Lubrication-free iglidur J plain bearings for wine production

Lubrication-free and maintenance-free polymer bearings are replacing
metallic alternatives in wine production processes, helping improve service
life and hygiene. iglidur J plain bearings from igus are now being used in grape
destemming machines, which carefully separate the grapes from the stems in a
rotating drum-like sieve.

Australia is the fifth largest wine producer in the world, producing
approximately 13.7 million hectolitres of wine every year. After harvesting,
gentle processing of the grape plays a critical role in the quality of the
wine. Traditionally, grapes were harvested from the vines by hand and then
crushed by feet in a large vat. To avoid bitter tannins in the wine, the stems
and stalks were already removed during harvesting.

Though the principle of wine production has not changed much over the
centuries, machines have replaced several of the manual processes right from
harvesting when the grapes are machine picked with the stems and stalks still
attached, to separating the bitter stems and stalks in destemming machines. The
environment of dirt, wood and must is a real challenge for the bearings.

Therefore, iglidur J bearings are used in the destemming machines from
Siprem International. In California alone, 130,000 litres are channelled
through the facilities of Siprem International in just two months.

iglidur J bearings are lubrication-free and chemical-resistant, and have
a low moisture absorption rate, enabling a reliable, continuous rotation of the
drum. The metallic bearings used previously had to be continuously serviced and
replaced due to the wood residue. They were ultimately replaced by polymer
plain bearings from igus.

iglidur bearings, available from Treotham Automation, have been designed
to increase the service life of the machine and reduce its downtime.
