SURFING ON
TARMAC
WITH WEAR-RESISTANT IGUS
PLAIN BEARINGS
The Curfboard is a new type of sports equipment that
combines a surfboard and a skateboard and in the
process, has to withstand extreme loads. Especially high
are the demands on its moving components, including
the bearings. Developers at the curfboard GmbH rely
on wear-resistant plain bearings made of iglidur Z and
iglidur J350 high-performance polymers from igus.

Maintenance engineers around the world are changing to Gates Poly Chain
GT belts. In comparison with other belts, Poly Chain GET drives weigh up
to 35% less, use sprockets that are up to 67% narrower and have up to
4 times more power. Gates Poly Chain GT belts last longer, require no
lubrication and are practically maintenance-free for reduced overall costs.

Whether skating
or surfing, the
curfboard from
curfboard GmbH
combines the two sports in a new
sports and leisure equipment.
So, the manufacturer promises
"the ultimate surf-ride feeling on
wheels". Ensured by the new, special
axes. They do without any rubber
dampers or springs and have a
4-joint kinematics, which makes
them self-regulating. Gravity assists
the automatic adjustment to the
weight of the rider. In addition,
the board has a better response
behaviour, making it easier to
control.
Another special feature is that the
rider no longer has to push off to
move. Instead, similar to surfing,
speed is built up by shifting the
body's weight – and even uphill. The
demands on the components are
therefore particularly high. While
the skateboard stresses the axles
and the bearings particularly when
cornering, the curfboard is exposed
to stress all the time. To withstand
these stresses, Stephan Augustin,
the inventor of the Curfboard,
chose wear-resistant plain bearings
made of iglidur Z and iglidur J350
high-performance polymers.
In search of the appropriate plain
bearings, Stephan Augustin
initially carried out a four-month
outdoor test under the harshest
conditions with bearings from
various manufacturers. "After
evaluating the test results, it
became apparent that only the
igus plain bearings made of
iglidur Z and iglidur J350 met the
requirements," explains Stephan
Augustin. Whereas metal/
PTFE composite plain bearings
wore out after a short time and
completely failed, the iglidur plain
bearings of the motion plastics
specialist were able to prove
themselves. Since the plain
bearings had to be abrasionresistant
and at the same time
corrosion-free and maintenancefree
despite the permanent high
loads, the manufacturer chose
the high-performance plastic
iglidur Z for the bearings directly
on the boom.
