Sterile or aseptic filling is unavoidable when bottling beverages. The PET bottle is at the heart of the global beverage industry known as "the ideal packaging". Wherever there may be direct contact between the beverage and the filling technology, special attention must therefore be paid. The roller bearings used in the filling/capping head must therefore comply with hygiene requirements. Here it is particularly important: The bearings must be CIP compatible! Conventional steel bearings cannot do this: The bearings would have to be lubricated, whereby lubricants could contaminate the product. Even worse: The sealing washers installed in the bearing would be "washed out" and cavities would be created in the bearing which would allow dangerous germination.
This is where our hybrid bearings (rings made of special steel, balls made of silicon nitride) come into play: Our bearings are open and are therefore hygienically set to "zero" for every CIP process. The combination of our special steel/ceramic combination makes operation WITHOUT grease possible. In addition to these hygienic conditions, our bearings are extremely corrosion resistant to H2O2 and PAA
