Lubrication-free bearings reduce costs in frying oil filtration equipment

• What was needed: iglidur plain bearings
• Requirements: all components need to withstand very high temperatures and aggressive cleaning agents.
• Industry: food technology
• Success for the customer: bearings made of the high-performance material iglidur A500 work reliably even when subjected to hot steam and so-called peracetic acids for cleaning.

Food safety is at the top of the list of priorities in Europe. In the case of frying oil, devices such as the VITO filtration device from SYS Systemfiltration GmbH are used here. As the name suggests, the particularly compact and mobile VITO device is a system for cleaning frying oil simply and efficiently, thus at least doubling the downtime.
The highest standards apply to all components used, not only with regard to the high temperatures prevailing there, but also with regard to aggressive cleaning agents. A suitable material that could fulfil the requirements also had to be found for the bearing of the filtration unit's rotor.

For the bearings of the rotor, the choice finally fell on plain bearings made of the high-performance material iglidur A500. The bearings are located in the pump module and are directly exposed to the hot oil. Almost every part is cleaned with hot steam and also peracetic acids. Machine manufacturers and users from the food, filling and packaging industries therefore require resistance to such substances. In order to do justice to this claim, the values and officially confirmed plain bearing specifications stated in our product catalogue are always preceded by scientific tests with regard to durability.If there is direct contact between the plain bearing and the product to be processed or packaged, as in the case of the VITO for the bearing of the agitator, the requirement for an FDA-approved material certainly determines the selection of the bearing.
