Precise filling volumes of still water are filled in plastic bottles with the highest standards of microbiological and hygienic safety. The centrepiece of the machine is a filling pipe whose inlet aperture possesses a diameter of between 40 and 100 mm, depending on the size of the bottling system. The carousel is filled via the column. The column is fitted with one locating and one floating bearing, respectively. The bearings used must be lubricant-free and also non-corrosive.
Franke bearing assembly series LDC 250 as angular contact ball bearing.
The bearing assembly is designed to be suitable for food in a non-corrosive version with bearings made of oxide ceramics. The bearing operates with revolutions of 10 rpm and possesses a radial and axial run of 0.03 mm. The bearing absorbs axial forces of 1500 N emanating from the filling pipe. The components are heated to 130°C every 48 hours in order to kill germs. To satisfy hygienic requirements, the bearing assembly is designed to be lubricant-free, i.e. uses a special lubrication with food industry grease.
