The wheel and roller specialists from the
Blickle‘s Danish sales agency analysed the
requirements of the Scandinavian company
in detail on site and developed an ideal solution
for this special application based on
Blickle‘s LIX-POTH castor wheel series. The
special feature: The groove ball bearings of
the wheel and the swivel head of the swivel
housing box are lubricated with a special
cold grease for roller bearings, which is suitable
for temperatures down to -70 °Celsius.
This means the moving parts are optimally
protected and work reliably even in extreme
cold. During production, great care is taken
to ensure that no air bubbles are created
when introducing the lubricating grease.
Otherwise, the transition between the extreme
cold and temperatures above zero could
result in the formation of condensation there.
Upon re-entry into the freezer area, this
condensation would freeze, impairing the
function of the wheels and causing increased
The wheels of the POTH series with their
heavy polyamide body and a tyre made of
thermoplastic polyurethane offers a good
performance even in extremely cold conditions:
they also have low roll and swivel
resistance, are quiet-running, easy on floors
and do not leave streaks. They are therefore
predestined for use in sensitive environments.
This solution has already proven itself in
practice. The customer extensively tested
the new wheels – with successful results.
The LIX-POTH castors were much more resilient,
functioned better and broke down
less often under the adverse conditions than
the previously used competitor product. The
company therefore decided to permanently
adopt the wheels.
