the bearing especially in cases
of continuous load.
Incorporated self-lubrication
The solid lubricants are, as microscopically small particles,
embedded in millions of tiny chambers of the mostly fibre
reinforced material. From these chambers, the plain
bearings release tiny amounts of solid lubricants during
movement. This is adequate to sufficiently lubricate
the immediate surrounding area. The lubricants help
to reduce the iglidur® bearing's coefficient of friction.
They are not indispensable for the bearing's function,
but have a supporting eect. Since they are embedded
in the tiny chambers, they cannot be forced out. They
are always there as soon as the bearing or the shaft is set
in motion.
The iglidur® solution:
the self-lubricating eect
The high-performance polymers of the iglidur® plain
bearings consist of:
Base polymer
Fibres and filling material
Solid lubricants
These components are not applied in layers, but instead
are mixed together homogeneously. The advantage of
this design is clear when the requirements on the bearings
surface are studied:
1. The coecient of friction, which is determined
especially by the surface of the bearing, should
be as low as possible.
2. The surface cannot be removed by forces that
act on the bearing.
3. The wearing force acts especially on the surface
of the bearing, for this the bearing must be
capable of high resistance.
One universal material, which can fulfil all these tasks
equally well, unfortunately does not exist yet. That is
why iglidur® plain bearings work dierently. Dierent
components of the iglidur® materials give the bearings
their properties:
The base polymers are responsible for the
resistance to wear.
Fibres and filling materials reinforce the
bearing so that high forces or edge loads are
possible.
Solid lubricants lubricate the bearing
independently and prevent friction of the system.

Properties and design
The load of a plain bearing is expressed by the surface
pressure (p) in MPa (corresponding to N/mm2). For this
purpose, the radial load is determined on the projected
surface of the bearing.

In these equations:

b1 bearing length in [mm]
d2 outer diameter of the bearing in [mm]
Max. permissible surface pressure
A comparative value of the iglidur® material is the
recommended maximum static surface pressure [MPa] at
+20 °C. The values of the individual iglidur® plain bearings
differ greatly on this point. The value [p] indicates the
pressure limit of a plain bearing. The plain bearing can carry
this pressure permanently without damage. The given value
applies to static operation; only very slow speeds up to 0.01
m/s are tolerated under this pressure. Higher pressures
than those indicated are possible if the duration of the load
is short.
Material table, page 56
Load and temperature
Diagram 02 and 03 show the recommended maximum
static surface pressure [p] of the iglidur® plain bearing as a
function of temperature. With increasing temperature,
this value decreases continuously. Take advantage of the
opportunity presented by the predictability of the iglidur®
plain bearing to record these eects in advance, or deter-
mine the eective temperatures in the test.
Pressure and speed
With decreasing radial load on the plain bearing, the
permissible surface speed increases. The product of
the pressure [p] and speed [v] can be understood as a
measurement for the frictional heat of the bearing. This
relationship is shown by the pv diagram that is the first in
the respective chapter for each iglidur® material.

The load of the plain bearing has an eect on the wear of the
bearing. The following diagrams show the wear behaviour of
the iglidur® bearing materials. It is easily recognised that for
each pressure, there is an optimal plain bearing available.
The wear is shown as a wear rate in [μm/km].

Pressure and wear
Diagrams 05–07: Wear of iglidur® plain bearings under low pressures
With increasing load, the coecient of friction of the plain
bearing typically decreases. In this context, shaft materials
and the surface finish are also significant.

The peripheral speed is always significant in plain bearings.
Crucial is not the absolute rotation speed, but the relative
speed between the shaft and the bearing. The surface
speed is expressed in meters per second [m/s] and calcula-
ted from the rotary speed n [rpm] with the following formula.
With varying speed like seen for example with oscillating
movements, the value needed is the average speed (see
above formula).
Permissible surface speeds
iglidur® plain bearings were primarily developed for low
to average surface speeds in continuous operation. Table
01 shows the permissible surface speed of iglidur® plain
bearings for rotating, oscillating, and linear movements.
These surface speeds are limit values assuming minimum
pressure loading of the bearing. In practice, these limit
values are rarely reached due to an inverse relationship
between load and speed. All increases of the pressure
leads unavoidably to a reduction of the allowable surface
speeds and vice versa.
The speed limit is determined by the thermal properties of
the bearing. This is also the reason why dierent surface
speeds can occur for the dierent movement types. For
linear movements, more heat can be dissipated via the
shaft, since the bearing uses a longer surface area on the
shaft.
Surface speed and wear
Considerations regarding the permissible surface speeds
should also include the wear resistance of the plain bearing.
High surface speeds automatically bring correspondingly
high wear rates with them. With higher sliding speed, not
only the wear rate rises but also the absolute wear.
Surface speed and coecient of friction
In practice the coecient of friction of plain bearings is
a result of the surface speed. High surface speeds have
a higher coecient of friction than low surface speeds.
Diagram 08 shows this relationship by using the example
of a cold rolled steel shaft (Cf53) with a load of 0.7 MPa.
