UV resistance
UV
Plain bearings can be exposed to constant weathering
when they are used outside. The UV resistance is an
important measurement and indicates whether a material
is attacked by UV radiation. The effects can extend from
slight changes in colour to brittleness of the material.
Testresults show that iglidur plain bearings are suitable
for outside use. Only for a few iglidur materials are any
changes expected.

drylin linear technology ...
... 100% lubricant-free
Maintenance-free lead screw drives
drylin is a range of maintenance-free and lubricant-free linear bearings in six different options.
In addition the range is complemented by complete linear units with lead screw drive or toothed belt
drylin lead screw drives are always based on self-lubricating plastic nuts
and thus enable a life-long operation without external lubrication.
The lead screws (trapezoidal thread or steep thread) remains in dry operation,
providing many technical advantages. For example, dirt does not stick to
lubricants. The screw drive can thus be used on the one hand in applications
with extreme dirt accumulation and on the other in the hygiene sector. Different
thread types cover a wide range of applications.

dryspin technology is based on specially for lead screw
drives developed wear-resistant igus high performance
polymers.
Matching to plastic nut and lead screws properties
and geometries dryspin offers longer service life and
efficiency for high helix lead screw threads.

Multidimensional ...
... reliably in use
PSE AG, Freiburg, Germany:
This test rig solar systems was able to be built thanks
to the use of igus e-chains. These are the only ones
that allow the test surface to be turned through 380.
Realize 900 and more with igus-rotating
modules also with high loads
RWenergy in Schwandorf, Germany:
Energy supply system from igus GmbH, Cologne,
in the one-axis tracking system.
With the rotation module you can implement larger angles of rotation of 900 and more. Thanks
to add-on modules the angles of rotation can be extended virtually indefinitely. The rotation and
add-on modules are ideally suited for rotary motions with high fill weights and limited space.
CONERGY in Spain:
With the SolarOptimus systems, solar power plant
operators in sunny regions can increase their yields
by more than 30%.

The iglidur bushings are installed in the main
axles of the tracking system: They provide lowfriction rotary movements even under unfavorable
conditions. For the kinematics of the adjustment
system, Conergy decided on the drylin linear
bearings.
